Possible Causes

Worn rear drum bearings, Failed bearing seal allowing water ingress, Damaged drum shaft (spider), Corroded bearing housing

How to Fix / Troubleshooting

Safety first: Unplug the appliance. Sharp metal edges inside the cabinet can cause injury; wear gloves.

  • 1. Confirm bearing noise: Spin the drum by hand with the machine off. A rough, growling sound or side-to-side play indicates bearing wear.
  • 2. Check for leaks at rear: Look for rust streaks or water marks around the rear of the tub.
  • 3. Plan repair: Bearing replacement on Bosch washer-dryers usually requires tub removal and often replacement of the entire rear half of the tub or a bearing kit, depending on design.
  • 4. Professional recommendation: Due to the complexity and need for special tools, bearing replacement is best handled by an experienced technician.
