Quick answer: An LG washing machine showing dE — DE on some displays — cannot confirm that the door is closed and locked, so it will not start, or has stopped mid-cycle. The two most common causes are something caught in the door (a sock, a strap, a folded door seal lip) and a worn door lock switch that no longer registers the latch. Open the door, clear the seal and latch area, and close it again firmly until it clicks. If dE persists on a door that shuts cleanly, the lock switch is the usual fix.
What the dE code means
A front loader locks its door before it lets any water in, and keeps it locked until the cycle ends. A small interlock — the door lock switch — sits behind the front panel at the latch and tells the control board the door is shut and secured. dE means the board never received that signal, or lost it partway through a cycle. On most models dE and DE are the same fault shown by different display generations, and some top loaders raise the same family of fault when the lid locker cannot engage.
The useful thing about dE is that the machine is not accusing any of its major parts — not the motor, not the pump, not the board. The fault sits somewhere in the few centimetres between the latch on the door and the switch in the cabinet, and most of the causes cost nothing to fix. If your display is showing something else entirely, start at the full LG washing machine error code guide and work from there.
Check these before replacing anything
Switch the machine off at the power point before working around the latch. Then go through the list in order — it starts with the causes that cost nothing.
- Clear the door opening. A sock, a bra strap or a hoodie drawstring flopped over the latch — or pinched between the door glass and the seal — is the single most common trigger. Open the door, pull everything clear of the rim and close it again firmly until you hear the click.
- Check the door seal. Run a finger around the rubber door seal, especially near the latch. A lip folded over on itself can hold the door a few millimetres proud of the cabinet — enough for the latch to miss the switch. Ease the fold back into shape and try again.
- Test for door sag. Close the door while lifting it gently by its outer edge. If dE only clears when you lift, the hinge has dropped and the latch is arriving at the wrong height. On most models snugging up the hinge screws brings it back into line.
- Look into the latch slot. Lint, detergent grit or a chipped latch tongue will stop the lock engaging. Clean out the slot in the cabinet and check that the tongue on the door is not cracked or wobbly.
- Do a 10-minute power reset. Switch off at the power point, wait ten minutes and try again. The lock module can hold onto a fault after a power hiccup, and on most models a full reset clears it.
The parts that actually fix a persistent dE
The door lock switch earns its keep: it clamps and releases the door every single cycle, and its small contacts and levers wear out long before the rest of the machine. When it can no longer say “locked” reliably, you get dE on a door that looks and feels perfectly shut — intermittently at first, then every load. Front loaders and top loaders use different lock designs, and front-loader switches differ between series — the LG WV series parts guide and the WTG / WTS top loader parts guide cover the two big families. Match the switch to your model.

 Top loader lid will not lock — WTG9530S / WTG9532VH / WTG9532WH | Lid locker switch assembly | LG top loader locker switch assembly (WTG9530S / WTG9532VH / WTG9532WH) |

On most front loaders the switch comes out through the door opening: peel back the outer edge of the door seal near the latch, undo the two screws beside the latch slot and work the switch out far enough to swap the wiring connector — no cabinet teardown required. Top-loader locker assemblies sit under the top panel beside the lid and are a similarly contained job.
Find the exact part for your model
Your model number is on the model sticker — around the door opening on most front loaders, and on the back panel or under the lid on most top loaders. The guide to finding your LG model number shows exactly where to look for each machine type. With the number in hand, drop it into the Find Your Model page, or answer a few quick questions in the Part Finder quiz and it will point you at the right lock switch for your machine.
FAQ
Why does my LG washer show dE when the door is firmly shut?
Because “shut” and “registered as locked” are two different things. A folded seal lip or a sagging hinge can leave the latch a few millimetres out of line, and a worn lock switch can fail to register a latch that is perfectly seated. Work through the seal, hinge and latch checks first; if the door closes cleanly and dE continues, the switch itself is the likely fault.
Are dE and DE different codes?
No — on most models they are the same door fault shown by different display generations. Whichever version your machine shows, the checks are identical: clear the door opening, reseat the seal, check the hinges and latch, then suspect the lock switch.
The door won’t open at the end of the cycle — is that the same fault?
Usually not. A door that stays locked after the cycle generally means the machine still senses water in the drum, which is a drain problem rather than a door problem — especially if it comes with an OE code. Start with the LG OE error code guide in that case. dE is the opposite situation: the machine cannot lock the door in the first place.
Can I bypass the door lock switch to keep washing?
No — the interlock is what keeps the door sealed while the drum spins at high speed, and the machine is designed not to run without it. The good news is that replacing the switch is one of the more contained repairs on a front loader: on most models it swaps through the door opening with a couple of screws, no cabinet removal needed.
