Jenn-Air Dishwasher Error Code 4-4

Code 4-4 means the control board has detected a failure in the wash motor circuit. This could be a loose or open wiring connection, a failed wash motor with open windings, or a blown motor fuse on the control board. The dishwasher will not complete a wash cycle while this code is active because the motor that circulates water is not functioning properly.

No. With code 4-4 active, the wash motor circuit has failed and the dishwasher cannot circulate water through the spray arms. Running a cycle will not clean dishes and the machine may not complete the cycle at all. Do not attempt to run the dishwasher until the wash motor circuit fault has been diagnosed and repaired.

Code 4-4 will not resolve on its own because it indicates a real electrical fault in the wash motor circuit, not a temporary sensor glitch. Restoring power after an outage may briefly clear the display, but the code will return as soon as the control board checks the circuit again and finds the same open condition. The underlying cause must be physically corrected before the code will stay cleared.

Start by unplugging the dishwasher or shutting off power at the breaker. Use a multimeter to check continuity at every connector in the wash motor circuit, including the motor terminals themselves and the motor fuse on the control board, as described in the Fuse Service and Diagnostic Checks procedure in your service manual. If a connector is loose, reseat it and retest. If the motor shows no continuity across its windings, the motor needs to be replaced. If the fuse on the control board is open, the board will need fuse replacement or full board replacement. A repair technician is advisable if you are not comfortable using a multimeter on live appliance components.

If the fix is a loose connector, there is no parts cost, only your time. A replacement wash motor for a Jenn-Air dishwasher typically runs between $80 and $200 for the part, depending on the model. A service call with labor can add $100 to $200 or more on top of parts. If the control board needs fuse replacement or full replacement, board costs can range from $150 to $350. Checking the connectors and motor yourself before calling a technician can determine whether you are looking at a no-cost fix or a larger repair.
