Fisher & Paykel Washer, Dishwasher, Oven Error Code 41

Error code 41 on a Fisher & Paykel washer, dishwasher, or oven indicates a temperature sensor fault. The appliance has detected that the signal from the temperature sensor is outside the expected range, which could mean the sensor has failed, the wiring is damaged, or a connector has come loose. The appliance stops the cycle to prevent operating at an incorrect temperature.

It is not recommended to continue operating the appliance when error code 41 is active. Because the temperature sensor is used to regulate heat during a cycle, running the appliance without a working sensor could result in overheating, undercooking, or damage to internal components. The appliance should be diagnosed and repaired before returning it to normal use.

A power reset, such as unplugging the appliance for a few minutes, may temporarily clear error code 41, but the fault will return if the underlying problem with the temperature sensor or its wiring is not resolved. A reset is useful to confirm whether the fault is intermittent or persistent, but it is not a substitute for a proper diagnosis and repair.

Some causes of error code 41 are DIY-friendly, such as reseating a loose connector or cleaning a contaminated sensor. However, testing a thermistor with a multimeter and interpreting resistance values requires some technical knowledge and basic tools. Replacing a sensor is a moderate repair, but if the control board is the cause, that is typically a job for an experienced technician.

Repair costs depend on the root cause. A replacement temperature sensor is generally an affordable part, with DIY repair costs typically ranging from $15 to $60 for the part alone. If a technician is needed for diagnosis and installation, total costs including labor can range from $100 to $250. A control board replacement, if required, can push costs considerably higher.
