My Kitchenaid dishwasher works but it is making noise. It used to be so quiet I wondered if it was even on. Now, it periodically makes a loud humming noise. I don't want to purchase a new pump and motor assembly if I'm not sure if that's the actual problem. It could also be the drain pump, the circulation pump, the drain impeller or the wash impeller. How can determine which one it is?
