Customer Questions and Answers for Dishwasher Door Latch/Handle by Whirlpool

Peter, without a model and serial number, it'll be a bit difficult to advise you properly. There are several "revised" door strikes and latches over the years. You will need to partially remove the dishwasher to access the top tub support frame and replace the strike. There are several other "general" checks to make as well. Make sure the door and back wall of the tub are not "bowed" in or out. check and make sure the racks are back and as deep as possible, so the ends of the tracks are behind the door opening ridge. The dishwasher is properly leveled and installed to the cabinet, so the tub and door align and seal properly. Yes, excessively hot water (170 dgrs +) can cause the dishwasher door to open from the pressure produced in the tub. Make sure the initial fill water temperature is 120 to 130 dgrs.F. The sani cycle rinse should increase the water temperature to 150 dgrs. and hold it there for a pre set amount of time.
