Miele W1 PowerWash&TwinDos sparking/noise from drum at high speed

The problem

The washing machine made a noise only during the fast spin stage, and the original report mentioned visible sparks. After dismantling, the poster found metal discolouration consistent with friction and said one corner of the drum had become sharp. With the belt removed, turning the drum by hand still produced the noise, mainly when turned clockwise.

Likely cause

Most strongly supported diagnosis is mechanical contact inside the drum area rather than a motor fault, because the noise remained with the belt removed. Forum replies suggested the drum may be catching on something metal, with bearing or drum spider problems also considered, but the exact fault was not confirmed.

What fixed it

The accepted advice was to disconnect the motor belt and run the motor separately to distinguish motor noise from drum/internal mechanical noise. Based on the follow-up findings, further strip-down investigation would be needed to confirm whether the fault was with the drum, bearing or spider. The poster then decided to scrap the machine rather than continue repair.

Checks to try

• Observed sparks during fast spin
• Machine dismantled and metal discolouration from friction noted
• Sharp area/corner on the drum reported
• Drive belt removed
• Drum turned by hand with belt off
• Noise reported only when drum turned clockwise
