Jenn-Air Dishwasher Error Code 8-2

Code 8-2 means the control board has detected an electrical problem in the drain motor circuit. The board is reading either a loose or open connection in the wiring to the drain motor, or an open winding inside the drain motor itself. Either condition prevents the motor from receiving current, so the dishwasher cannot drain.

Running the dishwasher with code 8-2 active is not advisable. Because the drain motor circuit has an electrical fault, the dishwasher will not be able to pump water out of the tub, and cycles will not complete normally. Continuing to attempt cycles may leave standing water in the tub and could cause the control board to log additional faults. Resolve the drain motor circuit issue before resuming use.

Code 8-2 covers both possibilities. The fault points to the drain motor circuit as a whole, meaning either the drain motor's internal winding has failed open or a connection somewhere in the wiring between the control board and the motor has become loose or broken. Testing resistance at the motor windings and checking continuity through each connector in the circuit will determine which component is actually at fault before any parts are purchased.

Start by unplugging the dishwasher or shutting off its circuit breaker. Then locate the drain motor and use a multimeter to test the resistance of the motor windings and check continuity through every connector in the drain motor circuit. If a connector is loose, reseat it. If a wire is broken or corroded, repair or replace it. If the drain motor winding tests open with no continuity, the drain motor itself needs to be replaced. If you are not comfortable using a multimeter or accessing internal wiring, a qualified appliance technician can complete this diagnosis quickly.

If the fix is a reseated connector or a repaired wire, parts cost is minimal and the repair is a DIY job for someone comfortable with basic electrical testing. If the drain motor needs replacement, the part typically costs between $40 and $120 depending on the model, and a service technician will add a diagnostic fee plus labor, often bringing the total to $150 to $300. Getting the exact drain motor part number from the model label inside your dishwasher door will help you source the correct part.
