Maytag Washer Error Code d4/F01

The d4/F01 code means the control board has detected a fault in the motor relay control circuit. The board cannot determine whether the motor relay is stuck on, whether the relay drive circuit is shorted, or whether the relay feedback circuit has failed. As a safety precaution, all wash cycles and the price display are disabled until the fault is manually cleared.

No. The machine disables wash cycles specifically because it cannot confirm the drive motor is being controlled safely. A relay stuck in the on position could cause the motor to run uncontrolled, which is a potential safety hazard. The washer should remain out of service until the fault is diagnosed and repaired.

Repair costs depend on which component has failed. If the problem is a loose or damaged wiring connection, the cost is minimal. A replacement main control board, which is the most common fix, typically ranges from $150 to $350 or more depending on the specific model, plus labor if a technician performs the work. Diagnosing the exact failure point first will help avoid unnecessary parts replacement.

Some steps are DIY-friendly, such as inspecting the wiring harness connections at the control board and drive motor for looseness, corrosion, or visible damage. However, if the fault is traced to the main control board itself, replacing that component requires comfort working with electrical parts and disconnecting power safely. If you are unsure, a qualified appliance technician is recommended.

The code description states it must be manually cleared, meaning a simple power cycle may not permanently resolve it. If the underlying fault in the motor relay circuit still exists after a reset, the code will return as soon as the control performs its self-check. The root cause must be identified and repaired for the error to stay cleared.
