Possible Causes
Worn rear drum bearings, Failed bearing seal allowing water ingress, Bent drum shaft (spider), Corroded bearing housing
How to Fix / Troubleshooting
Safety first: Unplug the appliance. Be aware that bearing replacement is a major repair.
- Confirm bearing noise: Spin the empty drum by hand. A rough, grinding sound or excessive play when lifting the drum up and down indicates bearing wear.
- Check for leaks: Look for rust streaks or water marks at the rear of the tub, suggesting seal failure.
- Assess repair scope: On many Blomberg combos, bearings are integrated into the outer tub. Replacement may require changing the entire rear tub half or complete tub assembly.
- Professional repair recommended: Due to the level of disassembly (removing drum, motor, and tub), bearing replacement is best handled by an experienced technician. Continuing to use the machine can lead to drum damage and leaks.
