This dishwasher is 2 years old. I start the cycle and it fills with water normally. When it starts to wash, there is a clicking sound behind the control buttons and it makes a buzzing sound. It does this 3 times. It then cancels the cycle and drains out and goes off. This dishwasher has always had "phantom" lights on the control panel. We had tried unsuccessfully several times to have this fixed through Kitchenaid or Lowe's. I don't know if we should start with the wash pump or the control panel. Any ideas are appreciated. Thanks!
