Had my head in a Miele dishwasher which is suffering an earth fault (10K
resistance live to earth, trips the RCD straightaway, was previously
emitting white smoke). Looking at the wiring diagram, my prime suspect is
the interference suppressor or failing that the heater relay.
(can't actually get at them to test)
I managed to find a parts list for a similar model on the net, so rang up
Miele with the part numbers in hand for a quote...
Relay 51.52 inc VAT
Next day postage 15.60
Ouch! I think I'll be buying from eBay or generics, for about a fiver each...
