Fisher & Paykel Washer Error Code 55

Error code 55 indicates a Phase 3 to 6 System Step Fail caused by a Rotor Position Sensor fault. The Rotor Position Sensor monitors the motor's rotational position and provides feedback to the motor controller. When this sensor or its wiring fails, the motor cannot operate correctly and the washer stops to prevent damage.

No, you should not continue running the washer with error code 55 active. The fault indicates the motor control system cannot accurately track rotor position, which means the motor cannot run correctly. Continued use could cause further damage to the motor or control board.

A reset may clear the displayed code temporarily, but if the underlying fault with the Rotor Position Sensor or its wiring has not been corrected, the error will return during the next wash cycle. A proper repair requires diagnosing and resolving the wiring or sensor issue before the fault is truly resolved.

A knowledgeable DIYer can start by inspecting the motor and Rotor Position Sensor wiring for loose connectors, corrosion, or visible damage. However, properly confirming whether the RPS itself has failed requires the Fisher & Paykel RPS Tester tool, which is typically available only to technicians. If wiring checks out and the sensor needs testing or replacement, professional service is recommended.

Repair costs depend on the root cause. If only a wiring connector needs reseating or repair, costs may be relatively low, generally in the range of $75 to $150 for a service call. A Rotor Position Sensor replacement typically adds $50 to $150 in parts. Motor control board replacement is the most expensive scenario, often ranging from $200 to $400 or more including labor.
