Servis M3022CW tripping electric

[systemtek]

This fault didnt start as this. Started as the washer would over fill to the point of over flowing (tried a few times kept doing it) so i checked the presure switch etc and all looked ok, so i tried it again and it was working ok, great its fixed i thought.

We left it a few hours then put a load of washing in as soon as we switched it on tripped the electric to our house, i checked the washer could not see any obvious reason why, all looked dry and no bad connections etc. So tried again same thing as soon as you pull the dial out after selecting your wash it trips the electric.

Any ideas as to why ? I not a washer enginner, but do work in electronics.

Thanks

Check the heater. Most likely suspect.



Unplug your appliance before working on it.

Afraid you'll have to take the back off and have a hunt for it. Somewhere near the bottom of the rear is the best hint I can give you.
You'll need to meter it for continuity as well as short to earth. Or, disconnet the heater wires, tape them up and try switching on.
Best bet is to use a megger and test for insulation, disconnect heater, test again. If readings are correct after disconnection then the heater is the problem.
