Do-It-Yourself Story

Turned off the circuit breaker, removed the inside racks, removed the lower front kick/trim plate, disconnected the electrical line, lowered the front adjustable feet, pulled the dishwasher out from underneath the counter far enough to remove the metal plate on the left side, reached inside the dishwaser and twisted the "brake cover" counterclockwise to remove it, then disconnected both sets of wires from the "assembly case sensor", disconnected the rubber drain hose, then twisted and pulled the "assembly case sensor" free from the "brake case assembly", ordered and received a new "assembly case sensor" from Appliance Parts Pros to replace the failed one and reversed the above process to reassemble. Dishwasher works perfectly now!
