Midea Washer Error Code E31

E31 means the washer has attempted to unlock the door three times and failed each time. The control board shuts down further unlock attempts and displays E31 as a safety precaution. The most frequent reason is water still present in the drum, which the machine is designed to keep sealed. Once the water is drained, the door should release normally.

The machine locks itself down specifically to prevent unsafe access, so it is not dangerous in the short term. However, leaving standing water in the drum for an extended period can lead to mold and mildew growth inside the tub. You should drain the water and resolve the underlying fault as soon as possible.

If the fix is simply clearing a clogged drain filter or straightening a kinked hose, the repair costs nothing beyond your time. Replacing a door lock assembly typically runs in the range of $30 to $80 for the part, plus labor if a technician is hired. A control board replacement is the most expensive scenario, generally ranging from $100 to $250 or more depending on the specific model.

Start by draining any water from the drum using the service panel drain filter at the front bottom of the machine. After draining, attempt to open the door again. If the door still will not open and E31 returns, inspect the door lock wiring harness for damaged or corroded connectors, and test the door lock assembly itself. A faulty door lock assembly will need to be replaced to resolve the error.

A power reset may temporarily clear the error display, but E31 will return if the underlying cause has not been resolved. If water is still in the drum or the door lock assembly is faulty, the code will reappear as soon as the washer attempts to run or unlock the door again. Address the root cause first before relying on a reset.
