Our 7 year old Bosch dishwasher stopped near the end of it's programme having blown the plug fuse and tripped the domestic circuit breaker. I replaced the fuse and the machine worked ok again but at some stage the circuit breaker tripped again but the fuse in the plug did not blow. Does any one have any ideas as to what could be causing this fault? Now running for the 3rd time with fingers crossed that it doesn't happen again, but not much hope of that!
