The dE2 error code means your LG washer's door is not latching or locking properly — the machine detects that the door has not fully closed and secured before the cycle begins. In most cases this is a simple DIY fix: an overloaded drum pushing against the door, a piece of clothing caught in the seal, or a misaligned door are the most common culprits. If the door closes completely but the code persists, the door latch assembly or door lock switch has likely failed and will need replacement.
LG washers will not start or continue a cycle unless the door is fully closed and electronically confirmed as locked. The machine uses a door lock switch (also called an interlock) to send that confirmation to the control board. The dE2 code fires when the board detects that the door has not locked within the expected time window after a cycle is initiated.
Note the distinction between dE and dE2: the basic dE code means the door was opened mid-cycle or never detected as closed. The dE2 code is more specific — it means the door is physically closed but the locking mechanism failed to engage or confirm. The door appears shut, but something is preventing the latch from clicking into the striker or the lock switch from signaling "locked."
Because the door physically closes most of the time, the root cause is often subtle: clothing bulging out of an overloaded drum, a worn door hinge causing slight misalignment, or a door boot seal that has shifted and is caught in the door frame. These are all quick, no-cost checks worth doing before assuming a part has failed.
Press and hold the Power button for three seconds to turn the washer off, then unplug it from the wall for one full minute. Plug it back in and try starting the cycle again. An occasional dE2 is caused by a momentary control board glitch that a power cycle clears entirely.
Open the door and remove roughly one-third of the laundry. Redistribute the remaining items so nothing is piled against the door opening. Close the door firmly — you should hear and feel a distinct click as the latch engages — then attempt the cycle again.
Run your hand around the entire circumference of the rubber door boot seal. Feel for any fabric, small items, or debris caught between the gasket and the door frame. Remove anything you find and gently press the gasket back into its groove if it has partially pulled away from the rim.
Look at the latch hook on the door and the striker plate recessed into the cabinet frame. Check for any visible cracks, chips, or deformation in the plastic. Confirm the striker plate is firmly seated and hasn't shifted. Close the door slowly and watch whether the latch hook lines up squarely with the striker opening.
Detergent residue and lint can build up inside the striker recess and around the latch mechanism, creating enough friction to prevent a clean lock. Wipe the striker cavity, latch hook, and surrounding door frame with a damp cloth. Dry thoroughly before testing.
Open the door to 90 degrees and release it — it should hold position without swinging freely or drooping noticeably. If it sags when released, the hinges have worn and the door is dropping out of alignment. Tighten any accessible hinge screws. If the hinge itself is bent or the screw holes have stripped, hinge replacement is required.
If every physical check passes but the dE2 code continues, the door lock switch (interlock) has almost certainly failed internally. This is a $20–$45 part that requires removing the door boot seal to access. If you're not comfortable with this repair, a technician can replace it in under an hour.

The basic dE code means the washer detected the door as open or not fully closed — the door wasn't shut before or during the cycle. The dE2 code is more specific: it means the door is physically in the closed position, but the locking mechanism failed to engage or the door lock switch did not send a "locked" confirmation to the control board. In short, dE is a door position issue; dE2 is a door locking issue.
You should not force the door. If the latch or striker is damaged, forcing the door can break the latch hook entirely and make the repair significantly more expensive. Instead, work through the steps above — reduce the load, check for trapped items, and inspect the latch — before applying any extra pressure to the door.
On a new machine, dE2 is almost always caused by an overloaded drum or a small item caught in the door seal during the first few loads. It is rarely a sign of a defective unit. Work through the first three steps (power cycle, reduce load, check the gasket) before contacting the retailer or LG support. If the code persists on an empty drum, that is grounds for a warranty service call.
The door lock switch (interlock) part costs $20–$45 depending on the LG model. If you replace it yourself, that is the full cost. Professional repair in the Boston area — including diagnosis, the part, and labor — typically runs $120–$220 with a 90-day warranty on the work.
