My Kitchenaid dishwasher will not start at all. I have tried turning off power at the electrical panel, leaving it off for a couple of hours, turning it back on. This didn't help. The only lights that come on are the normal light and energy saver dry. The rest don't come on at all. I tried to reset it but the buttons don't seem to be working. How can I repair my dishwasher ? Is this something I can repair myself ?
