We closed the door, pressed “Start”, and instead of tak­ing water, the DE code appeared on the dis­play. Basi­cal­ly, this error appears at the begin­ning of the wash. What to do? What does DE error mean in LG wash­ing machine? How to fix the prob­lem your­self? You will find answers to all these ques­tions in this arti­cle.

Error decoding

LG washing machine gives a DE error

Error DE means that the wash­ing machine door is not closed or the hatch lock does not work. The main cause of the mal­func­tion is the hatch block­ing device (UBL), but the hinges, han­dle, latch hook, or con­trol mod­ule may also be faulty.

On LG wash­ing machines with­out a dis­play, the DE code is indi­cat­ed: all tem­per­a­ture indi­ca­tors, wash­ing mode and rinse are flash­ing or lit at the same time. Such sig­nals indi­cate that the hatch door is not closed.

How to fix the error yourself

It would seem that the cause of the mal­func­tion is known and it is enough to close the hatch more tight­ly. Often, such actions are enough and the prob­lem dis­ap­pears. Oth­er­wise, the mal­func­tion occurs for a more seri­ous rea­son:

  • Break­age of the latch hook, sun­roof lock­ing device
  • Dis­place­ment spring or clamp, sun­roof lock­ing devices
  • Mal­func­tion of the elec­tron­ic sen­sor of the sun­roof lock device
  • Wash­ing machine con­trol board mal­func­tion


The most com­mon caus­es of the error are list­ed here, oth­er less­er-known break­downs are pos­si­ble, and for their exact deter­mi­na­tion, it is rec­om­mend­ed to call a spe­cial­ist.

In cas­es where a DE code occurs, it is rec­om­mend­ed to car­ry out a series of sequen­tial actions that can help get rid of the error on your own.

  • To begin with, it is worth check­ing the tight­ness of the clos­ing of the hatch, per­haps it is not closed. To do this, you just need to press it hard­er.
  • You should also inspect the entire door for exter­nal obstruc­tions.
  • Inspect the hatch door from the inside, cloth­ing may have fall­en between the load­ing hatch and the drum and pre­vent it from clos­ing tight­ly. You should also pay atten­tion to the latch tab, per­haps there are objects on it that pre­vent clos­ing.
  • Check the hatch door for dis­tor­tions, if they are found, it is nec­es­sary to tight­en the side hinges.
  • If none of the above is found or does not help, you should per­form a com­plete reboot of the wash­ing machine. To do this, fol­low these steps in sequence: open the hatch, unplug the machine from the mains by pulling the plug out of the sock­et, wait 15–20 min­utes, then recon­nect the machine and close the hatch.

If after per­form­ing the above steps the error per­sists, then it makes sense to con­sid­er oth­er caus­es of the mal­func­tion.

Faults requiring repair

Use the fol­low­ing table to deter­mine the cause of the error:

Descrip­tion of the prob­lem Cause of error Solu­tion
The hatch door does not close com­plete­ly and is not fixed. Latch hook bad­ly worn or bro­ken Replac­ing an ele­ment
The door clos­es and locks, but the machine does not start the wash­ing pro­gram. The lock­ing device is out of order Replac­ing an ele­ment
In the wash, rinse or spin mode, the wash­ing machine stopped work­ing and gave a DE error. There is a burn­ing smell. Faulty con­trol mod­ule. Most often, the micro­cir­cuit “suf­fers” due to burnout of con­tacts dur­ing pow­er surges or due to water ingress into elec­tron­ics. It is nec­es­sary to remove the front pan­el by dis­man­tling the upper part of the machine. Then take out the board. Dam­aged places are imme­di­ate­ly vis­i­ble — they turn black, the caps of the capac­i­tors become con­vex, traces of breaks are vis­i­ble. If a defec­tive part is found, it is sol­dered, and a new one is installed in its place.
The han­dle does not work and the door does not lock. Han­dle break­age Replac­ing an ele­ment
The hatch door does not close and there is a skew Hinge wear Hinge adjust­ment or com­plete replace­ment


Mal­func­tions in the oper­a­tion of the wash­ing machine are not exclud­ed from its life cycle. There­fore, in the event of a com­mon error, peo­ple who read this arti­cle will be ful­ly able to deter­mine the cause of the incon­ve­nience and will often be able to cor­rect them­selves. But it’s always bet­ter to avoid an error than to fix it. So do not for­get about the rules of oper­a­tion and respect.
