Maytag Washer Error Code E31

E31 indicates an initialization fault in the frequency inverter, which is the component that controls motor speed and power. The inverter failed to load the correct parameter settings when the washer started up. This prevents the washer from operating to avoid potential damage to the motor or inverter. The machine will not run until the fault is resolved.

No, you should not continue operating the washer while E31 is active. Incorrect inverter parameter settings can cause the motor to run outside its designed operating conditions, which may lead to overheating, mechanical damage, or further electrical damage to the inverter and control board. Wait until the fault has been properly diagnosed and resolved.

Repair costs vary depending on the root cause. If the issue is resolved by a technician reprogramming or reconfiguring the inverter, labor costs typically range from around $80 to $150. If the frequency inverter itself needs replacement, parts and labor combined can range from $200 to $450 or more depending on the specific model and local labor rates. A control board replacement, if required, falls in a similar range.

The first step is to switch the washer off, wait a minute, and restore power to allow the inverter to attempt reinitialization. If the code clears and does not return, the fault was likely caused by a transient power event. If E31 returns after the power cycle, a qualified technician should inspect the washer before you use it again, since the underlying cause may involve the inverter or control board.

A power cycle, turning the washer off and back on, may clear the code if the fault was triggered by a brief power interruption or similar transient event. However, if the inverter's parameters are genuinely corrupted or if there is a hardware fault, the error will return after the reset. A recurring E31 after multiple resets requires professional diagnosis.
