Dishwasher tripping electrics?

Hi all

I have a diplomat dishwasher (model no ADP8332)

I have given up trying to use it and resorted to the old fashioned method :-)

Problem is I use the dishwasher, works fine through the entire cycle but if I try to use it a second time it trips all the electrics.

I'm thinking some sort of leak, but i'm just guessing so any suggestions would be welcome.
