Common reasons why the washing machine does not pick up speed

Worn bearings 

The cause of the fact that the washing machine does not spin and the drum does not rotate properly, can be worn bearings. In this case, the more neglected wear, the more difficult it is to rotate the drum. In the most severe cases, the drum stops rotating completely. Among other things, the danger of worn bearings is that they can lead to related breakdowns that can be much more serious and expensive to repair.

 

Signs that the drum does not rotate properly because the bearing unit is worn are parallel noise and rumbling as it rotates, the drum may also be very loose, chattering. The cause of wear and destruction of the bearings may be water penetrating them through a poor-quality gland. Water on the bearings provokes corrosion, which destroys the bearing structure. You should also not rule out natural wear and tear, if the washing machine has been in use for a long time, for example, more than 7 years.

 

It is necessary to change the entire bearing unit at once – both bearings and the oil seal. Only an experienced master from the service center should be entrusted with this work since this work requires complete disassembly of the equipment. Also during the work, you may encounter certain difficulties, such as a non-disassembled tank, which will have to be sawed and then re-glued and bolted together again.

 

Malfunction in the control module 

Unexpected behavior of the washing machine as a whole can be caused by a faulty control module. This is a very important unit of the washing machine, which is often called the “brain” of the device. The board receives all the data from sensors and input information according to the modes and programs selected by the user. In turn, the control board triggers certain processes in the operation of the washing machine.

 

One of the possible outcomes of the board breakage is when the programs get disrupted during the washing process, and during the spin cycle, the drum will not reach sufficient speed. Error codes will often appear on the device display (if available). The control module often fails due to an unstable power supply, short circuit, and moisture on the board.

 

To fix the breakdown, you will need a specialized tool – in addition to a screwdriver you need a multimeter, and a soldering station. You also need sufficient experience in carrying out works of this nature. This means that you will need a visit from an experienced master from the service center. He will diagnose the control board elements, identify malfunction, perform resoldering of tracks, and replace burnt-out elements. You may need to replace the entire board in the most complicated cases.

 

Tachometer not working 

The drum of the washing machine can rotate at different speeds. The drum rotation speed is measured in revolutions per minute (rpm). The greatest number of revolutions is achieved during the spin (usually from 800 rpm to 1200 rpm, less often less or more). Accordingly, in the device of the washing machine, there is a sensor that controls the speed of rotation of the drum so that it accelerates to a certain number of revolutions in the required stages of washing. It is called a tachometer.

 

If the tachometer is faulty and does not work correctly, then the drum of the washing machine will not be able to dial in enough speed, because the control board does not receive information from the tachometer and does not give the appropriate command to increase the speed. Most often, the disrepair of the tachometer becomes the impossibility of revolutions set during the spin cycle.

 

Repair in this case is simple enough. If the tachometer breakage is confirmed, it should be replaced with a new one, as repairs are inexpedient. You can replace it yourself, or resort to the help of an experienced craftsman. Nevertheless, it is worth noting that the tachometer fails very rarely. Still, you should always consider it.
