Repair and check the washing machine motor
There are many factors that can lead to the breakdown of the washing machine. Among them are factory defects, non-compliance with the rules of operation, bad tap water, low-quality detergents for washing, etc. At the same time, the problems can occur in different parts of the machine. Some elements are easy enough to repair, some will require professional intervention, and there are parts that in the case of malfunction are not to be repaired, and need to be replaced.
The motor is the most important element of a washing machine, without which it simply will not work. Engine breakdown is considered a serious malfunction, for the elimination of which it is customary to call a master. In this article, we will tell you how you can check this device at home, without going to the service center.
Types
The first thing you should do before starting the diagnosis is to determine what type of motor is installed in your washing machine. In total, there are several types of motors that manufacturers use to equip washing machines. We present brief information about them in the form of a table.

Ways to check
There are two ways to check the serviceability of the washing machine motor yourself. In order to be able to use them, you need to have at least a basic understanding of the structure of the motor and how it is powered. You can find many diagrams on the Internet that show this important information in an accessible form.
- The first way of checking involves applying voltage to the starter and rotor windings of the motor, having previously made alternate connection of these elements. The disadvantage of this method is that it does not guarantee a 100% result, because even if the motor will rotate under voltage, it does not mean that it will function properly in different modes of the washing machine.
- The second way will require special equipment, namely an autotransformer with a capacity from 500 watts. With the help of this device, it is necessary to energize the connected windings of the starter and rotor. This method is safer, as it allows you to keep the speed of rotation under control.

The video will tell about how you can diagnose engine faults yourself, without calling a master at home.
- If, after diagnosing the engine, you have come to the conclusion that it is necessary to replace the electric brushes, you should not buy the first option you find. Experts advise to look for original spare parts from the manufacturer, as the brushes of another model, most likely, will not fit your washing machine.
- When checking the motor, you need to take care that as a result of the test it did not fail due to voltage fluctuations. To do this, it is recommended to connect an additional element to the circuit, such as a heating element or a light with a high enough power.
