Hotpoint WML520 drum seized and will not turn

The problem

A Hotpoint WML520 Aquarius stopped mid-cycle after an odd noise. Afterwards the drum would not turn. The rear drum pulley could only be moved by about 1 to 2 mm, and with the belt fitted the motor and belt appeared to try to drive the drum but it remained stuck.

Likely cause

Most strongly supported diagnosis is a seized drum assembly rather than a simple belt issue. The accepted reply says this could be due to seized drum bearings, especially if the machine had been noisy for some time, or something jammed inside the drum/tub area. The exact cause was not confirmed.

What fixed it

Recommended action was to remove the drive belt to confirm whether the seizure is in the motor or the drum. If the drum is still stiff with the belt removed, the fault is likely within the drum assembly. The exact repair was not confirmed in the discussion. Further diagnosis should be carried out by a suitably qualified appliance engineer.
