LG Dryer dE Error
Not to be confused with LG's washer dE, which is also a door code but on a different appliance with a different checklist — this page is the dryer one.
What to check first
- Seat the lint filter — LG's first dE check, ahead of the door itself.
- Clear clothing from the door opening and close the door firmly.
- New machine with a bent door → dealer, not troubleshooting.
- Reset once (5 seconds without power); dE again → service.
A dE code means door error: LG's dryer lists say the dryer is not completely closed. The causes LG names are more specific than “the door is open” — the lint filter not pushed all the way in and clothing stuck on the door are its first two checks, ahead of the door itself. On a brand-new machine LG changes the question entirely: look for damage, such as a bent door, and go back to the dealer. Everything else gets one reset — unplug or trip the breaker, wait 5 seconds, close the door firmly and start a cycle — and a dE that survives it needs service.
Safety first
- Do not tape, wedge or otherwise defeat the door switch to keep a cycle running — dE is the machine reporting that its door circuit cannot confirm a sealed drum, and LG publishes no override.
- Stop condition: stop using the machine and unplug it — and do not run it again until it has been checked — if you smell burning, see smoke, find damaged electrics (a scorched plug, a melted or cut cable), or water is leaking in quantity.
Common causes
The lint filter is not pushed all the way in
LG's first check on both lists: open the door and make sure the lint filter is pushed all the way in. The filter sits in the door opening on LG dryers, and a filter left slightly out holds the door off its seal.
Clothing stuck on the door
LG's second check: an item caught in the door edge stops it closing flush. Clear the opening, redistribute the load so nothing sits in the doorway, and close the door firmly.
A bent door or damaged frame — new machines
LG's UK list asks it directly: if the unit is brand new, is there any noticeable damage to the frame, such as a bent door? If so, contact the dealer — that is a delivery-damage case, not a troubleshooting case.
Step-by-step checks
- Open the door and seat the lint filterPush the lint filter all the way into its housing — LG's first check for dE on both its lists.
- Clear the door openingRemove any clothing stuck on the door, and close the door firmly.
- Brand-new machine? Look for damage firstA bent door or damaged frame on a new unit goes back to the dealer, per LG — skip the reset and call them.
- Reset the unit onceUnplug the dryer or trip the circuit breaker, wait 5 seconds, plug it back in, close the door firmly, select any cycle and press Start. (LG UK's numbered sequence.)
- If dE displays again, book serviceLG's endpoint on both lists: a dE that returns after the reset means the unit will need service.
When to call a technician
Service is LG's stated endpoint when dE survives its checks and one reset — at that point the door switch, latch or alignment needs a technician, and LG publishes no user adjustment for them.
Quote the exact code — dE — and say whether the machine is new (dealer route) or established (service route); LG's own lists split the two cases.
Model differences
| What you have | What changes |
|---|---|
| Brand-new dryer | Damage check first: a bent door or frame damage is a dealer case (LG UK), not a reset case. |
| Washer showing dE instead | Same letters, different appliance and a different checklist — see the LG washer dE page. |
One-page checklist — dE
- Code read as dE (door error)
- Lint filter pushed all the way in
- Door opening clear — no clothing stuck; door closed firmly
- New machine: door/frame checked for damage (dealer if bent)
- One reset done: power off, 5 seconds, restart
- Code returned → service booked, dE quoted

Frequently asked questions
The door looks shut. Why dE?
Because LG's dE is about the door circuit, not your eyes: its first two published causes are the lint filter not pushed all the way in and clothing stuck on the door — both hold the door a few millimetres off its seal. Work those two checks before suspecting the door itself.
Is dryer dE the same as washer dE?
Same letters, different appliance. LG publishes separate dE checklists: the washer's turns on the door lock and load; the dryer's turns on the filter seating, the door opening and a 5-second reset. This page is the dryer's; the washer's is here.
I reset it and dE cleared. Fixed?
LG's sequence treats the reset as a test: if the dryer displays dE again, it will need service. A code that clears once and returns is the service case LG describes.
