Why doesn’t my Bosch washing machine drain water? How can I fix the problem?


Owners of washing machines from time to time encounter technical malfunctions of their assistants.

Bosch devices, despite all their reliability, can also fail. One possible problem is the lack of water drainage.

In some cases, it is even possible to cope with a failure on your own. We will explain further why the Bosch washing machine does not drain water.

Reasons why the drain does not work

There may be several reasons why the washing machine did not drain the water. Among them are user errors, blockages and technical breakdowns. This situation may occur after the end of the washing phase or after rinsing.


Reasons why draining does not occur:

  • selecting a washing mode without draining;
  • kinked/clogged drain hose;
  • sewer blockage;
  • clogged drain filter;
  • pipe blockage;
  • problem with the pump;
  • control module failure;
  • breakdown of the pressure switch.

To analyze the condition of some components, partial disassembly of the washing machine will be necessary.

Diagnostics of a Bosch washing machine

Some factors can be checked without the help of a wizard . If there is no code on the display, you can simply inspect the Bosch washing machine itself, check the condition of the sewage system in the apartment and clean the filter. If error F03 is displayed, this indicates that the device has problems with drainage.

When is water in the tank normal?

Quite often, water remains in the tank due to the fact that a washing program without spinning and draining was accidentally or deliberately set. In this case, water will remain in the tank, and this is a normal situation, taking into account the selected settings.

Sewage system

The Bosch washing machine drains the waste water after washing and rinsing into the sewer. If the drains are clogged, the washer will not drain .

You need to check how the water drains from the bathtub and sink. If there is difficulty, then the sewer needs to be cleaned.

It is very simple to check whether the reason for the lack of drainage is the sewer system - just pull the end of the hose out of the connection into the drain system and throw it into the sink or bathtub. If the water flows freely, then the problem is a clog in the sewer system of the entire apartment. You can fix it yourself, or call a plumber to do it.

Drain filter


A clogged drain filter can cause the washer to be unable to drain water. Users of Bosch washing machines often forget to clean this unit on time.

It is designed to hold small debris that accidentally gets into the drum, and from it into the washing machine tank. Often there are coins, paper clips, keys, lint from things, etc.

All of these are potentially dangerous items for the washing machine, which can lead to blockages and damage to components. You can clean the filter without disassembling the washing machine, since access to it is at the bottom of the front panel of the machine.

When cleaning the filter, water always spills onto the floor underneath it . If the tank is empty, little water will come out, but if there is any water left, all of it may end up on the floor. To avoid stress, you need to take care of rags and a low container for collecting liquid in advance.

If there is water in the washing machine, but when unscrewing it does not begin to flow out, the cause of the failure is a clogged drain system in the washing machine.

You can watch the video on how to clean the filter in Bosch:

Hose

The drain hose must be positioned freely and not have any crushed areas . For example, due to tightly pushed furniture. At the same time, it must be raised above the level of the tank to prevent self-draining of water.

If, due to carelessness, the drain hose is crushed, bent or otherwise deformed, the water may not drain from the washing machine, or may drain very slowly. The solution to the problem is to position the hose according to all the rules and inspect its surface.

Despite its fairly high strength, the hose can be damaged if handled carelessly. In this case, it should be replaced with a new one.

The problem is within

If the problem with the drain is not solved by simple measures, you will have to move on to diagnosing the nodes in the device itself. To do this, it will be necessary to partially disassemble the Bosch washing machine.

The drainage system - pipe, pump, drain hose - is subject to analysis .
They need to be checked for functionality and possible blockage. The next stage of analysis is the water level sensor. At the final stage, you need to diagnose the control module and the condition of the wires.

Checking the machine after repair

After the repair work has been carried out, it is necessary to check the integrity and serviceability of the mechanism of the Bosch washing machine. First, you should visually inspect and check the assembly and connection of wires to the pump.

After this, the Bosch machine needs to be started and the washing process cycled through in all modes. If the mechanisms are in good working order, you should disconnect the unit from the network, tilt it back and check the integrity and tightness of the connections, and eliminate the presence of leaks. If some connections have a leak, then you need to fix it by carefully inspecting all the parts and the pump. After checking, the washing machine is ready for further use.

To prevent breakdowns of the drainage system in Bosch Classic 5 models, you need to check the clothes before loading them into the drum. Small parts and objects can clog the filter and pump, causing the spinning and draining process to stop.

In case of serious damage, you should contact a repairman or service center. Troubleshooting yourself in some cases can lead to more serious damage. Timely prevention and careful handling will extend the life of your Bosch washing machine.

What to do?

To analyze the components that are involved in the process of draining water, the Bosch washing machine will have to be disassembled, since the main part of the components involved in draining is located behind the front panel. Such work should be carried out with communications turned off. You need to take care of the tools in advance.

Pump, pipe


The pipe is responsible for draining water from the Bosch tank. If this unit is heavily clogged, the liquid will not drain.

This situation can arise when washing items with long pile, if the lining of the jacket is torn and all the fluff or holofiber ends up in the drum.

In order to restore the passage of the pipe, it is necessary to partially disassemble the washing machine. Before you start working, you need to drain the water from the machine and clean the drain filter.

The pump is another important part in the drainage system , which can break down and become clogged. The impeller, which is part of the pump, has blades, thanks to which water is discharged from the washing machine into the drain. If foreign objects get into them, the part may break.

In this case, as in case of burnout, it is replaced. If there is a blockage, clean it carefully so as not to damage the blades. The most convenient way to access the unit is through the bottom of the machine.

Water level sensor

The pressure switch in the Bosch washing machine is responsible for determining the water level in the tank. It rarely breaks in Bosch washing machines.

If it fails, it does not recognize that there is still water in the machine and does not transmit the corresponding signal to the control module. To restore the functionality of the washing machine, this part is replaced.

It is convenient to access the water level sensor by removing the top cover from the washing machine.

Control block

The control module coordinates the operation of the components of the Bosch washing machine. If elements burn out in it, control signals stop being transmitted. In a situation where there is no drain, the required command does not arrive from the board to the pump.

The control unit can be repaired in almost all cases. If there are significant defects, replace them.

For diagnostics, the control module is removed from the washing machine. To access it, you need to remove the top panel, pull out the powder dispenser and remove the control panel.

Wiring


Damaged wiring and loose terminals can cause signals to stop passing between nodes. Moreover, even if both the control module and the drainage system are in good condition, the water will not begin to drain.

To solve the problem, the body of the washing machine needs to be opened and the condition of the wiring analyzed. If breaks or loose contacts are detected, repairs are carried out .

Over time, any equipment in the house breaks down or malfunctions, and large equipment is no exception. For example, a Bosch washing machine does not drain water or, on the contrary, immediately drains it. In such a case, be sure to call a repairman who specializes in such breakdowns.

Major damage to the washing machine

Service technicians for this equipment identify several basic breakdowns of Bosch :

  1. The machine does not drain water. Every housewife begins to panic when the washing machine does not drain the water; she does not know what to do in this situation and does not understand why this could happen. Repairers claim that this is mainly due to a clogged drain hose. To prevent this from happening, you should clean the drain pump filter at least once a year. In addition, it happens that water does not flow out of the hose, in which case you should check the installed program; perhaps a non-draining mode was used.

If the hose is in order and the mode is set correctly, but the washing machine does not drain the water, the reasons may be a failure of the electronic control unit, a wiring problem, or a broken drain pump.

  1. Water does not fill into the machine. This problem is very common, and the cause is low water pressure. This may be due to the water supply tap from which the machine is powered being shut off or the valve being in a faulty position. There is also another reason, but much less frequently - a malfunction of the control unit. This may be due to a power surge.

If such a problem occurs when water has already been collected and the powder has been poured in, then after that you should clean the filter so as not to encounter another type of breakdown.

  1. The drum does not spin. Today's automatic machines have an overload protection system. That is, if you put more things into the machine than you should, the device simply won’t start until you remove the excess. To understand that there is enough stuff, you can spin the drum; if it rotates freely, you can turn on the machine.

Of course, there are other reasons:

  • The drive belt may break;
  • the heating element will burn out;
  • the tachometer fails;
  • the pump does not work;
  • the motor broke down.

The last reason for the breakdown is very serious and will require significant costs. If the control module is damaged, then you should reflash it or change parts.

  1. The water does not heat up during washing. In order to understand that the machine is not heating the water, you can simply place your palm on the hatch about twenty minutes after the start of washing. If the glass is warm (hot), then everything is fine, there is no reason to worry. But if the glass does not heat up, then you need to look for the problem.

Of course, it happens that the wrong program is selected by mistake, but basically the breakdown lies in the heating element. Then you will have to change it. The cause of breakdown may be hard water.

  1. During operation, the Bosch washing machine begins to knock. When you just purchased an automatic washing machine and it started making noise during the first wash, turn it off and check to see if all the shipping bolts have been removed. They do not allow the machine to stand stably, and because of them the machine can even jump around the entire bathroom.

The following reasons are also possible:

  • The machine was installed unevenly;
  • A foreign object or part has entered the tank;
  • The laundry was placed unevenly on the drum;
  • There are too few things included in the device;
  • Bearings or seals have failed;
  • The counterweights have become loose.

The washing machine may also start knocking due to a broken drain pump or a clogged filter and drain pipes.

  1. The washing machine does not turn on. Make sure that there is current flowing into the network, the surge protector or sockets are working properly, and the water is flowing well. If everything is fine with this, then check the electronic module, it may have generated an error.

The most common mistakes:

  • The loading hatch is open;
  • No water supply;
  • Water flows out;
  • Water flow sensor is broken;
  • The lock is faulty;
  • The mains voltage is too high or low.

After a malfunction appears on the monitor, you should turn off the machine for about twenty minutes and then try to turn it on again. If the machine worked, then the system was simply temporarily out of order. When the problem reoccurs again, then you need to contact the repair service.

A faulty motor or a broken drive belt can also cause a breakdown.

  1. The washing machine fills and drains water . The first reason may be an incorrect connection to the sewer (drain). In this case, the water is drained immediately after filling. This can happen immediately after connecting the machine and after some time. It is difficult to name the second reason, most likely some kind of breakdown occurred. To do this, you should call a specialist, who can be ordered on the website.
  2. Water is flowing under the automatic machine. The reason may be the selected program, due to which the powder foams heavily. As a result, a lot of foam is formed, which will cause the formation of a puddle under the machine. It is also possible that the pipe is leaking or the hatch cuff has ruptured. In rare cases, it happens that the drum itself leaks.

Rules for extending the life of a Bosch machine:

  1. Try to install the washing machine on a flat surface;
  2. Plug directly into the outlet itself, avoid the use of tees and adapters;
  3. Wash according to the washing cycle and fill the tank according to the operating instructions;
  4. Clean the drain hose and filter;
  5. It is advisable to wash up to twice a day, with an interval of at least half an hour between them.

Take care of your washing machine from the very beginning of its use, so that in the future there will be no questions: “ why the washing machine does not drain water ” or other equally serious ones. In any case, if you don’t know the exact cause of the breakdown, call a technician who understands this technique. To call a technician to your home, you don’t have to go to the company where you purchased the automatic car; all you have to do is leave a request on the website. A specialist will not only identify the cause of the breakdown, but can also extend its life.

Forced drain

If there is no drain, the items inside the drum remain in the water. This is not a desirable situation both for the Bosch washing machine itself and for the laundry. Even if a repairman has already been called, it is advisable to drain the water from the tank and remove the laundry.

Forced draining is possible in several ways. One option is through a filter. Self-draining can also be done. This method is suitable if the problem is not a clogged pump, pipe or filter.

Forced drainage is implemented in the following way:

  1. Prepare a basin and rags.
  2. Lower the entire length of the drain hose to the floor.
  3. Pull the end of the hose out of the tap into the sewer pipe and lower it into the basin.

You can clearly see how to perform the forced drain procedure in the video:

How to change the pump yourself

When your device does not spin or drain water, but you have made sure that all the parts and wires that we have already talked about are not clogged or unusable.

The pump is probably broken.

Of course, it is better to entrust diagnostics and repairs to a certified specialist, but if you want to fix the problem yourself by replacing the main element in the washer, here are some tips on how to do it:

  1. First you need to get to the pump. To do this, disconnect the drain assembly where the pump is located from the device;
  2. Separate the pump from this assembly;
  3. Carefully disconnect the wiring supplying power;
  4. Install the new element and connect it to the wiring in the same order;
  5. Secure the drain assembly in its original location;
  6. Plug in the machine;
  7. To make sure that the water drains, perform a test wash;
  8. If all these steps do not solve the problem and the water does not drain from the washing machine, contact the service center, since you are unlikely to be able to independently diagnose the cause of the stagnation.

Call the master

It is not always possible to fix a malfunction of a Bosch washing machine with a drain on your own.

If you don’t have the skills, tools or free time, you can contact a washing machine repair company. Such companies can be found on the Internet. Based on customer reviews, you can identify companies that are trustworthy.

The cost of the work depends on the severity of the breakdown and the company’s price list. On average in Moscow, prices start from the following figures:

  • filter cleaning – 1300 rubles;
  • replacement of the pressure switch – 2000 rubles;
  • repair of the control module – 2500 rubles;
  • replacement of the drain hose - 1,500 rubles.

If parts need to be replaced, their cost will be paid separately.

A little about technology and the human factor

When mentioning Maxx, as well as its predecessors, it should be noted that this is one of the best models, distinguished, first of all, by high reliability. But any masterfully developed technical scheme in practice is incomparable with the power of the human factor.

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

  • clean the contents of the item’s pockets;
  • check the fittings for secure fastening (if there are no guarantees, wash them in a bag);
  • Carry out maintenance once a year.

Taken together, a washing machine - in our case Bosch Maxx - is a device that runs a drum with laundry in a certain mode for automatic washing, 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 often gets clogged.

Moreover, it can become clogged thanks to its owner and due to washing specific items. For example, bedding for cats, dogs, woolen items. This also affects the popular Bosch WFF 1201 washing machine, which also often does not drain water for pet owners. Typically, users who are faced with the use of highly contaminated items complain more often.

Microfibers that are washed out of the fabric eventually accumulate in the filter and lead to its complete clogging. To avoid this, the manufacturer came up with annual free(!) maintenance, which should accustom the owner of household appliances to perform mandatory actions. Namely, to call a certified technician to inspect and maintain the machine. Both cars and Bosch washing machines require maintenance, despite their notorious reliability. At the same time, the modern user is incorrigible.
