LG Washer Machine Error Code: dE

There are 3 different dE error codes, dE, dE1 and dE2. All are indications that the door was unable to lock for some reason.

1. Check The Door

Start by ensuring nothing is blocking the door or the door latch. Sometimes, small objects can get in the way and prevent the door from closing correctly. If nothing is obstructing the door, make sure it is closed properly. Give the door a firm push to ensure it’s closed and the door latch is connected. Check if the DE error code is still showing. If so, move on to the next step.

2. Check The Door Latch

Inspect the door latch and surrounding area for visible damage or debris blocking it. If the latch is dirty, it might not engage properly, so clean it and then close the door firmly. Check if the DE error code is still showing. If so, move on to the next step.

3. Check The Door Gasket 

The rubber gasket around the door might be obstructing the door’s closure. Check for any tears, debris, or foreign objects that might prevent the door from sealing properly. If the door gasket is damaged, it will need to be repaired. If the door gasket is fine, move on to the next step.

4. Reset The Washing Machine

The next step is to do a simple reset. To reset your washing machine, switch the power off at the wall or turn the circuit breaker off. Once off, press the start/pause button for 5 seconds before turning the machine back on. You can then check if the DE error code is still showing. If so, you will need to inspect internal components or get a technician to do it for you.

5. Check The Door Lock Mechanism

The first internal component to check is the door lock mechanism. This spring-loaded device keeps the door latch in place, and your door securely closed. To check the door lock mechanism, locate it and check if the door latch locks into place correctly or if the component is damaged. If the door lock mechanism is malfunctioning, it will need replacement. If the door lock mechanism is fine or replacing it doesn’t remove the DE code, move on to the next step.

6. Check The Wiring

If you’re comfortable with electrical work, check the wiring and connections around the door lock mechanism to ensure no loose or damaged wires. If any wires are damaged, they will need to be replaced. If replacing the wires doesn’t remove the DE code or if the wiring is fine, move on to the next step.

7. Test The Door Latch Or Door Lid Switch

Front-loader LG washers have a door latch that ensures the door is closed, whereas top-loader washers have a lid switch for the same purpose. These components are electrical devices that monitor if the door is closed. If they become faulty, your door won’t shut properly, and the DE error code will be displayed. Checking the door latch or lid switch involves removing various panels (check your user manual) and then testing the switch with a multimeter. If the component is faulty, it will need to be replaced. If replacing the component doesn’t remove the DE code, you must call a technician to come and inspect your LG washing machine. They may recommend replacing the main control board if they cannot find any other faulty components. If this is the case, you may decide purchasing a new LG washing machine is cheaper.
