Fisher & Paykel Washer Error Code E7:02

E7:02 means the motor control module has detected a loss of one phase in the drive motor circuit. The washer motor requires three electrical phases to operate, and when one is missing or interrupted, the machine stops and displays this code. The fault can originate in the wiring harness, the connectors, the motor windings, or the motor control module itself.

Resetting the washer may temporarily clear the error code from the display, but the fault will return as soon as the machine attempts to run the motor if the underlying problem has not been fixed. The motor control module monitors phase continuity during operation, so the code will reappear until the wiring, connector, or component issue is properly resolved.

Repair costs depend on the root cause. If the fix involves reseating a connector or repairing a wire in the harness, the cost can be relatively low, generally in the range of $50 to $150 for a service call and labor. Replacing the motor can cost between $200 and $450 including parts and labor, while a motor control module replacement typically falls in the $250 to $500 range depending on parts availability and local labor rates.

A knowledgeable DIYer can begin by inspecting the motor harness and connectors for visible damage, corrosion, or loose connections. Resistance testing between the motor phases at the control module connector is the recommended first diagnostic step, with a target reading of 28 ohms plus or minus 1.95 ohms at 20 degrees Celsius. If the harness and connectors appear sound and readings are within spec, further diagnosis or component replacement may require a qualified technician.

The washer should not be operated while this fault code is active. Running the motor with a missing phase can cause additional stress on the motor windings and control module, potentially turning a simple wiring repair into a more costly component failure. Leave the machine unpowered until the fault is diagnosed and corrected.
