Hi

The most common parts to causes this kind of fault is either the washer heater or the motor.

Do you have a megger or insualtion meter you can test the washer with?

If so then test the insualtion of the washer and if very low disconnect the washer heater at the back and see if this clears it. If so then its the heater thats faulty. If thats fine then do the same to the motor and see what you find.

But on these the most common parts to cause this is the wash motor or the heater so check them both and see what you find.

hi there. the machine has done this for weeks and does heat the water ok when it is started ok. only every so often will it trip the rcd

Ive had the wash heaters do this so as the heater gets hot the insulation weakens in there so it leaks to earth and trips the electrics out.

Motors dont usually work for periods and then start tripping so i this case i dont think the motor is the cause unless something it leaking onto.

Have you checked for water leaks leaking on to the motor wiring.

As these washers do like to leak from the rear bearing seal and runs down the back of the drum onto the motor wiring.
Have a look at the wiring and see if theres signs of water leaking on there. It may be only a small leak but the water drops run down the wiring to the motor block and can cause this.
So if it has signs of water marks try and reroute the wiring so it loops down and back up so that way the water cannot travel back up if you know what i mean.

hi there, thanks for all your info and time. i disconnected the heater and motor and the machine still trips the rcd. i also checked for any water leaks. could it be an earth leak on the board.

Ok to be honest a control board doesnt cause a tripping fault as its not earthed.

If its not the motor or the control board then try and replace the plug top. As in the past ive had the moulded plug top fail and short to earth. So cut the moulded plug off and replace it and see how that goes.

If its still tripping then you need to go through all the wiring in there and check for any shafted wires rubbing on the cabinet.
If the wires are fine as well then you will need to get a megger to test the insualtion of the machine and find the earth fault that way.

But just try the plug top first and see how that goes.
