We had a power outage yesterday and now when I try to use the dishwasher, the control panel won't allow itself to start the wash cycle on normal. Selecting anything but light or rinse won't respond, I can't get it to start. At one point, I was able to start the rinse cycle but as of now, I can't get the dish washer to run at all, it's like the front control panel has stopped functioning. What part is likely to have failed on this dishwasher so that I can repair/replace it?
