Typically, the machine obediently carries out the command given by the user: washes clothes, rinses, spins, and notifies about the end of the process. An abnormal situation is when the washing machine does not stop, although the program should have completed long ago. What to do if you notice your home assistant is freezing? What could be the problem, how can I help the machine finish washing?
The “intelligence” of washing machines is quite developed. Several special programs are programmed in the memory, differing in water heating temperature and spin speed. Also, depending on the selected mode, the cycle duration changes. If the washing machine does not stop after the time set by the “brain,” then you need to look for a breakdown.
After waiting an extra hour after the moment when, according to plan, the washing should have ended, you can drain the water from the tank with your own hands (through the drain filter), open the door, and take out the laundry. It is important to test your Bosch washing machine to understand exactly at what stage of the cycle it slows down.
So, you will have to turn on the machine again and run the shortest program. After this, you need to observe, you will find out that:
If you analyse the symptoms of illness of a Bosch washing machine, then it is quite easy to narrow down the range of breakdowns of the machine. Once the malfunction has been determined, equipment repair should begin.
First you need to check if there is water pressure in the tap. If it barely flows, this would be a logical explanation for the delay in washing. We will have to wait until the supply is restored. In some cases, this will be the solution to the problem.
Another reason for eternal washing may be an incorrectly connected drainage hose. If it is simply stretched across the floor, water can be drawn into the tank and immediately go down the drain. The level sensor will send a signal about the shortage, the liquid will begin to fill again and instantly go down the drain.
What to do in this situation? The solution is obvious - connect the drain hose correctly. It should be located at a level of half a meter from the floor. If you do not fix it at such a distance, the water will flow away by gravity.
In addition to uncontrollably rapid drainage, the cycle may be delayed due to the reverse. If the garbage filter, pump, or drainpipe is clogged, water, on the contrary, cannot leave the system and the washing stops. In this case, the procedure will be as follows:
If cleaning the drain filter does not produce results, you will have to inspect the pump and pipe. To do this, you need to lay the machine on its side, loosen the clamp securing the tube, remove the pipe from the pump, wash it and put it in place. The drain pump is disassembled, cleaned, and reinstalled.
Taking too long to add water can cause the cycle to slow down. First, inspect the inlet hose - the tube may be kinked or squashed. If everything is in order, you will have to check the incoming mesh filter. The algorithm of actions will be as follows:
To inspect the solenoid valve, remove the top cover of the MAS. You can check the element by applying a voltage of 220 Volts to its coils or using a multimeter. If a malfunction is detected, the device will have to be replaced.
The cycle can continue “indefinitely” due to a broken level sensor. The pressure switch sends incorrect data to the washer’s “brain” or does not work at all. As a result, the control module does not know that there is enough water in the tank and does not give a signal to start washing.
To replace an element with your own hands, you need to:
Simple diagnostics will help you understand whether the pressure switch needs to be changed. To check the part, you should find the water level sensor and remove the tube from it. Then you need to attach another tube of a suitable size to the fitting and blow into it. Clicks should be heard; if not, the element is faulty.
As mentioned earlier, the reason the wash stops may be a broken magnetic valve. It happens that the membrane of the element “wedges” and water does not begin to flow into the tank or is filled uncontrollably. The part cannot be repaired; the coil will have to be replaced. This is done as follows:
Heaters installed in Bosch washing machines are sensitive to hard water. Over time, without proper care, a layer of scale forms on their surface. This disrupts heat transfer from the heating element. It takes a long time for the water to heat up to the desired temperature, so the wash takes tens of minutes.
First step is to remove the heating element. For this:
The heating element is tested with a multimeter. If everything is fine, you can descale it yourself. In the fight against limescale, both “folk” remedies and special household chemicals are equally good. It would be a clever idea to check the temperature sensor. If a thermostat malfunction is detected, it will have to be replaced.
The probable cause of the Bosch SMA freezing is damage to the electronics. The control module does not work correctly when the triac burns out, the firmware fails, or the soldering of the tracks is defective. There is no need to delve into the “brain” of the machine on your own without sufficient knowledge.
You can remove the control unit and inspect it for visible defects. Burnt elements and tracks will be noticeable even to an inexperienced user. It is better to entrust board repair to a specialist.
