Maytag Washer Error Code F31

F31 means the motor's heat sink has exceeded 212°F (100°C). The CCU attempts to recover by resetting the MCU and waiting for the motor to cool, repeating this process up to four times before displaying the code and halting operation. It is a thermal protection fault designed to prevent permanent motor damage.

No, you should not continue running the washer when F31 is active. The code indicates the motor is overheating, and continuing operation could cause permanent damage to the MCU, the motor, or other electrical components. Allow the machine to cool completely before attempting any further use or diagnostics.

Costs vary depending on the root cause. If the fix is simply improving ventilation or adjusting usage habits, there is no parts cost. If the Motor Control Unit needs replacement, parts alone typically range from $80 to $200 or more depending on the model, with labor adding to that total if a technician is involved. A full diagnostic visit generally runs $75 to $150 before any parts are factored in.

In many cases, yes. Start by clearing the error code and unplugging the washer for at least 30 minutes to allow the motor to fully cool. Then confirm the washer has adequate ventilation and is not located near a heat source. If the error returns, further diagnosis of the MCU and drive components will be needed, which may require a technician.

A reset can clear the displayed code temporarily, but it will not resolve the underlying cause. The CCU already attempted an internal reset cycle up to four times before showing F31, so the code will return if the overheating condition has not been corrected. Address ventilation, load size, and mechanical issues before running the machine again.
