Beko washing machine drum whirring after brush replacement

The problem

After replacing the motor brushes on a Beko washing machine, the drum turned briefly with a whirring noise, then stopped. It then made a repeated attempt to start every few seconds without moving. Turning the drum by hand also produced an unusual whirring sound.

Likely cause

The accepted reply says the whirring may simply be new brushes bedding in, provided they are fitted correctly and the full brush face is contacting the commutator. Because the motor ran briefly and then failed, a poor connection on the motor connector block or elsewhere was also suggested. A fault with the main PCB was mentioned as another possibility, but not confirmed.

What fixed it

Check that the new brushes are fitted properly and that the full brush surface is running on the commutator. Check for a poor connection on the motor connector block or elsewhere. The reply also questioned whether the original brushes were definitely the cause of the fault. If the problem remains, further diagnosis should be carried out by a suitably qualified appliance engineer rather than guessing at expensive parts.

Checks to try

• Confirmed the drum spun for a second before stopping
• Noted repeated attempts to start every 5 seconds
• Turned the drum by hand and heard unusual whirring
• Advised to check brush fitment and contact with the commutator
• Advised to check the motor connector block and other connections

Parts or tools mentioned

• Motor brushes
• Motor connector block
