On the covered LG dryer platform, dE, dE4 means the dryer door is not completely closed — LG's own wording. LG also names a misaligned door as a cause. First, open the door, check the filter is pushed all the way in, and check no clothing is caught on the door.

Exact questions
Common questions
What does dE, dE4 mean on a LG dryer?+
the dryer door is not completely closed — LG's own wording. LG also names a misaligned door as a cause.
How long do I wait during the reset?+
5 seconds.
Can the filter cause it?+
Yes; push it all the way in.
Does slamming the door harder fix it?+
No — LG's own steps treat this as a detection problem, not a latch-strength problem, so forcing the door only risks damaging the frame on a unit that is otherwise fine; clearing the filter and anything caught in the door is the actual fix, with the reset reserved for when the door and filter both check out.
