When operating door switch, the dishwasher would work intermittently. I removed the door inner liner and checked: my model had two switches side by side. One was obviously bad: the switch button was pushed in and would not spring out. The other looked OK. I ordered two switches on a Monday and Tuesday evening they arrived. I popped them in taking about 20 minutes total and back in business. The exploded views of parts shown on the Appliance Parts Pros site is a real help in identifying parts and part numbers.
