Hi
I've got a Bosch WFVC6450UC/25 washer where the drum seems to have abruptly started wobbling when spinning and making a banging noise.

You can see a video of it here: https://streamable.com/d1j0dm

Any ideas on the cause? It moves off-center by maybe about an inch once per revolution always at the same point in the revolution.

Does anyone have a copy of the service manual for this model by the way?

Thanks
