Fisher & Paykel Dishwasher Error Code F86

F86 indicates a motor bridge failure on the motor controller. The H-bridge circuit inside the controller, which is responsible for driving the wash motor, has failed. This prevents the dishwasher from running its wash or drain cycles. Replacing the motor controller is the prescribed corrective action.

No, the dishwasher should not be operated while displaying an F86 error. The motor controller failure means the wash motor cannot be properly controlled, so the appliance will not complete cycles. Attempting to run it repeatedly could stress other components or pose an electrical risk.

Repair costs depend on the price of the motor controller part and local labor rates. Parts alone can range from around $80 to $250 or more depending on the specific model, and professional labor charges typically add $100 to $200 on top of that. Getting a quote from a Fisher & Paykel authorized service provider before proceeding is recommended.

The repair requires replacing the motor controller, which involves working with line voltage components and disassembling the dishwasher's control systems. Knowledgeable DIYers who are comfortable with appliance electrical work can perform this replacement, but those unfamiliar with appliance repair should hire a qualified technician. Before replacing the controller, confirm the wash motor is not seized or shorted, as a faulty motor can damage a new controller.

A power reset is unlikely to permanently clear an F86 error because it points to a hardware failure in the motor controller rather than a temporary software or communication fault. The code may disappear briefly after a reset but will return once the appliance attempts to drive the motor. The motor controller needs to be physically replaced to resolve the fault.
