Whirlpool Washer Error Code F31

F31 means the motor control unit heat sink has exceeded 212°F (100°C). The washer's control system detects this overtemperature condition, resets the motor controller, and waits for the motor to cool before attempting to restart. This protective cycle can repeat up to four times before F31 is displayed and the washer halts operation.

No, you should not continue running the washer while F31 is active. The error indicates the motor control electronics reached a dangerous temperature, and continued operation could cause further damage to the MCU or motor. Allow the unit to cool completely and resolve the underlying cause before running another cycle.

Repair costs vary depending on the root cause. If the fix involves improving ventilation or reducing load size, there is no parts cost. Mechanical repairs such as replacing a drum bearing or drain pump typically range from $80 to $200 in parts. Replacing a faulty MCU can range from $100 to $300 or more for the part alone, with additional labor costs if a technician is hired.

In many cases, yes. Start by clearing the code, unplugging the washer, and allowing it to cool for at least 30 minutes. Then verify the washer has proper ventilation clearance and is not located near a heat source. If the error returns after addressing those factors, further diagnosis of the drive system or MCU may be needed, which can require more advanced repair skills.

Unplugging the washer or disconnecting power can clear the stored fault code, but it will not fix the underlying cause. If the condition that triggered the overheating is still present, the washer will repeat its four-attempt cool-and-restart cycle and display F31 again. A lasting fix requires addressing ventilation, mechanical, or component issues.
