Bosch washing machine does not drain water: possible causes, troubleshooting methods

Currently, it is difficult to imagine at least one apartment without an automatic washing machine in the bathroom or kitchen. This device can greatly facilitate physical labor and free up time for the modern housewife. You just need to load dirty laundry, set the required washing program, turn on the machine and you can calmly go about other things.

But how sad it is when, after the signal about the end of the wash, you open the door and notice that the water remains in the drum and the clothes are completely wet. This means that the Bosch washing machine does not drain water. Possible causes and solutions to the malfunction are easy to identify and fix yourself.

Draining process

Removing water from the washing machine tank occurs in the same way, regardless of the model and brand of the unit. Each machine is equipped with a drain pump (pump), which pumps out liquid during the washing process.

On the pump shaft there is an impeller with blades that rotate using an electric motor. The pump is installed in a volute, to which all the parts necessary for draining water (hose, pipes) are connected.

The entire technological process of water removal is controlled by a pressure switch, which serves to determine the liquid level in the tank. Water from the tank is pumped out by a pump through a drain hose equipped with a special cleaning filter and sent to the apartment’s sewer system.

All parameters of the draining process are set and controlled by the electronic control unit of the washing machine.

Symptoms of concern

During the washing process, water is removed from the washing machine tank automatically, several times in one cycle. First, the initial and main wash is performed, then rinsing and spinning the laundry. After each operation, water must be removed from the machine.

To find out why the Bosch washing machine does not drain the water, you need to periodically monitor its condition during the washing process. The presence of the following symptoms should alert you:

1. The process of removing water began to occur periodically, and not after each necessary operation.
2. The water drains slowly, and the next washing mode starts to fail.
3. During the washing phase, drainage occurs, but during rinsing, the Bosch washing machine does not drain the water.
4. The spinning of the laundry is blocked.
5. The Bosch washing machine does not drain water and hums when washing.

Having discovered at least one of these symptoms of improper behavior of your home assistant, you need to establish the cause of the problem and begin to eliminate it.

What to do after purchasing the device?

After delivering the washing equipment home, the first thing you need to do is check whether there are any defects on it. If the machine has any damage, the seller will accept it back without any problems within two weeks from the date of purchase. If you apply later, difficulties may arise. Even considering that the equipment is under warranty.

After checking, you need to install the washing machine in a certain place and unscrew the transport bolts. The place for the machine must be completely prepared in advance.

To do this you need:

• Level and strengthen the base;
• Dismantle unstable floor coverings (laminate, carpet);
• Ensure that the machine is connected to the electrical network, water supply and sewerage;

Bosch Classixx 5 does not require the purchase of various additional accessories. However, to reduce the noise level created when the machine vibrates, it is advisable to purchase anti-vibration stands for the legs.

It is important to note that Bosch Classixx 5 washing equipment must be installed level. Then it will be less likely to fail and create unnecessary problems.

Try to align the unit body perfectly. To do this, you need to place a building level on the machine, then twist its legs one by one until it is level.

For a more detailed study of the process of connecting the machine to communications, you should use the original instructions. Then you can do all the work yourself without much difficulty. However, if you do not have experience working with washing equipment, then it is better to entrust its connection to professionals.

Causes of drain system malfunction

The lion's share of the reasons why a Bosch washing machine does not drain water relates to the human factor. And although the units of this brand are considered one of the highest quality and most reliable washing machines on the market, breakdowns still occur with them.

The Bosch washing machine does not drain water for several reasons:

1. The washing mode is selected incorrectly.
2. The filter is clogged.
3. The drain hose is clogged and does not flow well.
4. The drain pump is faulty.
5. The level sensor is damaged.
6. The unit control unit is faulty.

Therefore, before draining the water from the Bosch washing machine, you need to disconnect it from the network, and then begin to find out the cause of the breakdown.

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.

Clogged filter or pipe

In most washing machines, a filter is installed between the drain pump and the hose, which protects the drain from various debris from entering the unit’s tank, and also helps to save lost items from the pockets of things. Over time, small lint or threads that come off the laundry gradually accumulate and clog the filter.

When the filter becomes completely clogged, the control unit generates a special error code and the Bosch washing machine does not drain water.

It is easy to clean the filter with your own hands. Its location and cleaning methods are indicated in the machine's user manual. Most often, the filter is located at the bottom of the front panel of the washing machine. It is usually covered by a square or round hatch, and on some models there is a decorative panel installed. Its fastening is simple, with latches that are easy to detach. But before you begin to remove the filter device, you need to place rags around the machine to prevent any remaining water from spilling onto the floor surface.

As soon as you manage to unscrew the filter, water will flow from the tank. If this does not happen, it means that the pipe is clogged, which will also have to be removed and cleaned of scale or debris. If there is no debris in the filter and pipe, and the water does not drain, you will have to disassemble the drain pump.

Features of repair of different brands

Different models of Bosch washing machines are similar in design, but the shape, location and fastening of internal components are different. For proper disassembly and repair, you need to know the specific features of the devices, then access to the faulty part can be easily found.

Bosch Maxx 4

To troubleshoot the Bosch Max 4 washing machine, several disassembly methods are used. To get inside the case, remove the panel and control module, you need to take out the powder dispenser, unscrew the 3 T20 star screws hidden behind it, which hold the top panel and front facing. The first element is still fixed on the side with a screw and plastic clips. They are easy to remove, except for the middle retainer. It is loosened by pressing a thin screwdriver from above through the hole in the frame.

To remove the module, you must release the plastic latches. But first, mark all the connectors with a marker - this will make subsequent assembly easier.

Bosch Maxx 6

The top cover of the device is fixed with self-tapping screws for the T20 sprocket, after unscrewing which it moves back along the guides and is removed. Further disassembly is performed as for the previous model. To get to the tank and pipes, you need to unscrew the screws securing the front and middle top strips. The powder dispenser is released and the connected pipes can be inspected.

Bosch Maxx 7

To get to the heating element, release the top cover and front trim in the manner described. All external fasteners are made with an asterisk. But before removing the front wall, you need to unscrew the screws covered by the bottom plastic panel and release the seal of the loading hatch.

After these manipulations, access to the tank, heating element, engine and shock absorbers is opened.

If you have the desire and confidence, then it is possible to repair a Bosch washing machine with your own hands. Not everyone can fix defects in electronics, but you can replace the tubular heater, sensors, pipes and other elements yourself.

Drain pump malfunction

When a Bosch washing machine does not drain water and hums when washing, the drain pump may be faulty. Any washing program is carried out with the mandatory use of this unit. A breakdown of the pump leads to the fact that after all washing modes are completed, water remains in the machine’s tank.

Most often, the cause of a malfunction of the drain pump is the entry of small objects (threads, buttons, hair, coins) into the volute of the unit, which jam or destroy the impeller blades, as well as natural wear of the mechanism parts.

If a Bosch washing machine, both top-loading and horizontal, does not drain water, you will have to remove the pump. You can inspect it by first disconnecting the machine from the power supply and removing the cleaning filter. After removing the filter, you can see the pump impeller in the hole. It should rotate easily by hand. If rotation is difficult, it means that there is thread or fabric wrapped around the shaft.

If there is any mechanical damage to the blades and motor windings, the pump must be replaced. It is necessary to take into account that it is possible to install a pump from a unit of a different brand, the main thing is that it is suitable in terms of mounting and operating power.

Pump inspection and repair

Pump failure can be determined by the specific noise that appears during an attempt to drain. This sound is always a little muffled. The reason for the failure can be either a long service life or debris that has gotten inside the object, blocking the impeller. There are cases when the pump is damaged by threads or hair wound around it. In this case, complete disassembly of the pump will be required. But it is worth noting that it is extremely difficult to independently determine the condition of the part; a specialist can do this much better.

Damage to the control unit and water level sensor

The Bosch Max 7 washing machine does not drain water if the electronic control module is damaged. Then the failed module sends incorrect signals to the control board, which disrupt the draining process.

Damage to parts of the electronic circuit of the control unit can occur due to increased humidity and power surges in the network. In any case, it is not advisable to carry out electronic repair work yourself; it is better to contact the service center specialists.

At the back of the machine, under the cover, there is a pressure switch that controls the amount of water in the tank. Its failure leads to error messages, with the sensor erroneously indicating that there is no water in the machine.

Before changing the sensor, you need to check the functionality of its contacts. Often a simple cleaning of the contact plates will bring life back to the entire device.

Do-it-yourself Bosch PMM repair

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

How to drain water from the bunker? Use the drain hose as described above, or place a container and drain the residue by tilting the dishwasher. Automatic draining is carried out differently in each model; 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 camera door more tightly;
• for SMV, SPV models, pressing the “Start” key for three seconds is triggered.

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

How to check and replace the pump:

Now inspect the pump for blockages. Diagnostics of the electronic part is performed 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 dishwashers it is also attached to the motor. The part looks like a plastic box with a tube and a pressure reservoir. How to replace the pressure switch in a dishwasher, read the article.

The most unpleasant failure is a failure of the control module. A breakdown can occur for various reasons: a sudden surge in voltage, moisture, or a short circuit. It is not the entire unit that can fail, but its individual elements. Then the board can be repaired, but this should only be done by a specialist.

How to get to the electronic unit:

• open the bunker door completely;
• Unscrew the screws around the perimeter from the inside;
• close the door and remove the outer panel;
• disconnect the wiring from the control board;

Inspect the unit for damage.

Now you can contact the master. You should know that replacing a module is not always cheaper than buying new equipment, especially if the dishwasher has already served for 10 years. But if you choose spare parts, buy only original components that will ensure the dishwasher will work for many years to come.

Preventive actions

To avoid premature wear of parts of the washing machine drain system, the following preventive measures must be observed:

• remove small foreign objects from pockets before washing;
• Clean the drain pump filter regularly;
• use a surge protector to protect the electronic part of the machine from power surges;
• observe the drum loading weight specified in the instructions;
• add washing powder according to the norm, while monitoring its quality;
• carefully monitor the correctness of the set washing mode.

Remember that it is better to prevent a breakdown than to spend money on repairs later. Any malfunction always makes a person nervous, and this is dangerous to health.
