Hi Our Bosche WFF2000 tripped our main RCD at the end of a wash (door lock had released) and now is permanently leaking live to earth. I have tried disconnecting the motor with no change so am guessing the issue is eleswhere. Whilst I'm normally happy to have a go at most things, this seems a little complex without the necessary equipment or going round unplugging everything using trial and error. Is anyone aware of anything obvious (and relatively simple with just a multi-meter) to check? My feeling is that is is getting on a bit and needs replacing.
