There are a number of factors that can lead to a breakdown of the washing machine. Among them, factory marriage, non-compliance with the rules of operation, poor tap water, substandard means for washing, etc. In this case, malfunctions can occur in different parts of the unit. Some elements are easy to repair, some require professional intervention, and there are spare parts that, in the event of a malfunction, can not be repaired, but need to be replaced.
The engine is the most important element of the washing machine, without which it simply can not work .A motor failure is considered a serious malfunction, for 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 contacting the service center.
Types of
The first thing to do before starting a diagnosis is to determine which type of engine is installed in your washing machine. In total there are several types of engines that manufacturers use to equip impellers. We present brief information about them in the form of a table.

Testing methods
There are two methods that allow you to check the serviceability of the washing machine motor yourself. In order to be able to use them, you need to have at least an elementary idea of the device of the engine and how its power is going. On the Internet, you can find many schemes that display this important information in an accessible way.
- The first test method involves supplying voltage to the starter and rotor windings of the motor, having previously made the alternate connection of these elements. The disadvantage of this method is that it does not guarantee a 100% result, because even if the engine rotates under voltage, this does not mean that it will function properly under different operating modes of the washing machine.
- The second method will require special equipment, namely an autotransformer rated at 500 watts. With this device, you need to supply the connected windings of the starter and rotor. This method is more secure, since it allows you to keep the speed of revolutions under control.
Reasons for breakdowns and how to solve them
| Cause | What should I do? |
| Breakage of lamellas( plate-contacts) in the collector |
|
| A break in the winding of the rotor or starter |
|
| Wear of |

The video will tell you how to diagnose engine faults yourself without causing the master to go home.
- If, after diagnosing the engine, you have come to the conclusion that it is necessary to replace electric brushes, do not buy the first available option. Experts advise to look for original spare parts from the manufacturer, as brushes of another model, most likely, will not fit your washing machine.
- When checking the engine, care must be taken to ensure that the test does not fail due to voltage fluctuations. To do this, it is recommended to connect an additional element to the circuit, for example, a heater or a lamp with a sufficiently high power.
