Question about Dishwashers
Hello. Sometimes the cup will just get a build up of mineral or detergent on it that will cause it to become inoperable. If the cup door is hard to close or does not release easily, then a good cleaning may be all that is needed to get it working properly again. The best way to do the cleaning is to heat a cup of water up to very hot [close to boiling] and use a small brush like a toothbrush to clean all of the soap residue out of it. Rinse it a few times until the residue is gone.
Another cause could be the wax motor switch. On newer dishwasher they have a wax motor in which the wax is heated. This pushes a piston out which mechanically opens the door. The Timer activates the heat to the wax motor. Next is the bi-metal switch. These also are activated by the timer. These bi-metal switches will move or deform when electric which cause a bit of heat, is applied.
ALL of that said, another way around this door issue is to switch over to a dishwasher tab such as cascade which you literally toss in before closing the door. Joe
