I have a fairly new Frigidaire dishwasher that won't start. It worked fine two days ago but now when i go to start a cycle, the "Washing" light continually flashes. It's almost as if it thinks the door is continually open. I did have a fuse blow and it the dishwasher was in its power-on mode, but I cleared those lights and now it won't work. Any ideas before I spend $$$ on a new control module? Thanks...
