Error codeHS
ApplianceDryer
Quick answer
HS on an LG dryer is a humidity sensor error. Cleaning the sensors below the lint filter is the manual's first step.
Model compatibility: LG reuses codes across series and model years, so HS may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Humidity sensor error; dryer runs about 2.5 hours.
An HS code on an LG dryer means the machine has detected an error with its humidity sensor. With HS showing, the dryer runs for about two and a half hours, which can make it seem as if the dryer is simply not drying.
Cleaning the sensors
Use a damp rag or paper towel to wipe the sensors on the inside of the dryer, located below the lint filter. Let them dry completely before you start another cycle.
If HS comes back, the dryer may need a repair visit.
F0 is the message for a lint filter that is out of place.
nd is a no-drain message, from a clogged drain hose or debris filter or a kinked vent hose.
