Blomberg Washing Machine: drum and belt issues
What is this symptom?
Experiencing issues with your Blomberg washing machine's drum and belt? If the drum fails to turn, spins improperly, or makes unusual noises, it may be due to a worn drive belt, motor problems, or unbalanced loads. Identifying the cause can help you implement effective solutions.
Important Tips for Blomberg Models
- Blomberg support specifically lists unbalanced load, overloading, drainage and door lock issues as spin-related causes and suggests professional help for motor or belt faults.

User Suggested Solutions
-
Inspect the drive belt for wear and tear. If damaged, replace it by loosening the tensioner and removing the old belt. Install the new belt by threading it around the motor and drum pulleys, ensuring it's properly seated.
-
Check the drum bearings by manually spinning the drum. If it feels rough or makes noise, remove the drum to replace the bearings. This involves taking off the front panel, disconnecting the drive belt, and unscrewing the drum assembly.
-
Examine the drum for any foreign objects that may be causing obstruction. Remove any visible items and ensure the drum can rotate freely.
