Fisher & Paykel Washer Dishwasher Oven Error Code 6

Error code 6 on Fisher & Paykel appliances indicates a motor controller fault. The motor controller is the electronic module responsible for regulating power delivery to the drive motor, controlling speed, direction, and torque. When this fault is triggered, the appliance's main control board has detected an abnormal condition within the motor controller circuit, which may include irregular voltage, unexpected current draw, or a failure in the communication between the controller and the motor itself.

The fault can stem from several sources. The motor controller board may have failed due to heat stress, power surges, or component aging. Wiring harness issues such as loose connectors, corroded terminals, or damaged insulation between the motor and controller can cause signal irregularities that trigger this code. The drive motor itself may be drawing excessive current due to a mechanical obstruction or internal winding failure, which the controller interprets as a fault condition.

Because the motor controller is a critical safety and functional component, the appliance will typically halt operation when this code appears. Diagnosing this fault requires inspecting the wiring harness for continuity and physical damage, checking for any obstructions in the motor's mechanical path, and testing the motor controller board for signs of burning, cracked solder joints, or component failure. In many cases, the motor controller board will need to be replaced if internal damage is confirmed.
