KitchenAid Dishwasher Error Code 4-4

Error code 4-4 on a KitchenAid dishwasher indicates a wash motor failure condition. The control detected a problem in the wash motor circuit, which could be a loose connection, an open motor winding, a blown motor fuse, or a failed motor drive circuit on the control board. The dishwasher halts the cycle when this fault is detected to prevent further damage.

No, you should not attempt to run the dishwasher while error 4-4 is active. The wash motor is not functioning correctly, meaning the dishwasher cannot properly circulate water. Running a cycle in this condition will not clean dishes and could cause additional stress on other components.

Resetting the dishwasher by disconnecting power for a few minutes may temporarily clear the display, but the code will return if the underlying problem in the wash motor circuit has not been fixed. A reset is a useful first step to confirm whether the fault is persistent, but it does not repair a failed motor, open fuse, or damaged wiring connection.

Some causes of error 4-4 are DIY-friendly, particularly reconnecting a loose harness connector. Before doing anything, unplug the dishwasher or disconnect power at the breaker. Use a meter to check continuity across all connections in the wash motor circuit, and inspect the motor fuse. Replacing the wash motor or control board typically requires more experience and may be better suited to a qualified technician.

Repair costs vary depending on the root cause. Reconnecting a loose wiring harness may cost little to nothing beyond a service call fee. Replacing the wash motor typically runs between $150 and $400 in parts and labor. A new control board can add another $100 to $350 or more depending on the model. Getting a diagnostic done first helps narrow the cost before committing to parts.
