Suddenly the other night the dishwasher turns itself on... I check and it's on a Pots and Pans cycle (which I never use). I push cancel. Nothing happens. I open the door and close. It goes back to Pots and Pans cycle. I try to push cancel and the lock light comes on. I disconnect the power hoping it will reset, but after 24 hours it still goes back to the same cycle where it starts, loads water and that's it. Help!
