All true - but what about the DW which trips the RCD when it is plugged in but not switched on? ... and don't forget that exactly the same happens when the DW is plugged into different sockets, on different circuits, via an extension cable. That sounds to me like a either a fault in the DW's flex/plug, or a N-E fault within the DW, coupled with it only having a SP switch - but, in either case, the problem would be 'with the DW'. What's wrong with my reasoning?
That's obviously a possibility (if the DW has SP switching, or has filter capacitors on the supply side of the switch) but, if that were the case, I would have expected that other appliances would probably do the same, at least sometimes.
Just replaced our 12 year old DW:
A lot more "unlucky" than me, it seems - at least I've never had to have more than one replacement for a brand new appliance.
As I would have had to clean a replacement I accepted the 4th and used a bit of kitchen towel and white spirit. All I need to do now is work out how to remove some of the useless plastic accessories.
