My KitchenAid dishwasher, KUDC10FXSS3, is making noise. It did it once before when the chopper motor was jammed with a piece of mussel shell. Cleaned it out again, but still making noise. Last time I had the page with the diagnostic procedures, wiring diagram, and fault codes, but I can't find it. Can you help me get a new diagnostic guide, or tell me how to enter and exit diagnostic mode, and read the fault codes.
