LG Washer Error Code DOOR OPEN

The DOOR OPEN error means the washer has detected that the lid is not properly closed during a spin cycle, intermittent spin, or a reservation (delayed start) cycle. The machine stops and signals the fault with blinking Wash and Spin LEDs and a continuous alarm. The washer will not spin until it confirms the lid is securely closed. The most common causes are a lid that is not fully shut or a missing magnet in the Lid-B assembly.

Closing the lid and restarting the cycle can clear the error if the root cause was simply an open or partially closed lid. However, if the underlying issue is a missing magnet or a damaged Lid-B assembly, the error will return as soon as the washer enters a spin phase. A reset alone will not correct a hardware fault.

If the fix is simply closing the lid or reseating a dislodged magnet, there is no parts cost involved. If the Lid-B assembly needs to be replaced, parts typically range from around 15 to 60 dollars depending on the specific model. Adding professional labor for the repair could bring the total cost to somewhere in the range of 80 to 175 dollars, though costs vary by region and service provider.

Start by firmly closing the lid and restarting the cycle to see if the error clears. If the error continues, inspect the Lid-B component on the lid for a small embedded magnet and confirm it is present and properly seated. If the magnet is missing or the Lid-B is damaged, replacing the Lid-B assembly is the recommended fix. If the Lid-B looks intact, the sensor on the washer body itself may need to be checked.

The washer is designed to prevent spinning with the lid open as a safety measure, so it will not complete the spin cycle while this error is active. Attempting to force or bypass the lid sensor is not recommended. Address the cause of the error before continuing to use the machine to avoid potential injury or further damage.
