My tumbledryer sometimes fails to start, the display shows E50. The drum is very hard to turn even when empty. I've opened it, but cannot find anything wrong, the both bearig wheels in front of the drum is running ok, but it looks like there is rather heavy friction between the drum and the front of the dryer. Is there some adjutment or need for cleaning or what?

E50 is a motor revolution issue.could be related to a tight drum but they are hard to rotate by hand even when new.possible parts that cause this fault code assuming the drum isn't over tight are motor.capacitor attached to the motor.control pcb triac fault or belt tensioner not rotating freely on motor mounting pin.not easy to diagnose some of these without test equipment.
