Kitchenaid dishwasher one light working

Hello, I have a kitchenaid dishwasher that stopped working after the last wash. Only the "Normal" light of the cycle type will light up and the washer will not come on at all. I replaced my old kitchenaid with this Craiglist one, but it is in extremely good condition. I have only used it 4 times when this happened. I checked the thermal fuse and door latch micro switch and they are both working. I took the control panel off my old one and it is a little different, but I could physically plug it in. I do not know what to do next and any help would be greatly appreciated.
