Washing machine is tripping RCD

[Abhi]

I have WD440 washing machine (Hotpoint), recently it started tripping the mains RCD.
I searched a lot online and tried disconnecting the pink wire which is connected to the heater.
I have tested the continuity of the heating element which is fine and is not borken.
It works fine and doesn't trip mains RCD anymore, except the drying part of the washing machine is not working.
Any help for troubleshooting and fixing the dryer would be greatly appreciated.

Thanks in advance!

Sounds like there is a breakdown of the heating element insulation which allows some current to flow to earth thus tripping the RCD. You might be able to confirm this if you have a good multimeter, a resistance to earth of 8 kilo-ohms or less will allow 30mA which is enough to trip the RCD. Replacing the element should fix it.

Thanks, I will replace heater element and see if everything works fine !

Yeah! It worked, heater element got rusted which was the cause of short circuit.
Thanks for the help
