Why does it not draw water and how to troubleshoot a Bosch washing machine?

During the operation of washing equipment, you may encounter various problems, some of which can be eliminated on your own.

One of the common problems with washing machines, including Bosch ones, is the lack of water supply, which makes the washing itself impossible.

Why the Bosch washing machine does not fill with water and how to fix this problem in operation, we will tell you further.

Water does not flow into the washing machine - reasons

The lack of water supply in Bosch can be the result of many reasons, including User errors are not uncommon or problems that are not even directly related to the washing machine:

1. Lack of water in the water supply.
2. The water supply tap to the washing machine is closed.
3. A squashed water supply hose.

In more complex cases, Bosch will not be able to do without repairs. Such situations include:

• water supply valve malfunction;
• problems in the control module;
• pressostat malfunction;
• UBL malfunction;
• filter clogged.

Carrying out diagnostics

As with any failure, you should start analyzing the situation with simple causes and nodes, which can be easily diagnosed.

First, you need to check whether there is water in the apartment’s water supply system.After this, you need to make sure that the water supply tap to the Bosch washing machine is open.

Next in line is the water supply hose. It should be positioned freely, without kinks or areas compressed by heavy objects. Despite the reliability of the material from which it is made, deformation and damage are possible. If its condition is poor, the hose is replaced with a new one.

In the event that the problem cannot be solved in a simple way, you will have to partially tear the body apart and start checking the components, which are involved in the water supply process.

If there is a failure during the water supply process, the Bosch washing machine may display the corresponding error code on the screen, by analyzing which you can understand what the problem is. For example, E17 or F17 they talk about exceeding the time allotted for drawing water, E16 talks about the hatch door being unlocked, etc.

Ways to solve the problem

To diagnose and repair a Bosch washing machine, you need to disconnect it from the electricity supply and turn off the water supply tap. The washing machine is pulled out from the wall so that you can approach the device from all sides. After this, remove the back wall and top panel.

Filter clogged

Checking the mesh filter, which is located at the connection between the inlet hose and the Bosch washing machine (from the rear wall), can be carried out without disassembling the washing machine. If there is water in the water supply, the tap is open, and there are no problems with the hose, you need to inspect the filter mesh.

If it is very dirty, clogged with scale, an old toothbrush will help in cleaning. After washing, the mesh is put back in place and the hose is carefully secured.

The hose is clogged

In rare cases, the Bosch inlet hose may also become clogged.. This situation is possible when very dirty water comes from the water supply.

This can happen, for example, after the repair of water supply networks, when fragments of rust and other fractions of small debris are supplied to consumers with water.

To check the hose, it is disconnected from both the water supply and the washing machine. You can even establish its passability by blowing into it from one end. A clogged hose can be cleaned or replaced with a new one.

Breakdown of the pressure switch

The water level sensor controls the amount of water in the tank. In the event of a malfunction, reliable information is not transmitted from this element to the Bosch control circuit. As a result, the water does not collect and the wash does not start. In some cases, if a blockage is the cause of the problem, the pressure switch can be repaired, but most often it is replaced with a new one.

The water supply valve is broken

The water supply valve in Bosch washing machines allows you to fill in water that comes under high pressure. The signal to open it comes from the control module. If the valve malfunctions, water intake does not occur. If a part breaks, it is replaced with a new one.

Control module failure

A malfunction of the Bosch control module may be caused by burnout of elements on the board and tracks. If this situation occurs, then the valve does not operate due to the fact that the signal from the control unit simply does not arrive.

To accurately diagnose the Bosch module, it must be dismantled and tested in a workshop. The master replaces the burnt-out elements with new ones and resolders them.

It may be necessary to reflash the module or even replace it completely.. The latter option rarely happens, and is typical for cases of significant burnout of the block, when it can no longer be restored.

UBL malfunction

In order for the wash to start and the water to fill up, the Bosch washing machine needs to lock the hatch door.

In the case when the hatch is closed, but the electronic lock is not activated, water intake into the washing machine does not begin.

In such a situation, the washing machine may display the corresponding error code on the display. The solution to the problem is to replace the damaged part with a new one.

The pump is broken

If the drainage pump breaks down, water supply to the Bosch washing machine of some models does not start. The problem requires analysis. The part may need to be cleaned or replaced.

Wiring violations

If the wiring is faulty, signals do not pass between the Bosch control unit and the nodes that are involved in drawing water. To determine the problem area, the technician performs a detailed inspection. If necessary, the cable is replaced and the contacts are soldered.

Leak

If the Bosch washing machine starts drawing water and then stops working, there is a possibility that Aquastop will trigger. This circumstance is usually indicated by the error code corresponding to this failure - F23 (E23). In the case when the stop of pouring water into the tank is caused by a leak, it is necessary to eliminate the causes of the leak, after which the work with starting the wash will improve.

Call the master

The problem with getting water into a Bosch washing machine is not always solved on your own. In case of serious failures, experience, knowledge and special tools are required.

The average cost of repair work in Moscow is:

• replacement/repair of pressure switch – from RUB 2,000;
• repair of the control module – from 2,500 rubles;
• wiring repair – from RUB 2,000;
• hose replacement – ​​from RUB 1,500. etc.

If the washing machine is under warranty, then you cannot open its case yourself. All repair work in this case must be carried out by service center technicians.

Prevention

In order not to encounter a situation where water does not fill into the Bosch washing machine, preventive measures should be used.

These include the following:

1. If the water in the water supply is heavily polluted and has foreign inclusions, then it makes sense to install a water filter in your apartment.

   This will prevent scale and other contaminants from entering the washing machine, which will extend the life of the machine.

2. Frequent power surges in the electrical network can lead to burnout of elements in the control unit and to expensive repairs.

   Installing a voltage stabilizer and connecting Bosch to the network through it will help prevent equipment breakdowns.

3. Compliance with the rules for using a washing machine is the most basic preventive measure.

Conclusion

In cases where the Bosch washing machine does not draw water, it is necessary to determine the source of the problem and carry out repairs. If repairs on your own are not possible, washing equipment repair specialists will come to the rescue, who will restore the functionality of the device and issue a guarantee for the work performed.
