Do-It-Yourself Story

I removed the door panel to assess internal components, My first thought was the door switch. I checked the switch and it was operating properly. I then moved to control module. power was to module but nothing coming out of module. The fuse integrated in the module was patent but I noticed a dark area on the circuit board concentrated around the power inlet location. I removed the module and behind the dark area was melted. new module and dishwasher works like new.
