Dishwasher does not start washing. Causes of breakdowns and repair of dishwashers Dishwasher problems

A dishwasher is a very important part of the life of every large family. Mountains of dirty dishes - a situation familiar to every housewife, which often spoils the mood, especially after gala dinner. In such situation Dishwasher is a real salvation that saves strength, time, nerves, and saves good mood and cleanliness in the house. However, like any appliance, dishwashers can break down. In this case, it is necessary to carry out urgent repairs of breakdowns of dishwashers in order to maintain harmony in the house.

Causes of breakdowns

If your device is more than five years old, then, most likely, some part simply failed. Diagnosing and replacing the damaged part will help you quickly fix the problem. If you have recently updated your appliances, then the reasons for the breakdown of the dishwasher may be hidden in the following:

1. Cheap assembly or poor quality parts. As a rule, this occurs in models with a suspiciously low cost. If you are the owner of a Bosch, Indesin, Electrolux or Ariston car, then most likely this is not the cause of the breakdown.
2. Presence of food debris. Only dishes with very small particles of food are allowed to be loaded into the machine. If this is not observed, the filters will become clogged, which will cause a possible breakdown.
3. There is no food. A common cause of non-working equipment is a failed outlet.
4. Poor quality detergents. As a rule, brands such as Bosch, Indesit and Ariston recommend certain detergents that do not harm the car. If you purchase more than cheap option, then you will have to spend money on repairing equipment.
5. Misuse. This may include general issues- loose door closing, improper positioning of dishes, loading items that are prohibited for washing in a dishwasher, etc.

These are all reasons, but what do the main breakdowns of dishwashers look like?

Dishwasher won't start

The machine runs, even completes the cycle, and the dishes remain dirty. There are several possible reasons:

1. Filters are clogged with food residue;
2. The nozzles are clogged and, as a result, the water has stopped circulating;
3. The circulation pump went out of standing.

Owners of Bosch, Indesit and Electrolux dishwashers often have the first two problems. This is due, as mentioned above, to improper operation. Diagnosing and fixing such problems is quite simple - just pull out and rinse the filters, and clean the nozzles with a needle or toothpick. If the problem is not solved, then it is best to contact the service center.

Water overflow occurs

The water level sensor is responsible for the amount of water in the machine. If overflow occurs, then most likely the sensor has become unusable.

In this case, the repair is inexpensive and quite simple - you can replace the sensor with your own hands by turning the dishwasher over (the sensor is located below).

Wrong temperature setting

Many dishwasher manufacturers, such as Bosch and Indesit, install a choice of temperature regime- from 30 to 90 degrees. If you set a certain temperature, and get a clearly inappropriate result, then there may be problems with the temperature sensor:

1. The sensor is out of standing;
2. Water is supplied to the system under insufficient pressure (during repair work on the water supply line);
3. The heater has failed.

It is best to entrust the repair of such a breakdown experienced master at the service center.

No water drain

One of frequent breakdowns dishwashers is the lack of water drain.

Water is drained as follows: water passes through the pump into the hose and the internal filter. Improper use may result in contamination of any of these parts. For some reason, this is the most common Bosch dishwasher failure. Perhaps this is due to the fact that in the dishwasher market, Bosch is the undisputed leader. It was this manufacturer that won the trust of customers, so dishwashers of this particular brand are in most homes.

Fixing a dirty pump problem will be more difficult than a nozzle problem, but the essence is the same - you need to remove the pump, hose and internal filter and rinse them thoroughly.

Another reason for poor water drainage is that the drain hose is too high.

Dishwasher electric shock

This problem is less common than others, but it is one of the main ones. The reason for this behavior of your dishwasher is as follows - the electric heating element has not failed, but it has a breakdown.

Such a problem may arise due to factory defects, due to long-term operation, and also due to increased water hardness.

Diagnostics and repair in this case are carried out at the service center. This is especially important if your device has not yet been removed from warranty service.

Other common faults

One of frequent malfunctions Bosch dishwashers is not taking detergent. There are two options: the nozzles are dirty or the valve for opening the detergent tank is broken. In the first case, the problem is eliminated by simple cleaning, and in the second - by replacing the corresponding valve.

If when you open the dishwasher you see complete absence power supply, then in most cases the main problem is outside the device - the socket is broken or network filter. You can check their performance with any other device. Other causes of the problem may be a damaged power button or a malfunction in the door latch mechanism.

One way or another, a dishwasher is a device that, like many others, can break down. The main causes of breakdowns are, as a rule, incorrect operation or a rather long service life. If you cannot diagnose and fix the problem yourself, then it is best to entrust this matter to professionals, otherwise you can damage the device even more.

So, one day you found that the dishwasher does not turn on, does not drain water or leaks. Do not rush to immediately call the master, because sometimes the cause of a breakdown can be easily eliminated with your own hands without special skills and tools. Next, we will look at possible malfunctions of dishwashers and instructions for their self-repair at home.

What can cause failure?

If the equipment has served you for more than 5 years, and its warranty period has long expired, then possible cause malfunctions can be banal wear of spare parts.

In the event that you have recently made a purchase and the dishwasher has already failed, then the reasons for the breakdown may be as follows:

• Poor build quality and parts. It is found in cheap Chinese models from poorly known manufacturers.
• Before loading dishes into the chamber, you do not wash off food residues that clog the filter. Very dirty dishes most of the dishwasher does not rinse completely, as a result of which it is necessary to additionally rinse manually.
• Socket failure. A banal situation but still sometimes arises.
• Incorrect (for example, the length of the drain hose is longer than allowable value or hose with cold water badly attached).
• Poor detergent that does not clean dishes very well or does not wash dishes at all.
• Perhaps you just did not close the door tightly (the mechanism is designed so that the equipment will not turn on until the latches work). It should also be noted here that for some models the door is not fixed in the lower position. If the door does not hold, this is not a dishwasher failure, but a manufacturer's defect.
• Another fairly popular cause of a malfunction is improper loading of dishes, as a result of which the equipment does not wash the lower section or the upper shelf well. Even the instructions discuss the correct loading - the top must be filled with plates and mugs, the bottom - with overall kitchen utensils (for example, pots). One more important requirement- Glasses and cups should be stacked upside down.

If none of these reasons is the culprit of the failure, then the matter is in the spare parts, which we will discuss later.

Troubleshooting basic types of problems

The dishwashing process does not start

Such a situation: you have turned on a certain mode, all the indicators light up, the sound of water filling is heard from the chamber, it has warmed up, but the washing process itself does not occur. In this case, the likely causes of a dishwasher failure may be:

You can determine the failure of the circulation pump by the characteristic sound of its operation. If there is no noise after filling the water, most likely the cause of the malfunction is in it! As you can see, the replacement is not difficult.

It should also be noted that possible malfunction dishwasher, there may be damage to the electric motor, or rather its winding. To make sure the engine is working, check it with a multimeter for an interturn circuit and an open circuit.

Water overflows

Most likely, the water level sensor is broken. It is located at the very bottom of the equipment, so to access it will be necessary to turn the dishwasher over, and then replace the sensor with a new one.

We draw your attention to the fact that if the power is turned off and water is poured into the chamber, then the problem is not in the sensor, but in the solenoid valve, which should shut off the liquid supply. Replacing the valve is not difficult.

Overheating / underheating of water

It also happens that the dishwasher overheats or, on the contrary, does not heat the water. In the first case, the temperature sensor breaks, which leads to overheating of the water, the formation of a large volume of steam and the shutdown of the equipment.

As for underheating, there may be several reasons for the malfunction:

No drain occurs

If, after washing, the water does not drain into the sewer, then the pump may be broken or the drain system is clogged, which is why the dishwasher does not drain the water.

As for the first case, here you need to check the drain pump for debris and winding resistance. Most likely, the water is in the dishwasher due to the fact that the pump is simply clogged, although sometimes the start may not even occur due to pressure. If the pump is in order, check the entire drain system, including the siphon. Most likely, the hose is clogged, which just needs to be cleaned, or the filter inside the chamber.

There is another common case when the dishwasher does not completely drain the water. You're probably pushing too hard here. drain hose and after draining (when the pump turns off), part of the water returns back to the chamber.

Video instruction for cleaning the filter

The body is shocked

If the dishwasher is energized, then with a probability of 99% it can be argued that the heating element is broken - the heating element. All you need to do is open access to the heating element and visually inspect it for cracks and other kinds of defects. If the heating element is indeed damaged, replace it with a new one.

The reason why the heating element fails is poor water quality (too hard). Also, another malfunction may be the failure of the relay for turning on the heating element. The instructions for replacing the part were clearly demonstrated in the video:

Change the relay on the control module

Doesn't pick up detergent

If you notice that the dishwasher does not pick up the powder or tablet, the most likely cause of the breakdown is the contamination of the nozzles or the weak pressure of water, as a result of which it does not enter the dispenser. Also probable cause there may be a breakdown in the opening mechanism of the valve from which the detergent is washed out. If the valve does not open the water intake (or does not close well), the tablet may not dissolve completely, as a result of which the equipment does not rinse the dishes well.

Lack of power

If you notice that the time indicator does not even light up or the appliance does not respond to pressing the button, then the causes of the dishwasher malfunction may be as follows:

• broken socket;
• the door latch did not work, or the locking device burned out;
• network button does not work;
• network filter is not working.

In all cases, you need to check all elements with a multimeter electrical circuit and using the elimination method to find why the dishwasher does not turn on. If in your case the dishwasher does not finish the cycle or you cannot switch the program, check the programmer and control unit, most likely the modes do not work due to its malfunction.

extraneous noise

Extraneous noise indicates that the bearings of the pump or the electric motor (supercharger) have been damaged. Bearings break due to the fact that water enters them, which in turn seeps through a damaged seal. Bottom line - the dishwasher is buzzing during operation. In this case, you will need to not only replace the bearing, but also the oil seal itself, otherwise the same problem will occur again after a while. By the way, another reason for extraneous noise may be associated with the pump - debris got into the area of ​​\u200b\u200bthe sprinkler or impeller. Everything is simple here, remove debris and check the impeller for defects (perhaps the blades are already damaged, which causes noise).

Dishes are not drying

Some modern models equipped with the function of drying washed dishes. This process occurs when the fan installed inside the chamber is running. If you find that the dishwasher does not dry the dishes (or does not finish drying), but otherwise functions normally, the fan is most likely broken. All you need is to check its winding, as well as the supply contacts with a multimeter, and if necessary, replace the spare part with a new one. About that, we talked about in the corresponding article.

Water leaks on the floor

And finally, one of the most popular dishwasher failures is the flow of water onto the floor under the body.

There are four main causes of leakage:

• The door seals are in poor condition, causing the door to close loosely. They need to either be changed, or, if possible, cleaned of plaque.
• The seal of the pump that pumps water is damaged. It is best to replace with a new one.
• Clamps on the drain and water supply hoses are loose, resulting in leakage. Also, seals may not be installed at the junctions of the branch pipes.
• Damaged water tank located on the side of the equipment. Most often, the tank cannot be repaired, so it is changed to a whole one.

To correctly determine the place of water seepage, it is recommended to remove the casing of the equipment and place sheets of newspaper on the floor. Where the newspaper gets wet and there will be a breakdown.

Video tutorial on fixing leaks

That's all the main malfunctions of dishwashers. We hope that now you will be able to repair the equipment yourself if it stops working, starts to make noise or does not drain water after washing dishes.

Material

The dishwasher is not complicated, a number of maintenance actions have been developed that can be performed independently by the owner of the acquisition. Filter cleaning, adjustment. We hope the tips below will help you repair dishwashers with your own hands.

How does a dishwasher work

A number of standard operating modes are laid down, each model is equipped with a pair of specific ones. But the indicative algorithm is similar. The dishwasher draws water using the central network. The sampling goes through a salt softener by overflow. The brine compartment is usually located in the floor of the dishwasher, covered with a lid.

The flow enters under its own pressure, bypassing the inlet filter, and is regulated by a float valve or pressure switch. The required amount of water has filled the dishwasher - the supply channel is blocked, heating starts.

Depending on the technological stage of the cycle, the required temperature is different. For the last rinse, the value is traditionally increased. Designed to facilitate the process of drying dishes.

The heated water is pumped by the main pump (called the pump unit) into the working chamber. It gets there through sprinklers equipped with sprinklers. A well-thought-out choice of the direction of the striking jets creates a reactive force that rotates the impeller. The dishwasher has two spray arms - a lower and an upper. The design of fundamental differences is devoid of.

Waste water goes through two stages of purification, bypassing filters, and then used for washing again. During the described process, a little powder is introduced into the chamber through the door of the detergent drawer. The exact amount is set by the program. The dishwasher uses water several times, cleaning the flow with two filters, and at the end of the technological stage sends it to the drain with a special drain pump.

Drying is carried out at the end of the cycle. The procedure of several varieties, mainly:

• condensation drying;
• turbo dryer.

In the first case, the dishes dry due to the heating obtained by the last rinse, the steam condenses on the cold walls and flows down. The process is catalyzed by special substances contained in rinse aid, which reduce the surface tension of water. In dishwashers equipped with a turbo dryer, hot wet air is forcibly expelled by the fan to the outside, speeding up the process.

It was mentioned above how they get into the compartment washing powder, gel, tablets. The rinse aid is poured into a separate container, in some cases it may not participate in the process at all. The cycle looks like this:

1. prewash;
2. main sink;
3. rinsing;
4. drying.

It remains to be mentioned that for washing the dishes are laid out in special baskets, they lie motionless during the cycle. Jets of water pour from all sides due to the rotation of the sprinkler impellers. The following are a kind of dishwasher repair manual, good advice to monitor the correct operation of the equipment.

Repair of industrial dishwashers is recommended to be entrusted to professionals, what to do if the home model is stubborn, we will consider a little lower. We see a number of typical signs that manifest themselves in unsatisfactory appearance dishes after washing, which are not considered manifestations of breakage:

1. White stains, streaks covering the dishes indicate: not enough rinse aid or salt. All in 1 pills sold are powerless to guarantee impeccable quality. On the contrary, they are designed for the easiest possible use of the dishwasher in a limited time. The use of tablets will reduce the consumption of salt, rinse aid (if there is support for saving money by the machine), and not completely exclude funds from the work cycle. In this case, we will try to increase the dosage of substances. To be more precise, turbidity will serve as signs of excess rinse aid, streaks - a disadvantage.
2. It is recommended to clean the filters after each procedure. Located in the bottom area of ​​the working compartment, where the drain. By the way, you see: the water refuses to leave, floods the bottom, first of all it is recommended to do the same. Previously, removing the liquid from the compartment. There is no other choice, you can do this. The power is turned off, the water supply hose to the dishwasher is disconnected from the water supply valve. First, of course, block the pressure. Water will easily drain into a basin on the floor if you place the end of the hose there.
3. Dried pieces of food will remain. Dishwashers are characterized by such a feature: the devices do not cope well with burnt food. Soaking won't help. Burnt food must be scraped off by hand. We list five reasons for this phenomenon:
   1. Positioning the dishes prevents the jets from reaching the surfaces freely.
   2. The rotation of the impeller is blocked by a knife, a fork, which blocked the path of the rotation trajectory.
   3. There is no detergent, or the tray door is blocked by incorrectly placed dishes.
   4. Dishwasher impeller nozzles clogged. Needs to be cleaned. After removing one by one, perform under running water. The impellers of the dishwasher are fastened with a plastic nut, sometimes equipped with a left-hand thread. The top can simply be removed by turning.
   5. The trivial wrong choice of the program often causes the result of washing, to put it mildly, leaves much to be desired. Changing the dishwasher mode will fix the problem.
4. Too much foam means: too much rinse aid is being used. It is recommended to adjust the dishwasher dispenser accordingly or pour in more powder. The latter has a defoaming effect.

Procedure went astray

Each owner has seen enough of the kitchen assistant, so they are aware of how the equipment should work. Below are typical situations that signal minor malfunctions, simply calling for a do-it-yourself dishwasher repair.

• Extraneous knocks are heard. It is necessary to stop the process, check the correct loading of dishes. Plates, knives should not interfere with the impellers, the door of the detergent tray, and other moving parts. It happens that when washing, poorly fixed dishes beat against each other. The matter becomes more serious when the part is replaced with a new one, for example:

1. Impeller bearings damaged. Determine by rotating each hand. There is no knock, an additional test requires tying in turn, immobilizing, putting the machine into operation to try to identify the source of the malfunction.
2. A knock appears from time to time, you need to detect the moment of the onset of the event. The bearings of the main, drain pumps of the dishwasher can knock. The first works periodically, the second - at the end of each cycle.

• Dishwasher does not turn on. In a third of cases, they forgot to supply power to the device, or the fuse burned out. The first launch occurs, we see a chance: in collapsible fork wires wired incorrectly. If the fuse is blown, it’s too early to rejoice, it indicates an increased current consumption of the dishwasher. In addition to the above, there is whole line auto-locks:

1. The door is not tightly closed. Each owner of an automatic washing machine knows: does not erase until the lock snaps into place. The kitchen uses something similar to eliminate the possibility of water overflowing onto the floor. Make sure the door is closed.
2. Water does not reach working chamber. Caused by a closed faucet, the inlet filter is clogged, less often the problem is with the hose. It is easy to check by first closing the outlet valve central water supply, substitute a basin for the hose, carefully open the valve for a short period of time. Inspection of the intake filter. The accessory can be carefully removed with pliers, rinsed thoroughly with tap water. Then insert back into the inlet of the dishwasher.
3. Faulty programmer. Workshop dishwasher repair will help. We leave the option for last. A faulty programmer causes a variety of problems.

• Dishwasher seems to work, but no water enters. It’s worth starting with the previous paragraph, inspecting the hose, filter. The reason may turn out to be more prosaic, unpleasant: the intake valve has broken. The accessory is relatively easy to change, you have to buy a new one. The part goes after the intake filter. You will need to disassemble the case.
• Pressure switch defective. We disconnect the element from the wire terminals, slightly blow the pipe, to which the plastic tube fits. When the device operates satisfactorily, a slight click is heard.
• The machine stopped in the middle of the cycle, the case, in addition to the fuses and the availability of power, concerns a faulty working pump. First check the recirculating water filters. When slaughtering, the dishwasher will behave in a similar way. The water intake path (see above), the heating element, and the thermal relay are faulty.

• The slow filling of the dishwasher with water is caused, in addition to the slaughter of the inlet tract, by the insufficient pressure of the water supply.
• The water stopped heating up. In addition to the obvious reasons - breakdown of the thermal relay, heating element, - it's a pressure switch. Incorrectly determines the water level, gives false commands to the dishwasher.
• The door stopped closing. Check the balance spring. In 90% of cases, the cause is found.

Conclusion

Whether it is the repair of built-in dishwashers, the repair of Kandy dishwashers, the process takes place along the same technological route. It is important to understand: external differences household appliances do not mean internal differences.

A dishwasher is one of the main helpers in the household, which, in the endless household bustle, saves you from unpleasant and demanding labor, and some time washing dishes. That is why, when the dishwasher suddenly does not work for some reason or some kind of malfunction occurs, this is a reason to worry and call the master at home, and sometimes go to the service center. What can cause a breakdown and how to deal with it?

Causes of dishwasher failures

Unfortunately, even the most wear-resistant and durable dishwashers, such as Bosch (), Indesit, Veko, Electrolux and others, can break down. The following reasons may contribute to the appearance of malfunctions:

• fluctuations in electricity ("jumps");
• water characterized by hardness, that is, saturated with various small particles, for example, salts;
• low-quality household chemicals that are not suitable for the dishwasher;
• neglect of the rules of operation and;
• improperly installed dishwasher.

Basically, the dishwasher breaks down not due to malfunctions of some parts and mechanisms, but due to clogging of various filters, contamination of parts, build-up of scale or adverse external factors(“voltage surges”, weak water pressure).

Therefore, be sure to carefully study the operating instructions in order to. In addition, knowing how it should, according to some indicators, you can independently understand what kind of malfunction occurred and why the work process was suspended. So, if the icon in the form of a lock is displayed, this indicates that the door is not closed tightly, therefore, in order not to flood the room.

The dishwasher works by interacting with many different factors, therefore it reacts sharply to changes in external factors, thanks to sensors such as temperature, that is, a thermostat, water level, that is, a pressure switch, pressure, water purity, and much more. If suddenly there is a breakdown of the sensor itself, then the operation of the dishwasher may be suspended. Since the sensors operate in dirty conditions, they often become dirty and, as a result, break.

If a breakdown occurs and the Bosch dishwasher does not work or the Indesit machine does not turn on,. The only thing is that for this you need to know how the sensors interact, how the process of washing dishes takes place, and you also need to know thoroughly internal structure dishwashers.

The structure of the dishwasher and the principle of the washing process

A powerful stream of water has tremendous power, so good pressure is the main factor that ensures cleanliness and shine of dishes, washing away food residues.

The dishwasher is made in such a way that it is possible to provide the necessary pressure of water, which will allow not only to qualitatively wash off food residues and dirt from the loaded dishes, but also will take care of it without leaving any damage. Due to the fact that it is necessary to wash very large area, then several jets of water were made that evenly clean plates and other dirty dishes.

In order to achieve maximum cleaning, special devices (“rocker arms”) are built into the dishwasher. They use nozzles to spin jets of water.

Poor cleaning of dishes

AT recent times more and more often you can meet complaints from owners of dishwashers that the equipment cannot fully cope with its work, and it needs repair, because at the exit, and therefore it needs to be washed manually. The reasons for this may be different: the wrong mode was selected that is needed, or the water temperature is not up to standard, breakdowns of internal parts of the equipment.

Besides important point there is that if the pressure of the water jets is not strong enough, the food remains will not be washed away in the time allotted for the dishwasher. Also, the reason may be an insufficient number of jets produced or their speed will be insufficient, which means that the thrust will not be able to make the rocker arms rotate enough, as a result of which, some area of ​​dirty dishes will be uncleaned.

The reasons for the insufficient pressure of some jets may be the following:

• nozzles clogged with debris;
• clogging in the filter area, as a result of which not enough water enters the pump;
• such a part as the impeller of the pump wears out, which does not produce the necessary pressure;
• wear of one or more bearings or failure inside the motor, resulting in a decrease in the number of revolutions.

You can clean the nozzles with your own hands, moreover, it does not require opening the dishwasher case. It is enough just to remove one or another rocker and gently clean the nozzles with a toothpick or needle.

Bosch dishwasher filters not working: repair work

Each technique for cleaning dirty dishes, for its own effective work requires periodic cleaning of filters. Dishwashers from different manufacturers have a correspondingly different internal structure, and therefore, for competent and accurate cleaning of filters, you must first carefully read the instructions, which describe in detail the cleaning rules. An indication that the filter elements really need to be cleaned is the accumulation of liquid in the dishwasher or even its leakage through a tightly closed door.

In order to completely clean the filters, first of all, you need to get a special filter from the dishwasher. metal carcass where the dishes are usually located during the operation of the equipment. The filtration system consists of several different sections. Above is a coarse filter in the form of a plate, below are filters with small cells. A layer of fat builds up on a fine mesh filter.

If the filter is dirty, the pump pumps out less water than necessary, which reduces the pressure, so the dishwasher increases consumption due to water from the water supply. Excess water settles on the bottom of the dishwasher and sometimes leaks through the seal.

Highly important factor in the process of competent operation of the dishwasher is the use of salt. , which contributes to the elimination of grease in hoses and various machine parts.

Prospects for alleged repairs

There are also cases when, after thoroughly cleaning the filters, the dishwasher refuses to work in normal mode. To understand what kind of repair is needed, you must first find out what the problem is and what kind of breakdown occurred. To do this, it is important to understand which washing step was interrupted or skipped altogether.

If the operation of the dishwasher was suspended at any of these stages, then a breakdown occurred in the part responsible for this function or action.

We get acquainted with the codes of malfunctions and errors

Most modern equipment and technology that are equipped with a microprocessor can identify an internal breakdown using special error codes. Therefore, in order to understand what kind of breakdown occurred, you need to carefully study the instructions. So it is quite possible to diagnose a malfunction without resorting to disassembling the dishwasher body. Why can a working dishwasher not do its job well, why did the signal not work and show an error?

Here are the main breakdowns and the reasons why the dishwasher does not work:

• there is no water intake - a malfunction with the electromechanical valve (perhaps the valve is jammed, or its coil is burned, there is a possibility of a malfunction of the electronics);
• washing liquid is not taken from the compartment - switched on wrong mode, perhaps the tubes are dirty, the valve has broken or the algorithm of actions has gone astray;
• the rocker with nozzles has stopped rotating - the pressure is below normal, the nozzles are dirty, the accumulation of a layer of fat, scale and dirt on the surfaces that are involved in friction;
• sudden stop of the machine - the filters are clogged, the engine is overloaded, the algorithm has gone astray, it is also possible that the safety pan that collects leaks is full;
• water does not drain - there is a malfunction in the pump, filters are clogged or air pressure is observed in the sewer, which interferes with draining.

In fact, there can be many more of these reasons, and all the necessary information about the nature of the breakdown, the reasons for its occurrence and how to eliminate it should be described in the instructions.

The dishwasher does not work: DIY repair

First of all, it is necessary to start troubleshooting with great care. This item is very important, because trying to fix it is not known what kind of damage is not the most best idea, on the contrary, it can aggravate the situation. If the source of the dishwasher’s malfunction or its malfunction is determined, then you can proceed to self-repair. To do this, you need to have a certain set mounting tools. Ordinary, curly, Phillips and hex screwdrivers, wrenches different sizes and pliers.

First, be sure to push the dishwasher out, look for niches so that you can get to all its details and from all sides.

A very important point that in no case should be ignored: it is necessary to disconnect the dishwasher before proceeding with the disassembly of the case and repair of parts in order to avoid electric shock.

Experienced craftsmen when they start repair work, start by looking for minor breakdowns that are easy to fix and fix. These include an unimportant contact, a failed cable, a connection that has succumbed to oxidation, and so on. When diagnosing electronic systems, this option is also possible and even recommended. First, you should carefully examine everything in order to correct the damage caused by exposure high temperature, electric arc, if any.

Further, after fixing simple breakdowns, it is necessary to identify Problems with those parts that are responsible for the operation of certain functions of the dishwasher. So, with the help of multimedia, you can check the coils solenoid valves, relays, semiconductor components, sensors, ring an electric motor, measure voltage, and more.

In one article, it is difficult to describe all types of breakdowns and malfunctions that may occur in a dishwasher of various manufacturers and brands, indicate all the reasons that contribute to the failure of the dishwasher, and ways to solve these problems. If suddenly you are faced with something similar, first of all carefully study the instructions, you will find the answer to many of your questions there. In addition, you can easily find any information on the Internet, now there are a lot of sites and forums where experienced specialists and home craftsmen can use their tips and skills to repair various household appliances, including dishwashers.

Even if this does not help and the reason why the dishwasher does not work is not determined, then the most best solution will call the master to the house. He will not only determine the cause of the breakdown for sure, but also quickly eliminate it. In this case, you can be sure that the dishwasher will not break again after a few days.

In general, try to treat the dishwasher with care and attention, follow all the rules for operating and caring for it, which are indicated in the instructions, use a high-quality household chemicals. This will not be difficult for you, but on the contrary, it will make your life easier, because then you will forget what a dishwasher breakdown is. Take proper care of household appliances not difficult - it is difficult to repair it later, and sometimes, unfortunately, it is even impossible.

Dishwasher - quite expensive, but really useful attribute kitchen appliances which can make housework much easier. If every time you encounter a problem, contact the master or the service center, its content will cost a pretty penny. But in most cases, dishwasher repair can be done by hand.

In order to identify the causes of a malfunction, you need to understand how dishwashers work. All of them have standard set functions and details, with differences in some additional options.
Dishwasher device (PMM):


How PMM works:

• The dishes are fixed in separate compartments in a special basket;
• The electric motor drives the circulation pump, which delivers water pressure through the hose to the impellers (they are also called "rocker");
• Water is heated using a heating element (electric heater);
• "Yoke" sprays powerful jets of water on the dishes, thereby cleaning them;
• Used dirty water, flowing down, goes through a two-stage cleaning system and is reused in the washing cycle;
• At this stage, a special compartment is filled with right amount rinse aid entering the water towards the end of the cycle;
• At the end of the cycle drainage pump dumps dirty water;
• Drying is done by two different ways, depending on the brand of dishwasher. It can be provided by condensation of steam from heating during the last wash cycle (condensation dryer), or by using a fan that expels hot, moist air from the machine (turbo dryer).

Thus, the PMM alternately performs a preliminary wash, main wash, rinsing and drying of the dishes loaded into it.

Common causes of breakdowns and methods for their elimination

When using a dishwasher, there are often problems that we can fix ourselves or with the help of a specialist. Many models of dishwashers have a built-in display on which an error code is displayed in case of a malfunction. You can decrypt it yourself using the instructions, or if it is not preserved, this information can be found on the manufacturer's website. Code analysis will help identify the cause of the breakdown before disassembling the machine body. What are the most common faults?

In most cases, this is due to a faulty balancing spring. Replacing it will solve the problem.

There is a rattling noise while the machine is running.

If this problem is detected, stop the washing process and then check if the dishes are placed in the basket correctly. Extraneous sounds may occur due to the fact that poorly fixed dishes beat against each other, against the walls of the machine, rocker arms or other moving parts.
If you are convinced that the dishes are installed correctly, then the reasons for knocking may be as follows:

• Broken rocker bearings. To identify this problem, you can twist each of the impellers and listen to the sound they make. If knocks do not appear, you can conduct another test: immobilize these parts by tying, turn on the machine and try to determine the source of the sound;
• An intermittent sound may indicate damage to the bearings of the main or drain pumps. In the first case, the sound will appear several times during the washing cycle, in the second - at the end of the cycle.

Both problems are solved by replacing damaged parts of the dishwasher.

Machine runs but no water enters

Here again you need to pay attention to the hoses and the filter. If it turns out that both parts are in order, then the cause lies in the intake valve. It is located immediately behind the filter, and in this case, the repair of the dishwasher will consist in replacing it.

The machine does not turn on

Each dishwasher has a number of automatic locks that are triggered if:

• The PMM door is not closed tightly;
• No water enters the working compartment. In this case, it is worth checking whether the tap is open, the integrity of the hose and the degree of contamination of the filter. The filter is recommended to be cleaned after each wash;
• Broken embedded programmer. This breakdown is already quite serious, and you won’t be able to cope with it on your own - you need to contact the master.

Another serious reason why the dishwasher does not turn on can be a blown fuse. It is not enough to eliminate such a breakdown, since initially the problem most likely lies in the increased current consumption of the machine.

Pressure switch failure

One of the options for correcting this malfunction is to disconnect this part from the wire terminals and blow into the pipe with a plastic tube. At correct work device, you will hear a soft click.

PMM stopped working during a cycle

If everything is in order with the power and the fuse, then the problem may be:

• In a malfunction of the working pump. In this case, you must contact the master;
• In the contamination of the filter used to purify recirculated water;
• In the breakdown of the water intake path, thermostat or heater. It is not possible to fix these breakdowns on your own.

Water fills slowly

Most often, the reason lies in weak pressure tap water. You need to wait until the pressure becomes optimal for quality work dishwasher.

Water does not heat up

In addition to what may turn out to be a broken heating element or thermal switch, the problem may lie in the pressure switch. This part may erroneously detect the water level in the machine and give it the wrong command.

Causes of poor-quality cleaning of dishes by a machine

In addition to malfunctions in the operation of the dishwasher itself, you can often encounter poor-quality performance of its cleaning duties.

Divorces and smudges on the dishes

Such marks may remain due to insufficient rinse aid or salt. This problem often arises when using all-in-one PMM tablets, which do not preclude the use of additional water purification and softening agents. Increasing the dosage of rinse aid or salt will solve the problem.

Dried pieces of food

The main reason for the dishwasher to leave such contaminants is burnt food. In this case, even pre-soaking will not help, so you will have to scrape off the burn yourself. In addition, there are several other reasons for poor cleaning of dishes:

• • Incorrect placement of dishes, as a result of which water jets do not reach all surfaces;
  • The impeller stopped rotating due to blocking it cutlery or other utensils;
  • There is no detergent in the tray;
  • A tablet of the wrong type for PMM was used. Not all machines are designed to use three-in-one, all-in-one products - they should be bought according to the instructions;
  • The lid of the tray did not open due to an inaccurately placed and pressed item of dishes;
  • There is a blockage in the impeller nozzles. Carefully removing the fasteners, the impellers must be removed and cleaned with running water;
  • Wrong program selected. It is necessary to set the operating mode of the PMM, following the attached instructions.

Most of the above problems can be avoided by properly and carefully operating the dishwasher.

• First of all, you need to remember that all programs in this technique are automatic, and any deviation from the instructions can lead to a serious failure. Therefore, all modes additional functions should only be used as directed. As a last resort, refer to the PMM manufacturer's forums.
• The process of cleaning dishes in the machine is carried out not only by pressure hot water, but also different chemicals- cleaners. Using quality products will extend the life of your machine.
• It is enough to carry out a thorough cleaning in the dishwasher once every few months to avoid many malfunctions. Clusters should be removed detergents, sediment of salts and calcium. Including it is necessary to periodically clean the filters, hoses, the lower pan of the machine.
• Load the dishes into the machine correctly. Large objects should not block water jets, pinch covers, valves and impellers. Water should not accumulate in deep plates and cups. Silver appliances should be securely fastened.
• Do not allow scale to form in the dishwasher. You can clean it up with special means descaling by running a cycle with them without dishes as many times as necessary for cleaning.
• If rust forms on the PMM case, replace these parts or eliminate corrosion with enamel or paint. Replacing the housing is much cheaper than replacing rusted internal parts. A clean car will increase its service life by several times.
