Few days ago my 10 years washing machine Beko WM3552M stops to work.
Symptoms: it spins for 1-2 seconds and then nothing happens. The vacuum pump works, the same water heater.
I was checking the PCB , it looks OK. So, I was thinking that probable are the carbon brushes. I've changed them and it was working, I was lucky. Because was not easy to identify and to replace the brushes I want to share with you haw to do it.
What you need for this:
- a cross (+) screw
- a lamp; the brushes are placed in no accessible places so you may need some extra light
First o all you have to cut the power supply, cut water supply too.
Next thing to do is to remove the back cover (there are 5 cross screws), this will give some light inside of the washing machine and also you can easy manipulate the machine for next step.
Put the washing machine on its side , with the soapbox on the bottom, like in picture below.
It's important that the corner with PCB (red dot) to be on upper side; if there is still some water into the machine, at least it will not be drawn on PCB.
Now we have access on the bottom of the washing machine, there is no cover to remove or something like this.
Below is a picture where the motor is visible. In the picture below the brushes have already been removed. But we can see where they are located, and see that any of them is fixed by the motor with 2 screws (again cross screws). One location (upper brush) is very visible, but not the same we can tell about the 2nd one.
For a better visibility I have two other shots from the back of the motor (camera) was in the yellow circle position.
After you have removed the brushes replace them with the new ones. To be sure that I replace them with the proper brushes I've go with the old ones to the store, and clerk provide me exactly what I needed . As you notice in the last picture, it is obvious that the old ones have come to the end of lifetime.
