Fisher & Paykel Washer Error Code 134

Error code 134 on a Fisher & Paykel washer indicates that two separate fault conditions occurred simultaneously during motor operation: a single current trip (fault 130) and a rotor position sensor error (fault 132). The motor controller detected excessive current draw through the motor windings at the same moment it lost reliable feedback from the rotor position sensor (RPS). This combination fault is classified as a Phase 4 event, meaning it occurred during a specific phase of the motor control cycle. Because both faults are triggered together, the motor controller cannot determine whether the overcurrent condition caused the RPS signal to fail or whether a failing RPS caused the motor to draw excessive current.

The RPS is responsible for providing the motor controller with real-time information about rotor position so that current can be delivered to the correct stator windings at the correct time. When this signal is corrupted or absent, the controller may energize the wrong windings, leading to a stall condition or uncontrolled current spike. Conversely, a mechanical obstruction or winding fault can cause the rotor to stop abruptly, producing both an overcurrent event and an RPS dropout simultaneously.

Diagnosing fault 134 requires following the service procedures outlined for both fault 130 and fault 132 independently. Technicians should inspect the RPS wiring harness and connector integrity, measure motor winding resistance for shorts or opens, check the motor controller board for signs of heat damage or failed components, and verify that no mechanical obstruction is present in the drum or drive system. Resolving the root cause typically requires isolating whether the electrical or mechanical side initiated the dual fault condition.
