Kitchenaid resets?

I had a problem with my 2 1/2 year old dishwasher, it would not run a full cycle, and had a repair person come out and said I needed to replace the electronic control. I ordered the control through your company and carefully replaced took out the old one and replaced it. I pressed the sani rinse and heat dry buttons in sequence to reset the machine and pressed start. The machine begins to run for about three minutes, then stops, and the cancel light comes on. What else do I need to do?
