Jenn-Air Dishwasher Error Code 160° Rinse LED + Clean LED

The simultaneous illumination of the 160° Rinse LED and Clean LED on a Jenn-Air dishwasher signals a motor low current condition, detected specifically during the Field Service Test mode. This diagnostic state indicates that the wash motor is drawing less current than expected during operation, which points to an interruption or degradation in the motor circuit rather than an overload condition. Low current faults typically arise when the motor is not receiving a complete circuit, when internal motor windings have failed, or when connection points along the motor harness have corroded or loosened.

The wash motor in these dishwashers should measure between 3 and 4 ohms of resistance across its terminals when tested with a multimeter. A reading significantly outside this range, whether an open circuit or a value far below 3 ohms, confirms a motor winding failure. Resistance within spec but accompanied by the fault code shifts suspicion toward the wiring harness, connectors, or the control board output driving the motor circuit.

Diagnosis begins with a resistance check across the wash motor terminals to confirm whether the motor itself is within specification. If resistance checks out, the next step is verifying the motor actually runs during the Manual Function Test, which activates individual components directly and helps isolate whether the fault is in the motor, the wiring, or the control board. Loose or corroded connector pins at the motor plug are a common and often overlooked contributor to low current readings.
