On the covered LG dryer platform, d r n, drn, OE means the water container is full, the drain hose is kinked or pressed, or the drain pump is filled with air — LG's own three causes for this code. First, check the water container is empty and fully inserted; pull it out level with both hands, empty it, and push it back until it clicks.
Differential
Likely causes of “LG dryer code d r n, drn, OE”, and how to tell them apart
- 1
A full water container
What separates it The dryer stopped mid-cycle with drn or OE, which points to a full water container
How to confirm Slowly pull the container out holding it horizontally with both hands, empty it, and push it back until you hear a click
- 2
A kinked or pressed drain hose
What separates it The hose is twisted or blocked behind the dryer
How to confirm LG says the dryer can shift and twist the hose; straighten any bends
- 3
A drain hose installed too high
What separates it The hose end is above 1 meter or submerged
How to confirm LG says the height from the floor to the top of the hose must not exceed 1 meter and the hose should hang onto a hard, even surface
- 4
Air in the drain pump
What separates it The container is empty and the hose is clear
How to confirm Empty residual water using the Air Dry cycle
Before you touch a setting
Record this first — changing settings destroys the evidence
- The exact characters shown on the display: drn or OE
- Whether the water container is full
- How the drain hose is routed

0 of 6 completedWhat to do first
ReversibleCheck the water container is empty and fully inserted; pull it out level with both hands, empty it, and push it back until it clicks.
Correct only the documented fault domain
ReversibleStraighten any bend in the drain hose and check it is not pressed or installed too high — LG notes vibration can twist or kink it during operation.
Empty the water container
ReversibleIf the container is full, pull it out slowly, holding it horizontally with both hands, empty it, and insert it until you hear a click. Check that it is empty before every cycle.
Straighten the drain hose
ReversibleStraighten any bends, keep the height from the floor to the top of the hose below 1 meter, and let the hose hang onto a hard, even surface.
Remove residual water
ReversibleSelect Air Dry and press Start/Pause; after 2 to 3 minutes press Power. Or, on models with a drain hose, put it in a pan, turn the cap counterclockwise, let the water drain, close the cap and reattach the hose.
Restart and watch
ReversibleIf the error persists with the container empty and the hose clear, request service; if the dryer stops again after 10 to 20 minutes, it needs inspection.
