Jenn-Air Dishwasher Error Code Super Scrub LED + Clean LED

The Super Scrub LED and Clean LED illuminating together on a Jenn-Air dishwasher indicates a motor high current condition detected during the Field Service Test mode. This fault points directly to the wash motor circuit drawing more amperage than the control expects under normal operating conditions. When current draw exceeds the acceptable threshold, the control board flags this combination of LEDs to alert a technician that the motor or its associated wiring is operating outside of normal parameters.

The wash motor is the core component responsible for circulating water through the spray arms during a wash cycle. A properly functioning motor should measure between 3 and 4 ohms of resistance across its windings. A reading significantly below this range suggests a shorted winding, which would cause excessive current draw. A reading well above this range, or an open circuit reading, would indicate a different motor fault. Beyond the motor itself, the wiring harness and connectors feeding the motor should be inspected for corrosion, damaged insulation, or loose terminals that could create abnormal resistance in the circuit.

Mechanical binding is another leading cause of this fault. If the wash pump impeller is jammed by debris such as broken glass, food particles, or a foreign object, the motor must work harder to overcome the resistance, resulting in elevated current draw. Inspecting the pump housing and impeller for obstructions is a critical diagnostic step before condemning the motor. If the motor windings test within the 3 to 4 ohm specification and no binding is found, attention should shift to the control board, which may be misreading current or failing to regulate motor output correctly.
