What to do when OE shows on the applianceKind of codeWater supply and drain
The new appliance is reporting what it gets from the water connections behind it. A no-water or slow-fill message on the first fill usually means the supply valve is still closed or only half open, or the new line kinked when the unit slid back; a drain message means the drain hose is pinched, pushed too deep into the standpipe, or looped higher or lower than the installation instructions allow. Open the valve fully, straighten the hose, set it to the height the manual gives, and run the cycle again.

New supply lines from a working quarter-turn stop to each water appliance, tested under pressure.

A drain backing up after an install leaves water standing in a new machine, pushes it into the sink or spills it over the top of the standpipe.

Before you book,
in this order.
Each step comes from LG's own guidance for OE on its appliances. Follow it to the end: the last card says whether this is a visit.
Check behind the washer to confirm the drain hose is not kinked or clogged.
Clean the drain pump filter, which is a routine step but especially likely to be overlooked right after a new install.
Confirm the drain hose height and routing match LG's installation instructions for this model.
If OE continues after these checks, book a visit rather than repeating cycles.
Still there?
It usually turns into water supply and shutoff connection. Book with the code and the model number.
What not to do
OE does not necessarily mean the drain pump itself has failed. LG's own documented causes are a kinked hose and a clogged filter, both of which are checked and cleared without a part.

A booking moves faster with three things: the message exactly as the display shows it, the model number from the carton or the rating plate, and the moment it first appeared. With those, the office can tell whether it is a setup step or a connection to put right, and send the part that fixes it.
