Older Whirlpool-built Kenmore dishwashers from the 2000s ran on a mechanical rotary dial with no digital problem-light system — a technician diagnoses these by direct testing of the heating circuit, drain path, and door latch rather than reading a display.

A Kenmore dishwasher that stalls partway through an UltraWash or UltraWash Plus cycle is usually reacting to a specific sensor or flow problem, not failing at random.
