Hi,
I have a Bosch washing machine that is 4.5 years old and has started tripping the RCD as soon as the motor starts.
With the earth spade disconnected from the motor then the RCD doesn't trip and the motor works.
I spoke to a local repairer and he advised that motors can develop some earth leakage over time and also that our old RCD could be over sensitive. I've checked and cleaned the brushes and commutator etc and they are fine.
He advised that leaving the earth spade disconnected with some electrical tape to insulate is an acceptable permanent solution so long as the resistance between live and earth on the motor is not less than 0.5 Mega Ohms.
I checked and the lowest resistance I could get was 0.7 mega ohms and that went to infinite with the brushes removed.
I just wanted to get a second opinion on here if this is an acceptable permanent solution.
After all, the rest of the washing machine is fully earthed and if there is a short circuit in the motor then it will simply blow the fuse right.
Opinions please?
