What E31 means on a Midea washer

The E31 error code on a Midea washer indicates that the door lock mechanism has failed to release after three consecutive unlock attempts. The washer's control board monitors the door lock actuator and its feedback signal after each cycle. When the latch solenoid or motor receives the unlock command but the door lock switch does not confirm an open state within the allowed attempts, the board logs E31 and halts further operation to prevent the drum from being accessed under unsafe conditions.

The most common root cause is water remaining in the drum. Midea washers are designed to keep the door locked when water is present as a safety interlock. If the drain pump has failed, the drain hose is kinked or clogged, or the cycle was interrupted mid-drain, residual water triggers the lock to stay engaged regardless of unlock commands. Manually draining the machine through the service panel filter port is the first required step before any other diagnosis.

If the drum is confirmed empty and E31 persists, the fault typically points to a failed door lock assembly, a broken or disconnected wiring harness between the lock and the control board, or a failing control board that is not sending a clean unlock signal. The door lock mechanism contains an internal microswitch that reports lock status back to the board. A damaged switch, worn actuator, or corroded connector can cause a mismatch between the commanded and reported states, resulting in repeated failed unlock attempts and the E31 fault.

Common causes of E31

  1. 01

    Water remaining in the drum

    Wiring / connection

    The washer keeps the door locked as a safety measure whenever water is detected inside. A failed drain pump, clogged drain filter, or kinked drain hose can leave standing water that prevents the door from unlocking.

  2. 02

    Failed door lock assembly

    Part replacement

    The door lock contains an internal microswitch that signals the control board when the latch has released. If the actuator motor or microswitch inside the lock assembly has worn out or failed, the board never receives a confirmed unlock signal and keeps triggering E31.

  3. 03

    Wiring harness fault at the door lock

    Wiring / connection

    A broken, pinched, or corroded connector between the door lock and the main control board can interrupt the feedback signal. Inspect the harness and connector pins at both the lock and the board for damage or corrosion.

  4. 04

    Clogged drain pump filter

    Wiring / connection

    The drain filter located behind the service panel at the front bottom of the machine can become blocked with debris, preventing proper drainage and causing residual water to keep the door lock engaged.

  5. 05

    Control board malfunction

    Part replacement

    If all other components check out correctly, the main control board itself may be failing to send a clean unlock command to the door lock actuator. This is the least common cause and is typically diagnosed only after ruling out all other possibilities.

Frequently asked questions about E31

What does E31 mean on a Midea washer?
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.
How do I fix the E31 error on my Midea washer?
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.
Is it safe to leave a Midea washer showing E31?
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.
Will resetting my Midea washer clear the E31 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.
How much does it cost to repair a Midea washer with an E31 error?
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.
