Recently had that on my bosch washer dryer, a underwire bra had got sucked into a pipe at the front of the drum and jammed the whole thing, repair was well over £500 so had a new one instead, glad I got extended warranty, then had the problem of explaining where the bra came from as wasn't the gf's ha ha!!
I do know from what the man said that the overheat stat had popped, and it burnt out a board at the front.
