Why won't my Bosch washing machine drain and what should I do?

Household appliances of the Bosch brand have long and deservedly enjoyed a reputation for being reliable and durable. Unfortunately, it can also fail. Perhaps the least serious deviation from the norm is the loss of the unit's ability to drain water. There may be several reasons for the malfunction. In some cases, you will have to seek the help of specialists, but sometimes the problem can be eliminated on your own.

Disruptions in the operation of the drainage system usually do not appear suddenly. The Bosch Maxx 5 automatic washing machine (one of the most popular models today), and any other model, when switching to the spin mode, begins to drain water more slowly. If you do not pay attention to this, then the drain may stop altogether. The first signals of a malfunction may be:

• removing water not after each operation (initial wash, main wash, rinse, spin);
• failures in starting the next operating mode of the unit;
• when rinsing, the washing machine does not drain the water, in which the rinse aid may also be dissolved;
• blocking the spin mode, while the laundry remains not just a little damp, but a lot of water remains in it;
• water does not drain, you can hear a continuous hum during washing.

The statistics of calls to repair shops and service centers due to the fact that the drain of the washing machine does not work, in the overwhelming number of cases confirms the high probability of this malfunction due to incorrect user actions. The Bosch Classixx washing machine, like any model of this manufacturer, is very tolerant of the actions of its owner and is able to smooth out many, but not all of his rash actions.

• The wrong wash mode is selected.
• The filter or drain hose is clogged with small objects not removed from the pockets.
• Frequent overloading of the drum by linen.
• Washing of clothes soiled with pet hair without preliminary cleaning of the linen.
• Washing very dirty items without first removing the dirt. These can be building materials, earth, sand, etc.
• Blockage of the sewer system of the apartment.

Of course, factors that are independent of the user may also be among the reasons:

• poor quality drain pump pump;
• damage to the water level sensor or the control unit of the washing machine due to a voltage drop in the electrical network;
• poor quality detergents (powder or conditioner).

Of course, finding out the reasons is better to start with what happens more often and is easier to fix. First of all, you should check the condition of the filter. For access to it, a small hatch is provided, the lid of which is located below the hatch for loading linen on the front panel of the washing machine. Before opening the lid, it is better to familiarize yourself with how this is done according to the instructions, since different Bosch models differ somewhat in the device of this simple unit.

The filter must be unscrewed. This should be done carefully, after reading the instructions. Typically, the thread travel of the filter plug is quite tight. When the filter is removed, water will start pouring out of the tank and nozzles, you need to be prepared for this. The filter is easy to clean. Large objects and fluff are removed by hand, then the filter is rinsed under running water. After removing the dirt, the filter can be replaced. In this case, all operations are performed in the reverse order.

One of the signs of a pump malfunction may be a dull hum when there is no water drain. In this case, if the user is not sure of his capabilities, it is better to call the wizard. However, the device of Bosch washing machines still suggests the possibility of eliminating this malfunction on your own, of course, with certain skills.

With the filter removed, you can examine the condition of the drain pump impeller. To do this, you need to use a flashlight. If threads, hair or pieces of fabric are wrapped around the pump shaft, remove them. It is not always possible to reach the shaft with your fingers; sometimes you have to use tweezers. At the same time, the condition of the impeller blades can be assessed.

In addition to mechanical damage, the pump motor may fail, then there will not even be a hum in the water drain mode. The cause of this malfunction can be a drop in the mains voltage or simply a very long operation of the device.

Replacing the pump will require strict adherence to the instructions. Using pliers, you will have to disconnect the drain pipe. Sometimes the cause of the malfunction may be hidden in it. It can become so clogged that it practically ceases to let water through. Removing dirt is usually not difficult; this can be done, for example, with a screwdriver, it is important not to damage the walls of the nozzle. Then it must be rinsed under running water.

The cleaned nipple is installed in place. Sometimes, if the electric motor has not burned out, this may be enough to restore the functionality of the drain system. If the drain pump electric motor is faulty, its self-repair is hardly justified. In this case, it is better to contact the service organization immediately.

After carrying out preventive or repair work of the drain system of the washing machine, it is necessary to make sure that the unit is in good working order. The procedure looks like this in general terms.

• Visually assess the condition of all fasteners: clamps and mounting screws. This is necessary to avoid smudges.
• Make sure that the wires are connected correctly and securely.
• Start washing as usual.
• If the fault has been rectified, check the tightness of the connections again.
• If there are leaks, once again examine the condition of the units, as a result of dismantling, subtle cracks may appear on them, in which case the unit will have to be replaced.
• If after a secondary inspection no smudges are found, you can test the machine in different operating modes.
• If, as a result of the secondary testing, there are no deviations from normal operation, the machine can be considered serviceable and begin to operate as usual.
