Miele washing machine - tripping the electricity (RCD)

[taylor]

Hi I have a Miele W5741 washing machine which is three years old.
The other day it tripped the electricity (RCD)
I found that I could it would trip the RCD every time regardless of what program I used.

After a few trials I have found the following: if I use the machine and select cold water (no heating of water) then it does not trip the electricity (RCD).

So my conclusion is that it is the heater that is causing the washer to trip the electricity! What do you think?
I opened up the front to locate the heater. However I don’t see how I can remove the heater as I see no screws!
I have attached a pic so you can see the front/heater.

Any suggestions to remove the heater?

Gently pull out the NTC unit from the middle then ease the rubber seal out with a screwdriver take care as the new element may come with a different seal.
