Have one of these that I’ve been to twice in the past.
Both times belt off. First time just put it back tested it for play, spin with load etc all ok.
2nd call noticed a yellow transit packing (pushed right in at the front) was falling back and catching the pulley on spin.
End of it I thought and that was b4 christmas.
She’s just called back and says its benn doing it again but she has now got fed up of putting the belt back on.
No noise reported or unusual spin, belt is ok, but it keeps being thrown off.
Don’t know anything else about these machines other than what I’ve read in posts, is this a fault that anyone else has encountered.
