have the same problem
there are 6 screws located to the top end and side to the door remove these and also the 2 screws holding the door catch.
the front panel will push out, there you will see 2 wires attached to a micro switch use a flat head screwdriver to prise the lever back
am trying to locate a new microswitch as I think this is the cause of the problem remember to unplug the dishwasher from the electricity supply first
