LG Washer Error Code DOOR LOCK

The DOOR LOCK error means the washer's control system cannot confirm that the door is properly closed and latched. The machine requires a verified locked door before it will begin or continue a wash cycle. This is a safety feature to prevent the drum from spinning with an open or unsecured door. The error can result from a door not fully pushed shut, an obstruction in the door seal, or a faulty door latch assembly.

No, the washer will not operate while the DOOR LOCK error is active, which is by design. Running the machine with an improperly secured door could result in water leaking onto the floor or the door opening during a spin cycle. Do not attempt to bypass or force the lock mechanism. Diagnose and resolve the root cause before resuming use.

If the fix is simply closing the door properly or removing an obstruction, there is no parts cost involved. If the door latch assembly needs replacement, parts typically range from $15 to $60 depending on the model, with professional labor adding $75 to $150 or more depending on your area. Wiring repairs or control board replacement would fall at the higher end of the repair cost spectrum.

Start by pushing the door firmly closed until you hear a click, then try restarting the cycle. Check the door boot seal for any clothing or debris that might be blocking a full close. If the error continues, inspect the door latch assembly for visible damage or looseness, and check the wiring connector at the latch for any loose or corroded pins. If the latch assembly is defective, it will need to be replaced.

A reset may temporarily clear the error code, but if the underlying problem is not resolved, the error will return when you attempt to run a cycle. To reset, unplug the washer for about 30 seconds and plug it back in. If the door latch or wiring has a physical or electrical fault, a reset alone will not fix it.
