What the E310 error code actually means

Your Maytag washer has detected a serious electrical fault inside the part that controls how the motor speeds up and slows down. This is not a simple reset situation, and the washer should be turned off right away to avoid further damage. A component inside the motor control unit has failed and the unit will need to be replaced by a technician.

Questions people ask about E310

What does E310 mean on a Maytag washer?
E310 indicates a short circuit has been detected in the brake transistor circuit within the inverter board. The inverter board controls motor speed and braking, and a shorted brake transistor means this control has failed in a potentially dangerous way. The washer should be powered off immediately, and the inverter board must be replaced to resolve the fault.
Is it safe to keep using my Maytag washer with an E310 error?
No, it is not safe to continue using the washer when E310 is active. A shorted brake transistor represents an uncontrolled electrical fault in the motor control circuit, which can cause further damage to the motor, wiring, or other electronic components. Power the unit off immediately and leave it off until the inverter board has been replaced.
How much does it cost to repair a Maytag washer with an E310 error?
The cost to repair an E310 fault typically includes the price of a replacement inverter board plus labor for diagnosis and installation. Parts costs for inverter boards on Maytag washers generally range from around 150 dollars to 350 dollars depending on the specific model, with labor adding another 75 to 150 dollars depending on your location and the service provider. Getting a diagnostic visit from a certified technician before ordering parts is advisable to confirm no additional components were damaged by the short circuit.
Can I fix the E310 error myself on a Maytag washer?
Replacing the inverter board is a repair that requires working near high-voltage components, so it is best handled by a qualified appliance technician. If you have experience with appliance electronics and take proper safety precautions by unplugging the unit completely before starting, the inverter board is a replaceable assembly. However, individual transistor-level repair of the inverter board is not recommended because collateral damage to the board is common when a short circuit occurs.
Will resetting my Maytag washer clear the E310 error?
A reset will not clear the E310 error because the fault is caused by a physical short circuit in the inverter board hardware, not a software glitch or temporary sensor reading. The fault will return as soon as the washer attempts to operate the motor. The inverter board must be replaced before normal operation can resume.
