Bosch washing machine do-it-yourself repair does not drain water

In detail: a do-it-yourself Bosch washing machine does not drain water from a real master for the site my.housecope.com.

The Bosch washing machine, like all the products of this company, is an example of technical art. At the same time, even an excellent engineering technique is powerless in front of an ordinary user who forgets to follow the instructions for use. The Bosch Maxx washing machine also demonstrates the problem of the human factor, which, despite all the tricks of the manufacturer, often does not drain water after a certain period of operation. Despite its "age", this model demonstrates the best service life, but subject to the requirements for operation.

Mentioning Maxx, as well as its predecessors, it should be noted that this is one of the best models, distinguished, above all, by high reliability. But any masterly developed technical scheme in practice is incomparable with the strength of the human factor.

Engineers come up with many tricks, sensors, sabotage methods (multiple rounds of a problem situation) in order to avoid breakdown, but the situation with draining water without a person is in no way incorrigible. This applies to both new models and well-proven ones.

What recommendations does the manufacturer give in order to achieve long-term operation:

clean the contents of the pockets of things;
check the fittings for reliability of fastening (if there are no guarantees, wash in a bag);
carry out maintenance once a year.

Taken together, a washing machine - in our case a Bosch Maxx - is a device that starts a drum with laundry in a specific mode for automatic washing by pouring and draining water. The forgetfulness of users who are strictly recommended to empty their pockets before washing is known to everyone, so the protective filter is often clogged.

Moreover, it can get clogged thanks to its owner and because of the washing of specific things. For example, bedding for cats, dogs, woolen things. The popular Bosch WFF 1201 washing machine also suffers from this, which often does not drain water from pet owners. Usually, users who are faced with the use of things with increased pollution are more likely to complain.

Microfibers, which are washed out of the fabric, as a result accumulate in the filter and lead to its complete clogging. To avoid this, the manufacturer came up with an annual free (!) Maintenance, which should accustom the owner of household appliances to perform mandatory actions. Namely - to call a certified master for inspection and maintenance of the machine. Both Bosch cars and washing machines are in need of maintenance, despite their proverbial reliability. Moreover, the modern user is incorrigible.

Attention to what you need to do regularly:

clean the filter;
check the pump for performance;
ensure that the electrical circuit of the device is checked, especially in houses with old electrical wiring (the operation of the sensors, the state of the microcircuit, first of all, the state of the resistors for failure);
check the functionality of the board.

Of course, these works are carried out only at the moment of failure of the washing machine. At the same time, if the Bosch washing machine of the Maxx and WFF 1201 models is maintained in normal condition, the problem when it does not drain water due to a clogged filter or more complex breakdown can simply be avoided.

Common causes of breakdown with water drainage problem:

the debris filter is clogged (in this case, you can use the emergency drain and clean the filter yourself, see the video);
the drain hose leading to the sewer system is clogged;
the pump that diverts the water is faulty;
the water level sensor is defective (especially when transporting the machine without transport fixation).

Of the listed reasons, you can only eliminate the clogging of the filter yourself. Other faults should only be checked and rectified by a professional technician specialized in Bosch washing machines. In general, these breakdowns are standard for all household appliances of this kind, but the availability of original components or good "replicas" guarantees you long-term operation even after a breakdown. At the same time, it is still more expensive to wait for a failure, it is better to call a foreman for a preventive examination in advance.

How to identify a breakdown? If the device squeezes out, but drains poorly, the problem is most likely in the filter; the pump and water level sensor can also be seen in a malfunction. In this case, problems usually arise gradually and begin precisely with a clogged filter. This must be taken into account from the moment of purchasing the machine and use, for example, special bags for washing woolen items with a long nap, as well as clean the surface of pets from dirt.

If you have already encountered a breakdown when the device does not drain water well:

use the emergency drain located near the filter (see photo);
clean the filter yourself;
disconnect and check the sewer hose;
then start rinsing again;
call a technician for maintenance.

The foreman will inspect the machine and carry out tests of the equipment, check how it drains and squeezes out, ensuring timely and inexpensive replacement of functional elements. Otherwise, after several breakdowns, replacement of components will be approximately 70% of the cost of a new car and will be almost useless. In this case, preliminary repairs will cost up to 10% of the cost.

It is not difficult to calculate the benefits here. With the purchase of a new car and the same costs, the outdated model can be safely operated, for example, in the country. Please note that the device must be prepared for transportation by fixing the transport locks. These recommendations will help you to operate all household devices for a long time.

The washing machine belongs to the type of equipment that is constantly in demand in every home, because regular washing of linen is necessary for every family. Despite the reliable design and rare failures, the washer sometimes breaks down. One of its most popular failures is the inability of the machine to automatically drain water. Let's try to figure out why the washing machine does not drain water and what to do in this situation for the owner of the machine to eliminate this malfunction.

If the washing machine does not drain the water, then the reasons for such a breakdown can be very different. Let's list them in the order of the probability of their occurrence:

Drain hose cloggedgoing from the car into the sewer. If a siphon is also included in this chain, then it can also get clogged with debris.
Clogged filter... Coins, pebbles, paper, buttons and other items that were not put out of pockets in time can block the filter.
The drain pipe is clogged with something, which is located between the tank of the washing machine and its pump.

Example of a debris clogged pipe

If the washing machine does not drain and hums, then it is probably the pump came out of standingresponsible for pumping water. It consists of an electric motor, a shaft with a plastic impeller and two pipes. The service life of the pump is about 5 years. Often, masters disassembling the pump find threads and hair wound on the impeller shaft, which were the reasons for the failure.In addition to engine burnout, the impeller may also break, but the entire unit changes, in this case, as a whole.

Electronic control module malfunction... Its failure can occur due to power surges or due to natural wear and tear of electronic components.

Drain hose too long... Over time, the capacity of the drain pump will gradually decrease. Usually, this power is enough to drain water through a standard hose about 1.5 m long. If a longer hose is used, then the pump may physically be unable to pump water over such a distance. Typically, such a failure occurs if the old machine was moved to another place by lengthening the drain hose twice or more.

Drain hose of the automatic washing machine in a siphon

Many modern typewriters have digital displays on which not only operating modes are displayed, but also error codes that occur. For these codes, using a special table in the instructions, you can determine the nature of the malfunction for a more accurate diagnosis.

Some programs installed in washing machines may not provide for a spin mode, so the machine is waiting for an additional command, pausing during the washing process. Therefore, if the washing machine does not drain the water and does not wring it out, then you need to make sure that the required operating mode is set on the machine.

Important: If the washing machine draws water and immediately drains it, then the reasons may be a failed water level switch, an inoperative inlet valve, or a problem with the electronic module. In the latter case, you are unlikely to be able to fix the problem yourself.

If the automation refuses to drain the water, then you will have to perform this procedure yourself. Let's look at how to drain the washing machine. There are several ways to do this. Choose the one that is most convenient for you and drain all the liquid from the tank:

Unscrew the filter located on the bottom of the case, after placing a container for water under it. Tilt the machine towards the filter and fix it until the water drains out. The container should contain all the water in the tank.
If water does not flow through the filter, clean the pipe through which the liquid is drained. Sometimes it is enough to slightly wiggle the pipe so that water gushes out of it.
In case of other failures, drain the water with a hose, simply by lowering it into the tank of the washing machine, according to the law of communicating vessels.

Let's list the procedure for troubleshooting:1. Disconnect the washing machine from the mains.2. Cleaning the filter. On the front side of the machine, at the bottom, there is a hatch, under which a filter is hidden. It must be unscrewed and inspected. If it is clogged, it must be rinsed with water. If a filter is the cause of the problem, then water will flow from the pipe when you unscrew it. To prevent flooding, you need to prepare a basin for water.

Cleaning the washing machine filter

3. If the washing machine still does not drain the water, what should I do? We check the drain pipe. To disassemble it, you need to unscrew the fastening screws of the drain unit. After that, the branch pipe is removed and checked. If it clogs up in some place, you can feel the blockage with your fingers. After checking, the branch pipe is installed in its original place.

Drain connection

4. Also, one of the reasons that the washing machine does not drain water may be a jammed impeller. It is located behind the filter. Often some small objects and threads fall into it. Check if it rotates freely. To do this, scroll through it. If the impeller does not rotate, then it is jammed, and it will have to be freed from objects that interfere with it. If it does not jam, then the pump itself is likely to fail.

5. To diagnose the pump, it is necessary to unscrew the filter and set the spin program in the washing mode selection menu. Use a flashlight to light the drain hole.If the impeller of the pump is in a stationary position, then you should suspect a breakdown of the pump. The defective pump must be replaced.

6. There are times when the pump impeller rotates on dry spin, but the water is not drained. Such a malfunction is more typical for old units, the components of which are already worn out. Inside the pump, in a plastic cup, there are permanent magnets. The glass is protected from water getting on the magnets by a cuff located on the shaft. When voltage is applied to the pump winding, the permanent magnets begin to rotate, driving the stem.

If the sealing collar is damaged, then water begins to seep into the glass, and with it, dirt. As a result, the magnets cannot fully work, and pump wedging is observed in the spin mode. In addition, over time, the magnets themselves can gradually demagnetize, which also leads to a decrease in pump power. A symptom of such a problem is the noise emitted by the pump. In this case, the pump itself does not work, but only makes noise.

Tip: If your typewriter is more than 6-7 years old, and it makes noise during spinning, the likelihood of pump failure is very high. It needs to be replaced.

One of the most difficult failures, in which the washing machine stopped squeezing and draining water, and also hums, is a pump malfunction. In this case, it will most likely need to be replaced.

Washing machine pump

Consider the procedure for replacing the pump:

It is necessary to remove the drain assembly.
The drain pump is detached from the drain unit.
The wires suitable for it are removed from the pump.
A new unit is installed in place of the old pump.
Wires are connected to the new pump.
The drain assembly is installed in its place.
The machine is connected to the mains and a test wash is performed.
If the washing machine continues to drain poorly, contact the service department.

In order for the washing machine to serve reliably for many years, we advise you to adhere to some simple recommendations:Using these simple tips, you will be able to use your washing machine for its intended purpose for many years.

If the washing machine won't drain the water, it may not be a trivial problem at all. There are a lot of things to check before you can find the true cause of the malfunction, localize it, and then fix it. In this publication, we will tell you how to determine roughly where to look for the problem based on external signs of breakdown, we will tell you which parts will have to be removed and how to check them without resorting to the help of a wizard. We hope it will be interesting.

As soon as you find that your Bosch Maxx 5 washing machine or any other is giving out a water drain error, you need to restart the equipment and see at what stage this error pops up. Here you need not so much to look as to listen. If the pump is working, the drain is on, but it is carried out too slowly, an error pops up due to the fact that the system cannot remove dirty water from the tank in 10 minutes. In this case, there is a whole list of reasons:

blockage in the pipe between the pump and the tank;
blockage in the sewer;
blockage in the siphon;
a blockage in the trash filter;
the pump is clogged.

In slightly more rare cases, the machine cannot remove water in time due to a broken impeller. As a result of a factory defect or for some other reason, the wings break and the pump, although it is functioning, cannot effectively pump out water. We will check everything. Let's start with a simple trash filter.

If you don't know what a trash filter is and have never cleaned it, this is probably the cause of the problem. In the front, in the lower right corner of the body of the Bosch Maxx 4 washing machine or any other, there is a small hatch. You open the door, and behind it is a large black cork. Submit a rag, or better, substitute a small basin and unscrew the cork.

Be careful! When opening the dust filter plug, be prepared for dirty water to pour out.

Inspect the inside of the debris filter and the plug itself. Remove dirt, hairballs, hairpins, coins, etc. from there. Wipe the inside with a cloth and screw the plug into place until the end. If the problem is not resolved, you need to climb further. Check how quickly the dirty water goes down the drain. Turn the tap on full and see. If the water does not drain well, there may be a blockage in the siphon or sewer. By clearing out the blockage, you will solve the problem with the typewriter.

If the drain does not work, the cause may be a clogged drain hose that goes from the body of the washing machine to the siphon connection. It is necessary to carefully remove the hose from the fitting and check it for blockages. The clogged hose is cleaned with a wire or pierced with a pressure of hot water.

At the next stage, we start looking for a breakdown already in the bowels of the washing machine. From the front, you need to unscrew and remove the narrow front panel, which is located just under the front of the washing machine case. We check the pipes, the pump, we find a blockage or a foreign object and remove it. After that, of course, we assemble the car. If partial disassembly of the Bosch washing machine causes you difficulties, read the article of the same name, previously posted on our website, and we move on.

A breakdown of the drain pump demonstrates similar symptoms. It can hum, but not drain the water or not hum at all, then it turns out to be quite simple to localize the problem. We get to the pump and check its coil with a multimeter. If the unit does not ring, you can safely change it to a new one. If it rings, but does not work normally, you can disassemble it and see the causes of the malfunction, but it is better not to bother and replace it.

Buy only original spare parts. It is better to overpay a little for a Bosch branded pump than to repeat the repair after a few months, risking buying Chinese spare parts. Maybe they will last for a while, but most likely, you will throw your money down the drain.

It so happens that the Bosch machine does not squeeze out or drain dirty water, although there seems to be no blockage, and the pump is functioning normally. What, then, is the "buried dog"? Often, Russian-assembled Bosch washing machines have errors in the firmware of the electronic module. Such errors can manifest themselves in different ways, for example, blocking the operation of the drain pump.

We would categorically not recommend you to reflash the control module with your own hands. This will only make the problem worse.

What to do in such a situation? Of course, you need to entrust this matter to a professional. The wizard will test the electronics, reset the firmware and restore the system to work. Typically, an event takes 20 to 40 minutes. In severe cases, the firmware will need to be updated, but don't worry, it won't take much longer. Replacing the control module in such a situation is not required, so you will get by with "little blood".

So, in most cases, the problem with a bad drain is solved on its own. You just need to look very carefully at how the washing machine will behave, localize the malfunction, and then fix it. Especially you don't have to disassemble anything. All problematic elements can be reached relatively easily. Difficulty may arise with the firmware, but it is very difficult to solve this problem on your own. Better to contact the master!

You can check the drain hose by first disconnecting the machine from the mains by blowing strongly into it.
If everything is in order with the hose (blown through), check if the machine is disconnected from the mains. Then, slowly unscrewing the filter cover, in small portions, drain all the water from the washer (this is long, but necessary). After draining the water, check the pump (drain pump) and the filter itself for foreign objects. At the same time, check the water supply from the tank of the machine for clogging.

If you checked everything, but found nothing strange, then the possible reasons are:
Pump malfunction - replacement is recommended;
Control module malfunction - repair or replacement is possible;
Electrical malfunction - replacement.If the reason is not clear, we recommend calling the wizard! Image - Do-it-yourself Bosch washing machine does not drain water

Have you decided to wash your laundry and noticed that the washing machine does not drain the water? Unfortunately, this is one of the most common problems. The reasons for its occurrence can be different.

But before talking about the reasons, let's look at how this problem manifests itself. And what kinds of it are:

Water draining is extremely slow, while the program may malfunction.
During the course of the program, the process stalls at the moment when the water should be drained. The water does not drain.
For some washes, the water drains out, for others it does not.
Everything is fine during the main wash, but no draining occurs during rinsing.
The spin mode is blocked after draining.

What could be the reasons for this malfunction? Let's list them:

The connecting pipe (between the tank and the pump) is clogged with debris.
There was an extraneous thing in the pump.
The pump filter is clogged with debris.
The pump has broken.
Sewer or siphon blockage.
Clogged hose through which water is drained.

Before repairing the washing machine, you must de-energize it. Do not neglect safety rules. And so, first we disconnect the machine from the electricity by pulling out the plug from the mains.

After that, let's check our filter. It is located at the bottom of the case from the front. During work, some water may spill onto the floor. Therefore, it is best to prepare a rag or small empty container in advance. If you see that the filter is clogged, then simply clean it of any foreign matter. This procedure can solve the problem you are experiencing.

For clarity, we will demonstrate the entire process of removing the filter of the washing machine in the video:

But what if the filter is removed and the problem persists? That is, the washing machine is not draining the water? In this case, we proceed to the next stage of the repair. Namely, to cleaning the branch pipe connecting the tank of the washing machine and the pump (pump).In order to gain access to it, it is necessary to unscrew the bolts that fix the fasteners of the drain unit. After that, we take out the branch pipe, remove the fixing clamp. Then we drain the water from the pipe into a pre-prepared container.After that, you need to check if our branch pipe is clogged with any debris. To do this, squeeze it slightly in different places. If you feel a blockage, it must be removed. After that, we collect the entire structure in its original state. Image - Do-it-yourself Bosch washing machine does not drain water

If this did not solve our problem, then move on to the next possible malfunction. Now we will check if the pump impeller has jammed. It is located directly behind the filter. If even a small thing gets into it, it can cause a malfunction. So try turning the impeller first. If it rotates and you cannot see any extraneous things, then everything is in order with it. And if you find something superfluous, for example, a coin or a button, remove it.If this did not help, then it remains to check the drain pump (pump).

In order to check the serviceability of the drain pump, we will remove the filter, as you have already done this before. After that, we will install the program for spinning. And highlight the filter hole. The easiest way to do this is to use a regular flashlight. If the pump impeller does not move, then the pump (drain pump) is broken. After all, we have already checked it for foreign objects. And this is the only explanation that the impeller does not rotate. And since we have established the malfunction, then we proceed to the next stage - replacing the broken part.

But before that, we need to purchase this very part. Most washing machines are assembled using standard parts. Therefore, we can easily find the new pump we need without any problems. If you do not know where you can buy it, then the easiest way is to use the Internet to find a seller. Namely, search engines Yandex, Google,> or others. Type in the search line: "buy a pump for a washing machine in Moscow", "in Moscow" you need to change to your city, if you are not a Muscovite. Then find sellers in the search results, call them and buy a new pump.

And so, we have already bought the pump. Now let's remove the broken one and replace it with a working one. To do this, we need to remove the washing machine drain unit. And detach the drain pump from this unit. Then he carefully removes the wires from it. Then we take out a working drain pump and install it in place of the old one. We attach wires to it and so on. And we collect the machine in its original state.

To facilitate the whole process, we have selected a video that shows the entire process of removing and replacing the drain pump. See:

When assembling, be careful with the attachment points. Check that the clamps are in place and that they are tight, tighten all the screws and make sure that all parts are in place.After that, we will check the performance of the machine by performing a test wash. Be careful when washing. If a leak occurs somewhere, it means that some connection was not properly secured. In this case, correct this defect and check the operation of the washing machine again.We hope this article helped you solve the problem. Have a good day!It is quite possible to do it yourself repair the drain pump of your washing machine without calling the master. But first, you need to carry out the simplest diagnostics of the device.If the machine does not work properly, before disassembling the drain system, you need to make sure that the malfunction is located exactly in this place. It can be determined by several criteria:

the water drain program has started, but the pumping system does not work;

during the drain, strong noises and buzz are heard;

water is pumped out, but flows out very slowly;

during the operation of the system, the machine may turn off;

the pump motor hums but no water flows out.

If one of these breakdowns is found, it can be said with a high degree of probability that the washing machine pump will have to be repaired.There are different ways to remove the pumping system from the body of an automatic washing machine (CMA), depending on the model of the unit. In models Whirpool, Samsung, Ariston, Beko, LG, and others, no bottom... Accordingly, you can remove the pump by tilting or laying the device on its side, and disconnecting the bottom panel (open the door or hatch). After that, you will see the screws that secure the snail with the filter to the front plate.Everything is very simple in Electrolux and Zanussi CMAs. It is enough to open back cover machines, and you will see the desired unit, which must be disassembled. The most difficult access to the required part in the AEG AEG, Bosch and Siemens. You can get to the pump only by removing front wall washing machines.But before removing and repairing the drain pump in the washing machine, you must first check the reasons due to which the water may not be pumped out:

severe blockage drain hose (it is necessary to remove it and clean it well);

drain filter clogged with debris (remove the filter from the snail and rinse well with water).

If the check and cleaning did not give results, after a test run of the rinse and drain mode, you need to remove the part and try to repair it.To disassemble your pump for troubleshooting, first disconnect it from the snails... To do this, you need to unscrew the screws.Some pump models have a different attachment to the volute. It is enough to turn it counterclockwise and it will detach.In the next step of troubleshooting, check impeller. Although it can be seen without disassembling the entire structure: just pull out the drain filter. It is possible to visually determine whether it is broken or not. But to find out whether it scrolls on the shaft or is fixed will not work without complete disassembly.The picture below shows a broken impeller due to a coin falling into the system.The impeller should not turn easily. Normally, it turns with some delays (jumps), due to the magnet rotating in the coil.If rotation is difficult, and no visible interference in the form of various debris is observed, then you will have to disassemble the pump completely.To do this, using a screwdriver, pry the latch on the motor housing on both sides, and remove it from the coil.There are also so-called “non-separable” motors, but they are also amenable to “treatment”.After detaching the body with blades from the coil, we will see a monolithic part. It seems that the crosspiece cannot be removed. But there is a little trick.

Take the usual construction hair dryer, set it to the lowest temperature, put on gloves, and begin to warm up the shank of the part (its long part). Do this carefully.

After a while, when the shank warms up well, pry crosspiece screwdriver and carefully remove it (together with the magnet) from the housing.

There may be a lot of dirt on the magnet and in the place from which it was removed. Everything must be thoroughly cleaned, after which you can remove the magnet itself from the shaft. You will see bearing, requiring, respectively, cleaning and lubrication. Also lubricate the bearing on the bottom of the housing.Then insert everything into place, with slight pressure until it clicks. Sealing ringunder the blades should fit snugly into place.The picture below shows a dirty motor from an Indesit typewriter.In motors of this type, in addition to the above procedures, it may be necessary to replace the oil seals.Contamination is not the only reason for the device to malfunction. If the bearings fail, beating occurs during the rotation of the shaft. Due to the beating, the impeller begins to rub against the casing of the snail. This causes noise and unproductive operation of the pump, even to a complete stop.This problem is solved by replacing ball bearings, which can be purchased at specialized retail outlets or at a service center for servicing household appliances.If at the moment it is not possible to buy a new part, and the wash cannot wait, then you can temporarily extend the life of the pump by shortening blades 2 millimeters with a sharp knife. But don't overdo it: if you cut more, system performance will drop.After cleaning, replacing bearings or oil seals, the repair of the motor can be considered complete. Install the housing with blades into the spool and secure with latches. Subject to safety rules, connect a voltage of 220 V to two contacts, and check the work devices. After making sure of the normal operation of the device, you can connect the volute and return the entire structure to the SMA housing.As you can see, repairing a washing machine pump with your own hands is not such an impossible task and everyone who has carefully read these recommendations can do it.

One of the most common types of breakdowns in automatic washing machines is the lack of water drainage. The cause of the malfunction can be both a banal clogging of the filter and a complex hardware failure of the electronic control unit. Few home appliance owners know what to do if the washing machine is out of order. It should be understood that most breakdowns can be fixed on their own without resorting to expensive repairs. As part of today's article, together with Seti.guru, we will talk about what to do if the washing machine does not drain the water, what are the signs to identify device malfunctions, and consider how to restore the unit's performance.

Before you understand what to do if the washer does not drain the water, you need to figure out the causes of malfunctions of the units. The washing process can be conditionally divided into several stages, and until one of them is completed, the program will not start the next one. For example, the rinsing mode is completed, however, the washing machine does not drain the water and hums (the next mode does not turn on - spinning), the laundry floats in it, and the unit stops working. The main reason for this problem is the clogging of the drainage system.

Most often this happens due to the fact that the sewer pipe is clogged or the drain hose of the washing equipment is clogged. Similar malfunctions, due to which the water does not drain, are all sorts of objects getting inside the concentrator, nozzles and the pump device. Common reasons for the failure of the washing machine also include:

the presence of air inside the pump;
mechanical failure of the concentrator;
damage to the pressure switch device;
breakdown of insulation (breakage) of electrical wiring;
failure of the electronic control module.

Common causes of a washing machine breakdown include damage to the pressure sensor and the installation of an incorrect operating mode in which the unit operates.

Owners of equipment should pay attention to the nature of the washing machine, which will quickly detect malfunctions and malfunctions. If the vending machine stops draining water or it happens slower than usual, then it is necessary to diagnose the device for further troubleshooting. You should also pay attention to those cases when the draining in the machine began to be carried out after one or two washings, the spin mode does not turn on, rinsing does not start after draining, as well as the equipment hangs up (washing takes place in normal mode, as soon as the drain should turn on, the unit refuses execute the set program).

Complex hardware breakdowns of the washing machine include the failure of the electronic control unit. It is a board, thanks to which full control over the operation of all modes of the unit is carried out. If the electronics are out of order, the repair should be entrusted to an experienced master, since independent attempts to check the operation of the ECU and troubleshoot can lead to the fact that the machine will stop functioning altogether.

Among the reasons why the automatic machine does not drain the water, it is necessary to highlight the breakdown of the pressure switch. This device allows the unit to detect the presence of water and the fill level of the tank. If the sensor breaks down, the ECU does not receive a corresponding signal and does not turn on the pump device. A similar situation also occurs due to clogging of the expansion chamber and the narrowing of the clearance of the drain hoses. To eliminate the malfunction, it is necessary to clean the pipes, as well as replace the pressure switch.Please note that the water sensors are not repairable as they are adjusted by the manufacturer.

Quite often, the washing machine does not drain the water due to the formation of blockages in the filter of the pump device. Its location depends on the design features of the unit - it is located either at the bottom of the rear wall, or at the bottom of the front panel.

Before cleaning the filter, you must drain the water from the washer, as if this is not done, liquid will spill out under pressure and damage the floor covering. For these purposes, you need to install a capacious reservoir under the washer, tilt it, let the liquid drain and unscrew the filter for cleaning.

It should be rinsed in running water, and then installed in its seat (do the work in reverse order). It is also worth checking the operation of the drainage system, for which you need to disconnect the drain hose from the siphon, and place the free end over a capacious tank (toilet, bathroom), turning on the drain mode. If the water drains well, then the siphon is clogged, which must be dismantled, cleaned of debris, rinsed and reinstalled. After assembling all components, it is recommended to check the operation of the washing machine in idle mode.

In some cases, the washing machine does not wring out and does not drain the water, since the impeller is jammed, which is located in the pump device. In almost all models, it is installed immediately behind the filter, so it is easy to find it and see the cause of the malfunction.

Pump impeller after cleaning

Usually, the mechanism is jammed due to the fact that small objects (coins, buttons, tufts of hair, threads) get inside it. The impeller should be twisted - if it rotates normally, then the mechanism is working properly, if not, the blockage should be removed. Now let's look at why the automatic machine does not drain the water if all blockages and visible mechanical damage are eliminated or absent. The reason for the malfunction of the unit may lie in a violation of the integrity of the electrical wiring.

It occurs due to the fact that the unit is operating under heavy load, and some elements overheat. To identify the damaged section of the circuit, you need to use a multimeter (tester). The dialing of loops and wires is performed in the area between the ECU and the pump itself. Damaged wiring should be replaced with a new one or use electrical tape to fix the malfunction.

If the unit breaks down constantly, the washing machine drains water intermittently, which are accompanied by a strong hum, the cause of the malfunction may be a pump breakdown. It is characterized by such signs as the lack of rotation of the impeller due to clogging and failure of the electric motor.

The process of dismantling the pump of the washing machine

In the first case, the mechanism should be dismantled, disassembled and cleaned of accumulated dirt. To determine the malfunction of the unit, it is necessary to check the signal flow to the engine. Please note that the pump (pump unit) cannot be repaired, and the only way to fix the breakdown is to replace the entire unit.

In this section, we will analyze what to do if the machine does not drain the water due to a jammed hatch door or a broken drum bearing. The table below provides remedies for these problems.
