The problem with KitchenAid Dishwasher KUDS35FXSS1 was that upper and lower spray arms didn’t wash dishes at all. Our technician diagnosed an issue. His huge experience with Kitchenaid dishwashers repair allowed him to presume that the reason of the dishwasher’s wash motor low productivity is a failed chopper.
Disassembling an appliance confirmed the diagnosis. Replacing the chopper significantly improved dishwasher’s productivity. it works better than new now.
