Hi Kenny,
You need to remove the calc elemant in front of the 2 steam buttons then using a small screwdriver prise the 2 steam buttons out, you can then see the top screw with the security ctr pin. you can then release the top handle there is a clip just under the black heat selector lever. The electronics are all encapsulated. The most common reason for the house earth leakage to trip is the main heaters go porous or if really bad will trip the ring current breaker.
