LG Dryer Error Code nd — No Drain (Condensation Dryer)
What this means
The nd (no drain) error code on LG condensation dryers indicates that the unit cannot properly drain the condensed water it collects during the drying process. This is typically caused by a clogged drain hose, a kinked or crushed vent hose, or a full condensation collection tank. Unlike vented dryers that push moisture outside, condensation models collect water internally, and this system must drain properly for the dryer to operate.
Alternate codes: ND
Step-by-step fix
3 stepsEmpty the condensation tank
Pull out the condensation collection tank (usually located at the top of the dryer). Empty the water into a sink or bucket, then rinse the tank and reinsert it securely.
Check the tank after every drying cycle in humid conditions to prevent overflow errors.
Check the drain hose
If your condensation dryer is connected to a direct drain, inspect the drain hose at the back of the unit. Look for kinks, twists, or clogs. Disconnect the hose and flush it with water to clear any blockages.
The drain hose should slope downward continuously — any upward loops can trap water and trigger the nd error.
Clean the debris filter and condenser
Remove and clean the lint filter. Also access the condenser unit (usually behind a lower panel) and rinse it under running water to clear lint and dust buildup that can impede drainage.
Clean the condenser every 1–2 months. Accumulated lint restricts airflow and can cause both nd and overheating errors.
When to call a professional
If the drain path is clear and the tank is empty but the nd error persists, the internal drain pump or water level sensor may be malfunctioning and requires professional service.
