What 8-2 means on a Jenn-Air dishwasher

Error code 8-2 on a Jenn-Air dishwasher indicates the control board has detected an electrical problem in the drain motor circuit. Specifically, the board is seeing either a loose or open connection somewhere in the wiring between the control board and the drain motor, or an open winding inside the drain motor itself. An open winding means the internal coil of the motor has broken continuity, preventing current from flowing and the motor from operating. Diagnosis requires resistance testing of both the motor windings and every connection in the circuit after disconnecting power.

For homeowners, the drain motor is the component responsible for pumping water out of the tub at the end of each cycle. When the control board sends a signal to drain and gets no valid electrical response from that motor circuit, it triggers code 8-2 and stops the cycle. This could mean a wire connector has vibrated loose over time, a wire has corroded or broken, or the drain motor itself has internally failed. The dishwasher cannot complete a drain cycle until the fault is resolved, so standing water in the tub is a likely symptom alongside this code.

Common causes of 8-2

  1. 01

    Open drain motor winding

    Part replacement

    The internal coil winding inside the drain motor has broken, creating an open circuit. When tested with a multimeter, the motor will show no continuity or an out-of-range resistance reading, confirming the motor needs replacement.

  2. 02

    Loose or disconnected wiring harness connector

    Wiring / connection

    The wire harness connector at the drain motor or along the drain motor circuit has worked loose from vibration during normal use. This interrupts the electrical path to the motor and triggers the 8-2 fault even if the motor itself is functional.

  3. 03

    Broken or corroded wire in the drain motor circuit

    Part replacement

    A wire in the drain motor circuit has cracked, corroded at a terminal, or been pinched, creating an open in the circuit. Visual inspection and continuity testing of the full harness run from the control board to the drain motor will identify the break.

  4. 04

    Damaged drain motor terminal or connection point

    Part replacement

    The individual terminals on the drain motor connector or at the control board connection point have corroded, burned, or deformed, preventing solid electrical contact. Cleaning or replacing the affected terminals or connector housing can restore the circuit.

Frequently asked questions about 8-2

What does error code 8-2 mean on a Jenn-Air dishwasher?
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.
How do I fix error code 8-2 on a Jenn-Air dishwasher?
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.
Can I still use my Jenn-Air dishwasher with a code 8-2 active?
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.
How much does it cost to fix a Jenn-Air dishwasher error code 8-2?
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.
Is error code 8-2 on a Jenn-Air dishwasher a drain motor or a wiring problem?
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.
