Bosch Serie 4 drum rotation
Hi all,
I'm hoping someone can provide some thoughts/suggestions on an issue we're having.
We bought a second hand Bosch Serie 4 washing machine. Recently we've noticed that the drum has a tight spot when rotating it by hand. This tight spot appears to change position each time we rotate the drum (I.e. 1st rotate, the drum will spin freely until it hits the tight spot at 3 o'clock position, rotate again and the tight spot is now at 1 o'clock, rotate again and it's at 7 o'clock).
When the drum hits the tight spot it doesn't feel/sound like it's grinding, and it doesn't suddenly stop. It is silent and slows the drum rotation quickly at that specific point. It feels like like there's a bit of rubber catching and slowing the rotation.
I haven't removed the back/top of the machine yet to take a look.
Does anyone have any suggestions as to what may be causing this and the potential solution?
Thank you

Bosch Serie 4 drum has a shifting tight spot when turned by hand
- The problem
- A second-hand Bosch Serie 4 washing machine developed a silent tight spot when the drum was rotated by hand. The resistance did not stay in one fixed position and seemed to move on each rotation. There was no grinding noise; the drum simply slowed sharply at one point, described as feeling like rubber catching.
- Likely cause
- The strongest suggestions were that the drum lip may be catching on the door seal, possibly because the drum lip is not perfectly circular, or that an item such as a sock may be trapped underneath the drum. The exact cause was not confirmed.
- What fixed it
- Recommended checks were to carefully inspect and feel whether the drum lip was catching the door seal, and to remove the belt so the drum could be turned separately from the motor to confirm whether the resistance was in the drum rather than the drive system. No completed repair was documented.
- Checks to try
- Carefully examine and feel whether the lip of the drum is catching on the door seal
- Remove the belt and turn the drum separately to confirm whether the issue is with the drum rather than the motor
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

Hi, It should be easy enough to check if the lip of the drum is catching on the door seal. Just carefully examine and feel. Maybe the lip of the drum isn't a perfect circle and has a pronounced bit.
Another possibility is something like a sock stuck underneath the drum.
Also, to be sure it's an issue with the drum, and not the motor, you would need to take the belt off and turn the drum separately.
