Miele washing machine - tripping the electricity (RCD) Answered

Hi I have a Miele W5741 washing machine which is three years old.
The other day it tripped the electricity (RCD)
I found that 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.

The heater is mounted using spring washers for safety reasons and to make you order a technician for the fix.
You can measure the resistance between the heater supply contacts and the metal ground around to confirm it is indeed faulty.
There should be little resistance between th contacts itself but nothing at all when you measure one of the contacts to the metal ground.
In your images you can see the spring washers on the pins.
It is not just a pain to get them off without the right tool but also to get replacement heaters that use this system AND supply new spring washers (or whatever the right name for them is).
Since there is not screws it is also really difficult to get the new one in without the tools to get the right pressure on the seals.
If you want to fix it yourself check if the heater itself is held by the washers, if so then you can replace it with a model that uses normal nuts to fasten the thing - just make sure the distance between holes, shape and power consumption are similar, brand name and so does not matter.

Yep. Sounds like a faulty isolation in the heater.

Nothing showing up here.

Sorry, no idea if / how it is possible for you to change the heater. Might be a job for a professional.
