Dishwasher the device resembles a washing machine. The difference is small: water is used several times, sprayed with a rocker, filtered, and again supplied to the recirculation engine from the sump. Regular readers are not surprised that a pressure switch and a drain pump are installed in the dishwasher. Since the inside is dirty, there are more problems than washing. Why is there water in the dishwasher? That is the question!

How the dishwasher works

Copying the washing process, in dishwasher water enters bypassing the inlet valve. The unit is single. Water fills the tank, touching the level of the lower waterproofing of the door, sometimes heats up, is pumped by a recirculation pump through a pipe into the rocker arms. A rain of jets washes the dishes, the individual holes are directed to create a torque for the beam. There is movement.

Water is collected bottom compartment, passes through a cascade of a coarse and fine filter, is collected by a sump, according to the program it is fed again. Upon completion, the drain pump dumps the dirty stream down the drain.

The cycle progress is monitored by the pressure switch, the heating element, if necessary, heats the water, solenoid valve adds softening salt according to the readings of the sensor set to the regulator. Powder, other means are poured into the door dispenser, as needed, thrown into working chamber.

We add that the pressure of the pressure switch is taken in two places:

1. On the side storage tank during the recruitment period (preheating).
2. The level in the sump is controlled during the descent.

Understandably, the central board is free to use the information in a variety of ways.

The dishwasher does not drain the water: reasons

Clogged filters are considered the first common cause. It seems to an inexperienced viewer: the gaps are large. In practice, a rough step is followed by a thin one, it is almost impossible for a person without a magnifier to see the size of the holes. Is that the light. It will be more difficult for the owners of Whirlpool, there are those in Russia. To remove the filter, you will have to disassemble the impeller subsystem, first removing the lower one, undocking the plastic segment of the water supply. After that, you can at least remove the sump cover with filters.

Clean filter, rinse running water, try pumping out. You can manually fill the working chamber with a couple of glasses. After turning on the dishwasher, detecting the presence of water, it will try to get rid of it by turning on the pump. The convenience of the equipment, in contrast to the washing one, is obvious: the drainage pump is relatively easy to dismantle. It is recommended to remove the lower bezel. The pump can be accessed from the bottom side. Perform the required operations.

Drainage pump held by a pair of screws, in the case of the Whirlpool it will be a Torx. The mechanism resembles what was seen in a washing machine:

• The induction motor is equipped with a pair of coils at the base.
• The rotor is magnetic with several poles.
• The impeller in a cross, due to centrifugal acceleration, pushes the water to the periphery by the volute.
• Power supply 230 volts.

Bottom impeller

Check if the pump impeller is spinning. Rotates tightly, immediately by a quarter (half) of a revolution, in jerks (synchronous motor). The coils are ringing, the nominal value is about 200 ohms. It is easy to check the mechanism by connecting it to the 230 volt mains. We remind you again: the startup mode is individual, it is indicated in more detail by the unit body. When dismantling the pump, water will probably pour down. There are no emergency measures in dishwashers, the volume is small, inferior to washing ones (devoid of Aquastop).

In most cases, the pump reels will be wound by hand. The cost of a new part starts at 300 rubles. Is it worth wasting time, decide for yourself. The rotor can be adapted for self-made structures in the future.

Dishwasher pressure switch

There is still water in the dishwasher - the pressure switch is to blame. Both pressure chambers are made to prevent water and food pieces from getting inside. Only air. The sump pressure take-off chamber is held on one or two screws and is removable. You will see a small plastic box set upside down. From under the bottom, notice: a transparent pressure switch tube fits to the pressure chamber. Using pliers, remove the clamp, dismantle the plastic part.

It happens that food is clogged inside, the pressure switch readings are incorrect, the water is not pumped out, even if the liquid has filled the sump. The tube is sterile clean. Disconnect from the side of the pressure switch, blow out. Then you should reliably check the performance of the pressure (level) sensor. From the side of the pressure switch, the tube clings back. Blow to hear a click.

Please note: the sump water is constantly moving, the level is changing. From here there is a fence re circulation pump... To avoid constant clicks of the pressure switch, the path is made with a time delay. As a result, the number of triggers is reduced.

The click will be heard with a delay of 1 - 2 seconds. Blow, wait. A sound is heard - all the way. The second channel, from the side of the intake tank, works without delay (avoiding getting too much). We suspect that for this reason it was necessary to embed two sensors when logic dictates: you can get by with one. Check the second one: who knows the logic behind the operation of a dishwasher of an available brand. After checking the mechanical part, the time to investigate the electrical has come.

With the tester in hand, the tubes in the mouth, the contacts start ringing. If a response is detected in the form of a decrease in resistance to zero, we consider the performance to be complete. There are other reasons why water remains in the dishwasher. There is a blockage in the drain hose. Check the drain by detaching from the pump.

The dishwasher is constantly trying to drain the collected water.

First, the problem lies in the leakage microswitch pressed down by the float valve. The mechanism is hidden by a pallet, easy to test. Ring the winding at the lower, upper position of the float. The result is different (open-circuit). If there is indeed water in the pan, try to figure out the path for the liquid to enter. Repair the leak. Drain the liquid, drain the drip tray, try restarting the dishwasher.

The second reason is more trivial. The water outlet of the drain hose is located below the filling level of the tank - spontaneous descent will occur. Installation instructions indicate basic dimensions, check repeatedly.

In dishwashers Bosch machines the amount of water collected is measured by a flow sensor. The sensor is located behind the inlet valve, shows the dialed amount. The flow sensor is defective - the dishwasher will continuously drain water. Electronics is powerless to understand what is happening. One amount of water is collected, more is recorded. The pump drains part - the level sensor signals: there is not enough liquid for the cycle. If there is a constant drainage situation, check the flow meter next to the inlet valve.

We have listed the main types of malfunctions associated with the intake and drainage of water. Check the pump performance without dismantling. The impeller is visible from the filter compartment. When plugged in, the dishwasher starts draining water. Several attempts are made, 2 - 5. By the rotation of the blades, evaluate the completeness of serviceability. In parallel, it will not interfere with the tester to measure the presence of voltage. Check the technical details yourself, access from the bottom.

Both pumps exploit the action of centrifugal force, such pressure is created that the jet of the rocker arm flies out, gaining a speed of 150 km / h. The drain pump is just draining water through a hose into the sewer. Most dishwashers are equipped with error codes. The manual lists the meaning of the alphanumeric sequence. Otherwise, you can search the Internet for these purposes.

In rare cases, the main engine fails. The cycle seems to continue according to the readings of the sensors, the rocker arm water does not splash. We believe the error codes will be more eloquent. Look through the manual carefully. Look, take the trouble to find information on the self-control mode. As a rule, a debug run helps to find out the performance of parts.

This was the beginning, then why write a review about why the dishwasher does not drain the water! We hope the story is informative, we thank the network enthusiasts who translate foreign videos into Russian, foreign service and distribution centers - for creating an instructive movie about dishwashers. Let us remind you that everywhere we try to show household appliances from the inside, so that readers do not just pick the appliances, but understand the meaning of the action.

When Appliances works properly, we take it for granted. A breakdown always becomes an unpleasant surprise, for example, when the dishwasher does not drain the water. In fact, there is nothing wrong with that. Most faults can be rectified by yourself if you know how the dishwasher works and works.

How does a dishwasher work

After the first use, the liquid passes through coarse and fine filters, and then takes further part in the process of washing and rinsing the dishes. In the normal mode, this cycle is repeated two times, due to which water is significantly saved. When the work is finished, the dirty liquid is removed through the drain system.

Reasons why water does not drain

When nothing portends problems, but the dishwasher does not drain the water, then the cause of the trouble may be a breakdown of one of the parts of the drain system or a blockage that prevents the liquid from entering the drain.

The problem may be one of the following:

1. The drain filters are full of food debris and other debris.
2. The sewage system is clogged, into which the dirty water is drained.
3. The drain hose is pinched or clogged.
4. There is a blockage in the drain pump (pump) or it is faulty.
5. The water level sensor (pressure switch) has stopped giving correct information.
6. The software control module is out of order.

As you can see, there can be many reasons why water does not leave a Bosch dishwasher or other brand equipment. In order to fix the problem, you need to start by identifying blockages in the system.

Clearing blockages

Most often, the Bosch dishwasher does not drain the water due to debris and food debris trapped in the drain. Before sending dishes to the PMM, always clean them of food debris... This will keep the drain filters from picking up debris too quickly. If you use the dishwasher daily, the filters should be cleaned at least once a week.

When inspecting the filters, make sure that debris and food particles do not enter the pump. In order to check this, you need to do the following:

• free the camera from all baskets;
• in the bottom, unscrew the filter cover and remove it;
• wash the filter element using a soft brush and detergent;
• unscrew the pump cover, which should be in the same place under the filter;
• Examine the space under the cover and impeller carefully, and remove debris if you find it.

About what's in the dishwasherBosch filter is clogged or the pump impeller does not rotate well, indicated by error codesE22 orF22, highlighted on the display.

Sewerage problem

Oftentimes, the dishwasher will not empty the water due to a blockage in the sewer system... If no debris is found in the PMM, but in the drain mode all the liquid does not have time to leave the chamber, follow these steps:

1. Disconnect the drain hose from the drain. If water has flowed out of it, there is probably debris in the pipe.
2. If the blockage is minor, pour boiling water into the sewer hole.
3. For more effective cleaning mix table salt and baking soda in equal proportions. Load the mixture into the sewer hole and fill it there too. hot water... After 20-30 minutes, flush the system with running water. You can use the "Mole" tool and another household chemicals designed for these purposes.
4. If all attempts are ineffective, call a foreman who will unclog the drain with a flexible steel cable.

Clogged drain hose

This problem is quite rare, but it is also quite possible. This malfunction is indicated by error codes E24, E25 or F24, F25 on the Bosch PMM display. First, make sure the hose is correctly positioned and not pinched or kinked.

Without removing the hose, you can give it a "massage" by stretching your hands along its entire length. Then you should check whether water flows from it when draining, having previously disconnected it from the sewer and placed it in an empty bucket.

If such actions did not help, disconnect the hose from the PMM. Then direct a stream of water into it with a strong pressure - it should knock out the debris. In case of failure, it remains to purchase a new hose in the same store where the dishwasher was purchased.

Identification of faulty parts, their repair and replacement

If there is no blockage, but the dishwasher does not drain the water, you will have to look for the faulty part. First of all, pay attention to the pump.

Checking and replacing the pump

During draining, the pump emits a characteristic sound that comes from the lower part of the PMM housing. If on the final stage there is silence, but the drain does not start, this means that the pump is not working.

If such a breakdown is detected, take a number of actions:

1. Remove water from the PMM chamber with any in a convenient way- with a sponge or by tilting the machine forward.
2. Remove the filter element from the seat.
3. Place the device on the back panel and, after unscrewing the screws, remove the pallet. Be careful - there may be a leakage protection sensor on the pallet. If there is one, disconnect it from the cable.
4. Remove the pump - disconnect the cable connectors from it, loosen and remove the clamp, then disconnect the part from the distribution mechanism, from the salt ion exchanger and the movable support (see video below).
5. Measure the resistance of the pump winding with a multimeter. Its value should be within 200 ohms. Check the integrity of the cables coming from the control box and make sure that the pump is receiving voltage. If there is voltage, but there is an open or short circuit in the winding, change the pump.
6. Check how the impeller turns. If this does not feel intermittent, the pump is faulty and will have to be replaced.
7. Assemble in reverse order.

Problems in the operation of the pressure switch and control board

These details can also be the reason that the dishwasher does not drain the water. The control block is the brain of the PMM. If there is a memory failure, contact failure or failure of one of the unit's parts, the unit's operation is disrupted.

When the pressostat sends erroneous information about the water level to the control unit, the PMM cannot drain it (since there is no water, there is nothing to drain). Since the diagnosis of parts and their repair require a certain level of skill, in case of such breakdowns, it is better to contact a service center.

As you can see, most water drainage problems only seem serious. Owners can eliminate them on their own with the simplest skills. We hope that our article will help you quickly restore the equipment to work.

What to do if the drain or pump does not work in the dishwasher Bosch (Bosch), Electrolux (Electrolux), Beko, Samsung, Whirlpool, the dishwasher does not completely drain the water or does not always drain? Later in this article we will talk about possible reasons and ways to solve the problem. Possible Symptoms problems with draining:

• water drain does not work at all;
• the drain is slow, the washing program is not running correctly;
• water is not drained only in certain washing modes;
• water remains in the chamber after draining;
• the machine collects water and immediately drains it;
• spontaneous drainage of water;
• the dishwasher hums and does not drain.

If your dishwasher does not drain the water, you urgently need to figure out the causes of the problem: it can be either a clogged drain filter or a breakdown of one of the machine components, for example, a drain pump, sensors or a control board.

You can easily eliminate the most common causes yourself, without wasting time and money on calling the master: clean the drain filter, check the drain hose, make sure that the drain is properly connected to the sewer. But if there is a breakdown of some internal unit of the machine or you cannot independently determine the cause of the malfunction, it is better to stop the experiments and call a qualified specialist with necessary equipment and skills.

Our clients often ask the following questions:

• The dishwasher does not drain the water: reasons for what to do
• Dishwasher Bosch machine does not drain water

The drain filter is clogged with debris.

Symptoms: the water either does not drain at all, or the drain is slow, or water remains in the chamber.

A clogged drain filter is the most common reason poorly working drain. Fortunately, cleaning it is not a problem.

Usually the drain filter is located at the bottom of the chamber. Carefully free access to the filter (you need to pull out the lower basket and, possibly, remove the lower spray), unscrew the filter glass, take out the mesh and rinse it and the filter. Just in case, check to see if there is any debris left under the filter.

If the filter is clogged, clean it, replace it and restart the washing program. If this does not help or the filter is clean, then the cause of the problems with the drain is in something else.

Kinked, damaged or clogged drain hose

Symptoms: Water draining too slow.

Problems with the water drain hose lead to the fact that the sink will take "forever" due to slow drainage.

First, swipe visual inspection hose: it should not be pinched anywhere, nothing should lie on it and it should not have visible damage. If puddles are visible next to the hose, this is a reason to check in those places for cracks in the hose.

If the hose is visually in order, it is better to disconnect it, just in case, and rinse it under a strong pressure of water, it is better together with special detergents... To finally make sure that everything is in order with the hose, disconnect it from both the machine and the water supply system, fill it with water, and see if there are any leaks somewhere.

Clogged plumbing

Symptoms: It takes too long to drain the water.

It is possible that your dishwasher is in perfect order, and the entire drainage system in your apartment is not working well. First you can check that the draining of the machine is working properly. Disconnect the drain hose from the sewer, put it in some decent-sized container and start a program that drains the water: if the water flows from the drain hose fast enough, then the sewer is to blame. If the drain hose is connected through a special siphon, it may well become clogged. To be sure of this, check how you drain the water from the bathroom or sink.

Drain pump clogged

Symptoms: water remains in the tank after draining, the pump makes strange sounds.

The main element of the drain system is the drain pump (pump), and one of the most vulnerable parts of the pump is its impeller. If foreign objects get there, they can not only impede the rotation of the impeller, but also break it.

Simple check and the impeller can be cleaned by yourself. If the design of the dishwasher makes it relatively easy to get to the drain pump, you can check and clean it yourself. Usually the drain pump is located somewhere at the bottom of the machine next to the drain filter: once you reach it, try to turn the impeller with your fingers. If it spins freely, then the problem is something else, but if there are obvious traces of debris, the impeller is jammed or it rotates with difficulty, try to clean it without removing the pump. Shine a flashlight, try to find foreign object to the touch and remove it. If, after your efforts, the impeller begins to rotate freely, turn on the drain program and see if the drain works. If it doesn't help, it's a bad thing: either the reason for the bad drain is different, or the breakdown of the drain pump is more serious and here you cannot do without calling the master.

We are often
ask

The dishwasher does not drain the water, what to do

The Electrolux dishwasher does not drain

Dishwasher Bosch does not drain water

Breakdown of the drain pump

Symptoms: the drain does not work and the impeller of the drain pump does not turn.

The impeller of the drain pump may not spin because of it, but if you cleaned the impeller, and the blades still do not spin, then the drain pump itself does not work in the dishwasher.

In principle, the drain pump is a standard part, and it is quite possible to find it on sale, but replacing the pump will require a complete disassembly of the machine, which, you must admit, not everyone can do. It's better not to risk it and turn to professionals.

Water level sensor does not work

Symptoms: water from the tank does not drain or is drained without interruption, water remains in the tank.

Defective water supply sensor sends to electronic system the machine gives incorrect information, because of which it issues incorrect commands - the consequences can be any: the dishwasher does not start draining the water at all or leaves water in the tank, or it may even drain the water constantly, since due to a sensor breakdown, water will be continue to fill the tank.

The sensor cannot be repaired, it must be replaced, and this is a job for a professional technician.

Control board failure

Symptoms: Any problems with draining the water

It is, of course, only a qualified specialist who can determine exactly that the faulty control unit is to blame. And you definitely shouldn't get into it for an unprepared person: the consequences will be fatal, including possible breakdowns other expensive dishwasher components. Usually the control module is changed or reflashed.

Incorrectly connected drain to sewerage

Symptoms: The dishwasher constantly draws in water and drains it out immediately.

If you notice that during the filling of water into the tank of the machine, it is simultaneously drained from there, then with a high degree of probability, when installing the machine, the drain was connected to the sewer incorrectly.

To prevent spontaneous draining, the drain hose must either be connected through a special siphon, or be attached to the sewer at a height of 50-60 cm from the floor. If the hose connection is not available, there is a simple way to make sure that the cause of the drain is in the wrong installation: during the drain, press pause and check if the water continues to drain - if "yes", then you have found the cause. But how to eliminate it is up to you: if you have necessary tool and skills, you can easily fix the drain yourself, but it's better to call a specialist after all.

Prevention of malfunctions

In order for your faithful assistant to serve for a long time, and there is no reason to contact a repair shop, you just need to follow simple operating rules:

• follow the installation rules, do not try, for example, to lengthen the drain hose;
• soften water with special means;
• clean off copious food residues from the dishes before placing them in the machine;
• dry the chamber after washing;
• descale the dishwasher regularly;
• as often as possible, preferably once a month, check and clean the drain filter from debris;

The dishwasher has been operating as usual for many months, but suddenly stops in the middle or at the end of the cycle and refuses to drain. Do not rush to despair and overlook new technique... The reason may be a simple problem that you can fix yourself. In the article we will consider why the Bosch dishwasher does not drain the water and what to do about it.

Why doesn't the water go down the drain? There are several options for the development of events. The simplest is a blockage or pinching of the drain hose. Check if it is level - it may be bent or caught by some object.

The sewage system at the junction with the drain hose could be clogged.

Other reasons for stagnant water in PMM Bosch:

In the event of such malfunctions, the display of the machine may show fault code E24, E25 or "END".

Let's figure out what to do if water remains in the dishwasher.

DIY Bosch PMM repair

Begin checking with the drain hose and drain. Disconnect the hose, take a deep container and lower it into it. Start drain mode. If the water is freely poured out, then the cause is a blockage in the sewer. You can clean it with special powders or call a plumber.

How do I drain the water from the hopper? Use the drain hose as described above, or place a container and drain off the rest by tilting the dishwasher. Automatic draining is carried out in each model in different ways, the steps are described in the instructions. Here are some options:

• turn the ratchet switch and the drain valve will open;
• in PMM series SRV, SGV, you need to reset the programs and close the chamber door more tightly;
• for SMV, SPV models, the "Start" key is pressed for three seconds.

Then open the hopper door and unscrew the drain filter in the pan. Rinse it under pressure from the tap, additionally clean the mesh with a brush.

If the problem was not immediately noticed, the drain pump worked for a long time, trying to pump out the water. As a result, the part could burn out.

How to check and replace your pump:

Now inspect the pump for blockage. Diagnostics of the electronic part is carried out with a multimeter. If you notice a problem, then it is better to install a new part.

Is the pump working as expected? Inspect the pressure switch - in Bosch dishwashers, it is also attached to the engine. The part looks like a plastic box with a tube and a pressure reservoir. How to replace a pressure switch in a dishwasher, read the article.

The most unpleasant failure is the failure of the control module. A breakdown can happen for various reasons: sudden jump voltage, moisture, short circuit. Not the entire unit can fail, but its individual elements. Then the board can be repaired, but only a specialist should do this.
