Pulled the unit out of cabinet, had to disconnect power because power cord was too short. Flipped it over on it's side. The pump was easy to replace, pop off the hose clamp, take off two wires and twist it off. New one twists on easily. Reconnect wires and hose. Re-connect power and push it back in. Ran an empty load with CLR to de-scum the unit and leak check. The old pump had a hard piece of debris in it that killed the impeller.
