Dishwasher does not rinse. Causes of breakdowns and repair of dishwashers

13.05.2019

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 have already Dishwasher out of order, 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 dishwashers do not rinse completely, as a result of which you have to additionally rinse by hand.
Socket failure. A banal situation but still sometimes arises.
Wrong (for example, length drain hose greater than the permissible value or a 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). Another important requirement is that glasses and cups must 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:

Determine failure circulation pump possible by the characteristic sound of his work. 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 a possible malfunction of the dishwasher 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. Here, most likely, you pulled up the drain hose too much 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, a probable cause may be a breakdown in the valve opening mechanism, 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 the elements of the electrical circuit with a multimeter and find out by elimination 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 Bosch concern is responsible for the quality of its products. Indeed, German technology is distinguished by reliability and high-quality assembly. But this principle only works if the operating conditions are observed. In our conditions, it is not always possible to follow the instructions. The quality of water and food in the network leave much to be desired. In the event of a Bosch dishwasher malfunction, you can contact the service, or you can do the repair yourself.

Common causes of Bosch dishwasher breakdowns

If problems with work began after buying the machine, pay attention to the settings. Is the work well organized? The correct connection of communications, inlet and drain hoses is important.

What breakdowns happen most often:

Appliance won't start. The indicators on the panel do not light up, the system does not respond to key presses.
Aquastop protection is activated. The reason is water leakage into the pan or a malfunction of the float sensor.
Water not draining or taking in. The point is clogged filters, paths. Malfunction of the circulation pump or pump.
Program freezes after washing starts. Clogged water inlets, breakage electronic control. It is also possible that the sunroof lock may be defective.

Problems may be manifested by an error code on the screen. The electronic board is connected to all nodes by means of wiring. If one of them does not respond, does not respond to signals, self-diagnosis starts. You will find the decoding of the code in the instructions or in the publication " Bosch dishwasher error codes.

Main fault codes:

E01 / F01 - electronics failure, breakdown on the heating element body.
E09 / F09 - the operation of the heating element is disrupted.
E3 / F3 - water is not poured into the bunker.
E22 / F22 - clogged filters.
E24 / F24 - E25 / F25 - problems with draining the used fluid.
E15 / F15 - the Aquastop system has worked.
E27 / F27 - power surges in the network are fixed.

Some problems are fixable by hand. Do not rush to immediately call the master, figure out the reason for the breakdown of the dishwasher. If, after eliminating blockages and errors, the machine does not start normal operation, then proceed with the repair work.

How to fix a dishwasher yourself?

There are two typical problems for Bosch PMM models. They are associated with water. Often users complain about the appearance of the E15 code on the display. This indicates the operation of the Aquastop protection. But it's not always a leak. Follow these steps:

Tilt the PMM body back and look into the pan.
If there is really accumulated water - drain it.
Return the float switch to the off position.

Sometimes the cause of the operation is the incorrect placement of the inlet hose gasket. It may have moved during installation. Therefore, make the connection following the user manual.

Dishwasher won't turn on

Have you connected the machine to the network, pressed the Power button, but nothing happens? The lights on the panel do not light up, no beeps are heard. What to check:

Network wire. Sometimes it bends if, during the rearrangement, it is pressed against the body of the dishwasher. If you notice damage to the insulation, do not do homemade twists. This approach can lead to a fire. Replace cord immediately.

Fork. The presence of melting and burns indicates a breakdown. Install the correct item.
socket. To check its performance, connect another device. Works? So the outlet is correct.

It is worth checking the mains filter (capacitor). It is located near the engine. On visual inspection, swelling and burns should be alerted. The part is to be replaced. You can buy it cheaply in the online store.

Leave the problems with the electronics and the control unit to the master. Here you need an accurate diagnosis, which is carried out with a multimeter.

Water intake and drainage problems

With such a problem, simple carelessness should be excluded. So, it's worth checking out:

Is the stop valve open. Perhaps it was accidentally blocked.
Is the inlet hose straight? If it is bent, pinched by a foreign object, water will not flow.

When installing a hose with Aquastop protection, you need to monitor its operation. When the system is triggered, the absorbent is saturated with moisture, which blocks the passage. This is a one-time protection, so you need to completely change the hose.

It is important to service your dishwasher at least once every 1-2 weeks.

Maintenance includes cleaning the system of debris:

Shut off the water supply.
Disconnect the hose from the housing.
Take out the mesh filter.

Rinse it clean.
Check intake valve operation. Examine its holes. If debris enters, the passage becomes clogged, which makes it difficult for the membrane to move. It does not open, and the liquid does not flow.

With problems with draining, the pump does not necessarily break. Check parts for clogging:

Open the chamber door.
Take the baskets out of the bin.
There is a filter at the bottom.

Unscrew and clean the part.
Check pump impeller. Pieces of food passing through the filter can block its rotation.
Remove water from the hole.
Remove the cover by pulling it towards you.
Put on gloves, remove blockage.

How to check the pump:

Disconnect the device from the network and communications.
Lay a towel on the floor.
Turn the PMM case on its side.
Remove the bottom panel.
In Bosch dishwashers, the pump is assembled with a heating block.
To replace, disconnect the terminals from the pump, scroll and remove it.

This video describes in detail the pump device and the principle of its replacement:

Wash does not start

In such cases, the machine turns on, the indicator lights up, but the wash does not start. Or the program freezes. What is the reason and how to repair the equipment:

System failure. If the dishwasher does not work normally after a power outage, restart it.
The machine door is not closed tightly or the lock is faulty.

Let's analyze the last problem in more detail. The lock secures the door electronically. A tightly closed door should click, after which water intake and washing begin. Press it tighter. If the lock does not work, it must be replaced.

Open the dishwasher door.
Remove the screws from the inside.
Open the outer panel.
Disconnect the lock wiring and install a new element.

Closing problems can also occur for the following reasons:

Deformation of the sealing collar. Replace seal.

Incorrectly placed utensils. Check the arrangement of objects in the chamber, push the trays deeper.
Dishwasher housing not level. PMM should be located on a solid flat surface, strictly by level. Tilting the cabinet may cause the door to not seal properly.

Blockages in the filling path lead to the suspension of the PMM. Purge the systems for normal water flow into the hopper.

We have listed the problems that are most common in Bosch dishwashers. Due to their popularity, service center visits are higher than other brands. But now you know that many problems can be fixed by hand.

Repairing a dishwasher often becomes a problem for many housewives who have a similar unit. The main difficulty in this situation is the lack of understanding of how serious the breakdown is and whether it is worth calling the master, or everything can be done by hand. As practice shows, most often independent analysis turns out to be effective. In addition, machines from such well-known manufacturers as Ariston, Bosch, Siemens, Electrolux notify of malfunctions. special code, allowing you to find out exactly the cause of the breakdown.

The device of the machine and how it works

In order to accurately understand the cause of the malfunction and not only how to fix it, but also how to avoid it, let's try to briefly understand its structure. Appearance A device may give the impression of internal simplicity, but in reality there is a complex system of regulators, sensors and other controllers hidden there. It is known that, according to the form factor, dishwashers are freestanding and built-in. Repair of the latter is somewhat more difficult due to difficult access to the necessary mechanisms. Of course, this is an even bigger problem when repairing with your own hands.

In general, regardless of the form factor, the dishwasher works according to the following algorithm:

The user sets the operating mode using the control panel (temperature, pressure, water flow, etc.) and loads the dishes.
After closing the door in the machine, the contact closure sensor will work and the water supply will turn on. Hot water can either be supplied from house communications or a boiler, or heated by a heating element built into the apparatus.
After a set, the sprayers installed at the top of the working chamber begin to spray water onto the dishes. This process is controlled by a special valve.
After washing dishes drainage system pumps out soapy water and the rinse mode is activated.
The wash cycle is completed and the door opens to unload the chamber.

On the this principle the operation of machines of almost all reputable brands is based: Ariston (Ariston), Hansa (Hansa), Elenberg (Elenberg), Ardo (Ardo), Bosch (Bosch), Siemens (Siemens), Candy (Candy), Beko (Veko), Electrolux ( Electrolux), NEFF, etc. The presence of additional modules and washing stages is determined by the functionality of the machine (for example, blowing or additional cleaning), but the described order is the basis.

Causes of dishwasher failure

This section deals with situations where a machine stops working that has worked less than 5 years or its warranty period, because in this case the cause of the malfunction is most likely the normal wear of one of the modules.

If the dishwasher was purchased relatively recently and does not have, so to speak, high mileage, the reasons may lie in the following:

Poor quality parts or assembly. This is a common diagnosis of devices purchased from Chinese or little-known manufacturers in order to save money.
The user loads dishes with large food residues clogging the filter. It also happens that the machine does not wash heavily soiled dishes well and the plates have to be washed and rinsed by hand.
Unsatisfactory condition of the electrical network or outlet. It is not related to the machine itself, but often occurs due to ignoring the special requirements for powering equipment.
Incorrect installation of the device. For example, the water supply hose is loose or the drain hose is longer than necessary.
Inappropriate or poor dishwashing detergent.
The reason that the dishwasher does not draw water may be that the door is not closed tightly. Because of this, the contacts that start the washing cycle do not close.
The machine may not wash dishes well due to improper loading. To avoid situations when the device cleans only part of the items, you need to study the loading rules in the user manual.

With the exception of the first point, the problems described here can only be considered relative malfunctions that are not related to breakdowns. Most of them, any housewife can fix with their own hands. In the future, we will focus mainly on breakdowns of internal modules and on situations where it is impossible to restore functions without penetration into the device.

If the car wash does not start

This happens approximately as follows: after setting up the cleaning program and loading the dishes, you closed the chamber, the machine took in and heated the water, but the washing process does not turn on directly. The reasons for this may be the following malfunctions:

Often this is due to a clogged drain filter under the chamber. The problem is easily solved with your own hands - you need to turn off the machine, pull out the filter and rinse thoroughly.
Water is poorly sprayed or not sprayed at all due to clogged spray nozzles. Due to clogging of these holes, the water pressure can drop noticeably, which causes poor washing of pots. The nozzles are easily cleaned with a toothpick, but if the rocker itself does not spin, then the cause should be sought in the circulation pump, which is often broken down in this situation.
If the circulation pump breaks down, water collection becomes technically impossible. This malfunction is considered one of the most difficult, but is solved by simply replacing the part. Those who plan to do it themselves should know that in order to gain access to this node, you need to unscrew all fasteners to the body and tubes. The pump itself is located at the bottom of the machine.

Problems with recruiting, draining and heating water

The reason that the machine draws too much water into the washing chamber is a malfunction of the corresponding sensor. In this case, you can also carry out repairs yourself. You just need to buy a similar device to replace it and install it in place of the broken one. The water level sensor is located at the very bottom of the machine.

If water enters the dishwasher that is turned off, the solenoid valve is faulty, interrupting the flow of liquid inside. Its replacement is also not particularly difficult, subject to the acquisition of a suitable model.

The machine does not completely drain the waste water into the sewer in cases where the corresponding pump is faulty or the drain system is clogged. In such a situation, you need to get to the drain pump, clean it of debris and check the resistance on the windings. If this does not help, you should check all the hoses of the drain system, the siphon and the filter located at the bottom of the chamber.

Often the cause of malfunctions of the drain system is its incorrect installation. This often occurs when installing washing machines– the drain hose rises too high and part of the water returns to the chamber after the pump is turned off.

Why does the machine turn on and start the cycle, but it generates a lot of steam and heats the water too much. In this case, the cause of the problem is a breakdown temperature sensor, which should stop the heating system. Some models automatically stop working at the same time. Replacing the sensor is also not a very difficult task.

The opposite situation - when the water does not heat up well - may be due to the following violations:

turning off the temperature sensor (heating does not turn on if the control system does not receive a signal from it);
with low water pressure on the nozzles or pump (the reasons are described above);
The heating element is out of order - checking its performance is carried out using a multimeter.

If the car is electric

Reason for admission electric current on the body of a person in contact with the body of the dishwasher is the penetration of the heating element. Voltage is transmitted through water when the integrity of the tubes of this element is violated. This occurs when the device is operated with too hard water, as well as when the internal switch fails. If the machine “beats” with current, you need to open it and examine the heating element for damage. If there are any, it should be replaced.

Detergent set

If the dishwasher does not pick up the cleaning powder or tablet during the washing process, it means that water does not enter the dispenser. As a rule, this occurs due to weak pressure. Another reason is the failure of the intake valve. It may close poorly or not open the valve at all, due to which the tablet or powder dissolves only partially.

Noise

The most common cause of extraneous noise during operation of the dishwasher is wear or damage to the bearings of the electric motor or pump. The failure occurs due to water entering the bearings, seeping through the stuffing box. The car starts humming. In this case, the bearings and seals must be replaced.

The reason for the appearance of noise during the operation of the dishwasher may be the ingress of debris into the spray arm or impeller. You need to get to them, remove debris and check the integrity of the impeller.

Possible causes of water leakage on the floor

The door of the machine does not close well due to the poor condition of the seals. They need to either be cleaned of plaque or replaced.
The pump pumping water has a broken seal and is leaking water to the outside. You can try to replace the seal, but replacing the entire device is more reliable.
The clamps on the supply or drain hose are poorly tightened or there are no seals at the joints of the nozzles.
Water tank damage. It is not possible to repair the tank, so it is simply changed.

Experienced craftsmen advise placing a newspaper on the floor to detect the exact location of the leak, after removing the casing from the unit. When the paper gets wet, the source of the problem will be immediately visible.

"Weaknesses" and breakdown codes of famous brands

Today, many dishwashers of well-known world manufacturers, even in the budget category, are equipped with automatic system diagnostics of violations and breakdowns. It uses codes - when a malfunction is detected, the machine displays the corresponding code. In addition, each manufacturer uses its own notation.

Electrolux

According to user reviews and the opinion of repairmen, Electrolux dishwashers often have a problem with water flowing onto the floor. This happens as a result of damage to the seals and the parts themselves through which the liquid flows. For signaling, the machines are equipped with a tray, when water gets into it, the i30 code is displayed on the display, and the LED starts flashing three times.

Error codes:

i10 - water is not injected into the chamber;
i20 - water draining is difficult or does not occur;
i30 - overflow or leakage;
i50 - short circuit of the triac of the pump;
i60 - violations of the heating system;
i70 - short circuit or open thermistor;
i80 - communication error with the firmware;
i90 - broken programming model;
iA0 - sprinkler blocking;
iB0 - the transparency sensor does not work;
iC0 - connection with the user interface is lost;
id0 - no signal is received from the tachogenerator;
iF0 - water supply time error.

Hotpoint-Ariston

Despite the fact that the Ariston brand is one of the most reputable in the household kitchen appliances market, it also has its own typical malfunctions that happen most often. Excluding cases with clogged filters and working mechanisms, it can be noted that Ariston often fails the heating element, because of which it either chooses plugs or does not wash dishes well. Also on the list of common faults: failure of the water level sensor, inlet valve and drain pump.

Ariston machines (Ariston) use the following coding system:

AL01 - the Aquastop system has tripped due to a leak;
Al02 - the flow of water into the tank is difficult or not carried out;
AL03 - difficult or impossible to drain;
Al04 - power supply of the temperature sensor is broken;
AL05 - water level sensor or circular pump is faulty;
AL06 - the power supply circuit of the filling valve is broken;
AL08 - an error signal is received from the temperature sensor;
Al09 - keyboard malfunction or electronic module program failure;
AL10 - the power supply circuit of the heating element is broken;
AL99 - no communication due to problems with the electronic module or cable.

Bosch

Typical malfunctions of Bosch dishwashers (Bosch) include:

The machine does not turn on when the water and power supply are correctly connected. Most often, the cause lies in a malfunction of the start button or door lock.
Leakage of water on the floor. Here, damage to the hoses, clogging of the filter, and failure of the level sensor are observed.
The device does not wash well due to low pressure on the spray arms. Often the problem is solved by self-cleaning.
Failure of the electronic control board. In this case, you cannot do without the services of a master - the block will have to be changed.

Error codes:

E01 or F01 - failure in electronics and electrics, quite often - damage to the heating element;
E2 or F2 - temperature sensor malfunction;
E09 (F09) - malfunction of the flow heater;
E11 (F11) - lack of power to the temperature sensor;
E12 (F12) - a large number of dirt or scale (some models, after a reboot, signal this error with code E09);
E3 (F3) - no water is drawn;
E5 (F5) - the tank is full;
E8 (F8) - the circulation pump cannot turn on due to the fact that the machine does not draw the required amount of water;
E16 (F16) - the dishwasher cannot stop pouring water into the chamber;
E17 (F17) - a narrow-profile error, saying that the intake valve does not close as expected due to strong pressure;
E21 (F21) - errors in the operation of the drain pump during normal power supply and the functioning of the sensors;
E07 (F07) - the hole through which water is pumped out is blocked (garbage or improperly placed dishes);
E22 (F22) - one of the filters is clogged;
E24 (F24) - water does not leave due to clogging of the sewer or drain hose, if the hose is kinked or the siphon is blocked;
E25 (F25) - clogging of the pump nozzle or drain hose at the base; E4 (F4) - the water supply control sensor is faulty or does not work properly;
E6 (F6) - the water purity sensor has broken;
E14 (F14) - the sensor for controlling the amount of water in the tank is not working correctly;
E 15 (F15) - an error occurs for models with the Aquastop system during a leak;
E27 (F27) - voltage drops in the mains, you need to connect the machine through a stabilizer.

Among the common malfunctions of dishwashers, the defect of poor-quality washing of dishes is common. What causes such a malfunction of the dishwasher? As the practice of repairing household dishwashers shows, the reasons for the appearance of such a defect can be different. Let's try to cover, if not all, then most of the faults, due to which the dishwasher does not wash dishes efficiently.

Apparatus for washing household dishes for household purposes - the technique is rather complicated. However, any level of complexity is built by separate simple mechanisms, parts, accessories. So let's start simple.

Top atomizer gasket

Poor washing of dishes may be due to low water pressure on the spray mechanism. And the reason for the decrease in pressure may well be the gasket of the nut that fastens the water hose to the nozzle of the sprayer.

This gasket is located inside the body of the mounting nut, which secures the rotating atomizer to the water supply pipe. The gasket may have simply lost its elasticity properties. Then the seal will have to be replaced.

The gasket of the dishwasher nozzle nut is often the reason for the dirty dishes to come out of the machine after going through a full washing cycle.

If it is decided to replace the gasket, make sure that after removing the old gasket, no dirt or debris remains on the surface for seating the seal. The presence of contaminants can cause a poor seal even with a new gasket.

Pressurized water sprayer

Dishwasher sprayers are conditionally divided into “designs by location” inside washing bath. In this case, depending on the model, one or more sprayers can be installed:

lower,
upper,
average.

These items can cause the dishwasher to not clean the dishes properly.

The function of the atomizers is to distribute evenly hot water under pressure on the dishes loaded inside the dishwasher tub. Make sure that the atomizer(s) rotates freely, the movement of the device is not slowed down by the loaded dishes.

Violation of the free play of the dishwasher atomizer also manifests itself in the event of bearing wear. If the bearing is worn or damaged, the atomizer vibrates and does not provide a proper water spray pattern.

Inoperability - low water pressure, a change in the direction of spraying may occur due to clogging of the spray holes. Such a malfunction is easily detected visually.

It is also necessary to inspect the dishwasher nozzle(s) for cracks or clogged body openings.

All kinds of food remnants, toothpicks, cellophane film, glass or other foreign objects can prevent the passage of water through the sprayer holes, which worsens the pressure force and spray direction.

The filter system of the mechanism, if any, should be checked. On a dishwasher with a top spray, inspect the sprayer mounting bracket to make sure it is not loose, which could cause correct work devices.

Medium sprayer dock

If the dishwasher has a middle spray attached to an adjustable top rack, check the dock along with its valves.

The docking station is located on the back wall of the dishwasher tub on the water connection. The docking station supplies water to the middle atomizer and usually has two outlets.

Checking the operation of the valves of the docking station. These components of the design of washing machines can also create conditions for poor-quality washing of dishes.

Make sure that the docking station is securely connected to water pipe. It is recommended to check the valves for free movement.

Valves must close tightly and prevent pressure loss. It is also recommended to inspect plastic parts for cracks and chips. Replace parts if necessary.

Dishwasher and food grinder

The food grinder mechanism is designed to process large pieces of leftover food. This mechanism performs the function of protecting the dishwasher pump from clogging the impeller area with food debris.

Residual food grinder. Damage or loss of performance of this structural element leads to blockage of the water supply lines. As a result, the dishes remain dirty after washing due to lack of flush pressure.

If large pieces of food are not crushed enough, they can clog the drain of the dishwasher. As a result, food residues are recirculated inside the dishwasher tub.

When the dishwasher does not properly clean the dishes, it is recommended to check the drain part of the pump. With a high probability, residual food will be found there - the cause of the defect. Clean the pump and check the chopping device for defects.

Inlet valve for water

The water inlet valve is one of the most problematic dishwasher parts. It is possible that it is the inlet valve that is the reason why the dishes are of high quality.

The inlet valve ensures the correct water level in the dishwasher tank. And when the amount of water is not enough, the quality of washing dishes is naturally disturbed.

Solenoid valve through which water is supplied for washing dishes. If this part does not work or works intermittently, the quality of the wash will deteriorate.

The water valve is usually located on the back of the dishwasher, behind the bottom decorative panel. When the proper water level is not reached or there is no filling at all, first of all, the water supply to the valve is checked.

It is necessary to check the connection of the valve, to make sure that power is supplied to the device during the dishwasher filling cycle. This can be done using a measuring electrical device - a multimeter. If water does not flow through the valve, but power is supplied to it, then the valve needs to be replaced.

Dishwasher and water pipe dispenser

Dirty dishes coming out of a top spray dishwasher can again be due to problems with the water supply. But in this case, the cause is the water supply pipe from the pump to the upper spray arm.

Dishwasher and pump impeller malfunctions

Dishwashers are often equipped with a pump that has two impellers. One impeller is designed to create pressure on the water atomizer, the second one works as a drainage impeller. But there are also separate options.

Traditional malfunctions of the dishwasher pump impellers are broken or damaged blades. As a rule, these parts are made of plastic and if large hard food waste (bones, grains, bones, etc.) gets in, there is always a risk of damage to them.

The plastic impeller of the pump is a potential object for breakage from large, hard residual food entering the pump. Impeller failure is accompanied by a decrease in water pressure

Breakage of one or more blades is accompanied by a loss of pump performance. Hence, a decrease in spray pressure and poor-quality washing of dishes.

To eliminate the malfunction, it is required to open the dishwasher pump housing, dismantle the damaged impeller and replace it with a new one.
