Fisher & Paykel Washer Error Code F3

The F3 code means the washer has detected a water temperature above 176°F, which exceeds its safe operating limit. The fault can be caused by a heating element stuck in the on position, a failed temperature sensor, an ADC fault on the control board, or incoming supply water that is already too hot. The machine stops the cycle to prevent damage to clothing and internal parts.

No, you should not continue running the washer while F3 is active. Water above 176°F can damage fabrics, degrade internal seals and hoses, and pose a burn risk when the door is opened. The machine stops the cycle as a safety measure, and it is important to identify and correct the underlying cause before attempting to run another load.

Repair costs vary depending on the faulty component. A replacement temperature sensor is generally the least expensive fix, typically ranging from $20 to $60 for the part. A new heating element usually falls in the $40 to $100 range. Control board replacement is the most costly option, often ranging from $150 to $350 or more depending on the model, plus labor if a technician is involved.

Some causes of F3 are DIY-friendly. You can check your hot water supply temperature with a thermometer to rule out a supply-side issue at no cost. Testing or replacing the temperature sensor is a moderate-difficulty repair that many experienced DIYers can perform. However, diagnosing a control board ADC fault or safely replacing a heating element involves working with electrical components, so those repairs are better handled by a qualified technician.

A power reset may temporarily clear the F3 code and allow the machine to start, but the fault will return if the underlying cause has not been addressed. If the heating element is shorted or the sensor is faulty, the same over-temperature condition will recur during the next wash cycle. A reset is only a useful first step to confirm whether the fault is intermittent or persistent.
