Wash motor fault

Listen at cycle start — humming means the motor is energized but cannot turn (seized or jammed)
Check the motor capacitor with a multimeter — a failed capacitor prevents the motor from starting
Inspect the sump for food debris or broken glass jamming the impeller
Test the control board relay — listen for a click when the wash phase begins
Pro Diagnostic Tip
On KitchenAid KDTM models, food particles can jam the diverter disc and impeller. Before condemning the motor, disassemble and clean the sump. Broken glass from a cracked dish or wine glass is the most common cause of sudden motor seizure.
