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 resorting to 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..
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 that the water from the washing machine cannot drain. 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.
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 is subject to analysis - pipe, pump, drain hose. 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.
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 tank Bosch. 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 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.
For diagnostics, the control module is removed from the washing machine. To access it, you need to remove the top panel and pull out the dispenser for powder 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.
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:
- Prepare a basin and rags.
- Lower the entire length of the drain hose to the floor.
- 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:
Call the master
It is not always possible to fix a malfunction of a Bosch washing machine with a drain on your own.
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.
Conclusion
If your Bosch washing machine does not drain water, you need to determine the cause of this failure. In some cases, it is possible to deal with the problem yourself, but in case of complex breakdowns, it is advisable to use the help of a specialist.
