Bosch washing machine does not spin

What to do if your home assistant does not spin out the laundry after a wash cycle? Automatic machine users ask this question quite often. Let's try to understand all the reasons for this malfunction and tell you how to fix it using the example of a Bosch washing machine.

Custom Reasons

Most often, a Bosch washing machine does not spin if the user makes a mistake when choosing a program or violates simple operating rules. Washing programs designed for delicate clothes and linen are initially set so that there is either no spin at all, or it takes place at the lowest speed. Therefore, you should not be surprised if you take too wet laundry out of the drum after the Silk mode.

The second reason is that the user inattentively set the spin speed on the washing machine, turning off the spin cycle completely. In principle there is no problem. It is enough to wait until the end of the washing program and turn on the spin function separately. This function on Bosch washing machines is indicated by a spiral.

The third reason is the discrepancy between the weight of the laundry and the maximum load of the drum and its volume. You cannot overload the drum, just as you cannot underload it. An unwrung down jacket is a consequence of an overload of a washing machine with a small volume, and wet organza curtains are, on the contrary, an underload.

Technical issues

If the above reasons are not your case, then you need to look for a breakdown. The lack of spin can be caused by:

• Faulty tachometer,
• Faulty water level sensor,
• Broken electric motor,
• Clogged filter or pump,
• Failure of the electronic module.

We will talk about finding the above faults in more detail in the next paragraph. And now I would like to talk about the specific design features of belt-driven washing machines, including Bosch. The fact is that with such washing machines, the belt stretches a little over time and can no longer provide stable transmission.

Some people will ask: what does the spinning problem have to do with it and what does the drive belt have to do with it? In fact, the relationship is very direct. An elongated belt leads to the fact that the electronic module receives information about revolutions from the tachometer, which does not correspond to that contained in the base. As a result, a malfunction occurs in the electronic module, which causes the program to stop just before spinning. The solution to the problem is to tighten the belt or replace it. By the way, if you don’t have a Bosch, but an IFB washing machine doesn’t spin clothes, the reason may be exactly the same.

Troubleshooting

If the Bosch washing machine refuses to spin out the laundry, or indeed to activate this stage of the washing program, you need to start by unscrewing and inspecting the garbage filter. Cleaning the garbage filter is a mandatory procedure for any automatic washing machine, and if it is neglected, it can result in problems with draining water and starting the spin program.

Next, we need to turn off the washing machine and take it out to a place where we can safely disassemble the home assistant. We take out the powder receptacle, place the washer on its left side and remove the tray. From below we get to the drain pipe and pump. We unscrew the clamps, pull off the pipe and inspect it. We remove the pump, disassemble it, and inspect, first of all, the impeller. After this, take a multimeter and check the resistance of the unit.

If everything is fine with the pump, you should immediately check the engine since it is relatively convenient to get to it through the bottom. We remove the brushes, if they are intact, check the resistance of the motor winding.

Having checked the engine, we proceed to the tachometer of the Bosch washing machine. The Hall sensor is located directly on the motor housing of the washing machine; we also reach it through the bottom, remove it and check the resistance. If the sensor does not ring, it is replaced with a similar one.

Now let's check the pressure switch.

• We unscrew the screws that hold the top cover of the Bosch washing machine.
• Remove the top cover.
• We find an object similar to the one shown in the figure below, this is the water level sensor.
• We thoroughly clean and blow through its tube, and then measure the resistance; if a breakdown is detected, the pressure switch must be changed.

The worst thing is if, in the end, troubleshooting leads you to the control module of the Bosch washing machine. It is necessary to find out which of the triacs has failed, and to do this, having only ordinary experience in handling electronics, is very difficult, almost impossible. You will have to contact a qualified technician.

Prevention

Any equipment tends to break down periodically, and nothing lasts forever, but oddly enough, a person can make a Bosch washing machine last longer than usual without breakdowns. How to do it? Everything is very simple; you need to follow the rules that the mechanic constantly talks about. And which, with the same unenviable consistency, are ignored by users of washing machines. These are the rules.

• Do not throw clothes into the washing machine drum without first checking the pockets and removing any foreign objects that could get into the tub and subsequently cause a blockage.
• Place a medium amount of laundry in the drum. It is very important not to overload the car, but also not to idle. For example, if your Bosch washing machine has a load of 6 kg, then you need to wash from 2.5 to 5 kg - this is optimal. This measure will allow the engine and drive mechanism to last as long as possible.
• Run the washing machine at least once a month. If for some reason the washing machine sits idle for a long time, its rubber bands will become unusable, which in turn will force the user to pay for repairs.
• Do not pour too much powder into the powder container. Remember, the washing machine will not appreciate your generosity; on the contrary, excess powder will clog the pipes and the pressure switch tube, which will lead to breakdown.
• If possible, purchase a voltage stabilizer and henceforth connect the washing machine to the mains only through it. This measure will protect the sensitive electronics of the washing machine from many risks.
• After finishing each wash, do not forget to carry out routine care of your home assistant: wipe the cuff of the hatch and the powder receptacle with a cloth, open the hatch wide for drying and pull out the powder cuvette, unscrew the garbage filter and drain the remaining water so that it does not stagnate.

To summarize, we note that the Bosch washing machine, despite the myths about the reliability of washing machines of this brand, periodically breaks down. In particular, often the machine simply refuses to spin the laundry. We discussed the reasons for this behaviour on the page of this publication, we hope the information will be useful to you!
