The electric motor is one of the central links of any washing machine. He is responsible for the drum speed during washing, rinsing and spinning. If the motor stops working, the wash will not start. Therefore, many users are concerned with the question: is it possible to remove the washing machine motor with your own hands in order to repair or replace it?
If you already have repair skills household appliances, then disassembly washing machine It won't seem complicated to you. The main thing is to take into account the type of washing machine, since the motors in this technique can be different: an asynchronous motor without brushes, a regular commutator motor or a direct drive motor.
In this article you will find instructions for dismantling the motor with photos and videos.
In modern washing machines Manufacturers install inverter motors, estimating their performance at 10-15 years. Therefore, such electric motors break down extremely rarely. This means you have a SM with a traditional commutator motor.
Typically these engines suffer from the following breakdowns:
- The brushes wear out, which leads to a loss of power from the electric motor.
- It breaks the winding.
- The lamellas wear out, which also affects the power and stability of the part.
To be 100% sure of the nature of the breakdown, you need to remove the electric motor and check it. It is important to do this correctly so as not to further damage the machine.
Important! The lion's share of all motor breakdowns is caused by brushes. Problems with the winding occur less frequently, and only occasionally the problem concerns the lamellas.
To remove the engine from the washing machine, you should follow a clear procedure, stock up necessary tool and take photos or videos. This is necessary to capture the location of the wires and then put everything back together without any problems.
How to change the motor? Follow the instructions:
Now you can repair the engine (see article “”) or install a new one.
To replace the electric motor with a new one, buy in advance original analogue and install it in reverse order, connecting all wires correctly. After assembling the washer, run a test wash to make sure your actions are correct.
