AEG washer dryer bangs loudly only at high spin

The problem

An AEG washer dryer was reported to make a very loud banging noise, described as something bouncing around in the mechanism. The noise could not be reproduced by turning the drum by hand and only occurred at the fastest spin.

Likely cause

The accepted reply says the sound suggests something is very loose. The most strongly supported possibilities mentioned were a loose component, the motor assembly, or a loose drum pulley. Bearings were considered by the owner from a guide, but the discussion does not confirm bearing failure.

What fixed it

Recommended action was to disconnect the appliance from the electricity, then check for anything obviously loose by shaking components carefully. If nothing obvious was found, the accepted advice was to remove the belt and listen to the motor spinning without the drum load, and to check whether the drum pulley where the belt fits was loose. The exact repair carried out was not confirmed in the thread.

Checks to try

• Noise only happened at highest spin
• Drum was spun by hand and the noise was not reproduced
• Check for loose parts with the appliance disconnected
• Remove belt and assess motor separately from drum
• Check whether the drum pulley is loose
