Have contacted 7 Accredited Miele service providers - 6 not willing to travel to my location - 7th didnt make contact as arranged - I wont be attempting any electrical work but keen to have a look and see if any foreign object (aka rodent, roach) is causing unit to "short" soon after starting up washer which then trips safety switch in the power box outside. I have taken apart front door completely and replaced but not sure how best to take back off unit. Any clues greatly appreciated.

You can't take the back off.
It's probably the element.
If you tip the machine on it's side & remove the base(4 screws) you'll see the element with 2 thick cables. Pull the cables off & insulate them.
Re-fit the base & try the machine again. If it doesn't now trip, then you'll know it's a faulty element.
They cost about £150.
