Cakeboy, did you have any issues like this ?
Thanks again
I agree with Cakey that it is far better to be safe than sorry. Please unplug you machine from the mains before doing ANY testing. You can follow the instructions in the linked thread to test the resistance of the elements and also test the resistance to earth from either side of the elements to confirm that this is the cause of the RCD trip.
If you are not comfortable checking the above you could take the following steps instead:
1. Unplug the machine from the mains.
2. Disconnect the power to the heater by removing both spade connectors.
3. Plug the machine in and confirm that the RCD no longer trips on position 2.
If you find the RCD trips with the heater connected and does not trip with it disconnected then you know the heater is the problem.
