Hotpoint WM22 drum not turning though machine still fills and drains

The problem

Hotpoint WM22 washing machine drum stopped turning after long service. Other functions were reported as normal, including filling and draining. The belt was intact, power was present, electrical connections appeared sound, and the motor brushes and continuity across the 7 motor pins were reported as checked.

Likely cause

The strongest diagnosis in the discussion was a motor brush problem, as sticking or worn carbon brushes were described as the number one suspect on Hotpoint machines with a non-running motor. As the original poster said the brushes tested OK, the next likely cause suggested was a fault on the main PCB/module or a motor plug/wiring harness connection fault. Exact cause was not confirmed.

What fixed it

Recommended actions were to recheck the motor plug and wiring harness for connection faults. If no connection issue could be found and the motor tested OK, the advice was that the PCB/module could be at fault, but this could not be meaningfully tested in the discussion other than trying a replacement or having the board professionally tested. No confirmed repair was posted.
