LG DE washing machine: what it means & what to check

Stop using it for now. Carrying on with this fault risks further damage or a leak. Switch it off at the wall until it has been looked at.

What DE actually means

Your LG washing machine can't confirm the door is shut and locked, so it won't start filling or spinning.

Before any cycle begins, the machine energises the door interlock and waits for confirmation that it has latched. If that confirmation doesn't come back, it stops and shows DE rather than risk running with an unsecured door. LG's own diagnostic test mode checks the door lock as one of its first steps, and a failed lock test brings up this same code.

What DE looks like on a LG washing machine

Most people find this page having searched for what the machine is doing rather than the code itself. On a LG washing machine, DE usually shows up as one or more of these:

Machine door won't open
Door won't lock or click shut
Door lock light flashing
Door stuck shut with the load inside
Won't start even with the door closed
Not filling with water
No water going in
Takes for ever to fill

Recognise any of those? That is this fault, and the rest of this page explains what causes it and what you can check yourself.

What usually causes it

Door not pushed fully shut, or something caught in the seal stopping it latching
Washing pushed against the door so the catch can't engage
Worn or broken door interlock (the most common finding by far)
Damaged or misaligned door catch/hook on the door itself
Wiring or control board fault feeding the interlock

What you can safely check yourself

Work through these in order. Anything beyond this — panels off, testing parts, anything to do with the wiring — is an engineer's job, and not one to attempt with the machine plugged in.

Open the door and close it again firmly, listening for the click of the latch
Check nothing — a sock, a corner of a duvet, the seal rolled over — is trapped between door and drum
Redistribute the load so it isn't pressing on the glass
Turn the machine off at the wall for a minute, then back on and retry the cycle
