Fisher & Paykel Washer Error Code 192

Error code 192 on a Fisher & Paykel washer indicates a Motor PWM Reset Pin Connect Fault. Specifically, the Motor Controller module has detected an open circuit between pins 30 and 31, which correspond to Phase 4 to 5 of the motor control circuit. The PWM (Pulse Width Modulation) reset pin is a critical communication and control point within the motor controller circuitry. When this connection is open or interrupted, the controller loses the ability to properly initialize and drive the motor, resulting in a complete motor shutdown.

The open circuit condition between pins 30 and 31 can originate from a failed internal component within the Motor Controller module itself, a broken or corroded connector at the relevant harness pins, or damaged wiring in the section of the wiring harness that connects those specific pins. Because the fault is detected internally by the Motor Controller, the controller's own sensing circuitry may also be at fault if the wiring and connector integrity check out as normal.

Since the motor cannot operate while this fault is active, the washer will be unable to complete any cycle that requires drum rotation. The primary diagnostic direction given for this fault is direct replacement of the Motor Controller module, as the fault is typically rooted in the controller itself rather than in upstream components. Before replacement, technicians should inspect the connector at pins 30 and 31 for corrosion, bent pins, or loose seating, as a poor connection at this point could produce the same open circuit reading.
