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.
