What the appliance detected
Detected condition
The hybrid condensing dryer detected a drain problem involving the drain hose or sump-water condition.
What may contribute
Possible causes
- The visible drain hose is kinked, twisted, crushed, or clogged at an accessible point.
- The drain hose has been extended in a way that increases resistance.
- Water in the sump may be frozen in cold conditions.
- An internal drain-system condition may require service.
Start conservatively
Safe preliminary checks
Work in order and stop whenever a step is not supported by the documentation for your model.
Confirm the model is a hybrid condensing dryer
- Photograph E13 and record the complete model number.
- Check the model manual or LG product support to confirm that E13 is defined for that dryer.
Inspect the visible drain hose
- Turn the dryer off before checking the accessible hose for kinks, twists, crushing, or an obvious blockage at the outlet.
- Do not remove panels, reach into the sump, or disassemble the drain system.
Check the installation against the manual
- Confirm that the drain hose route and any extension match LG model-specific installation instructions.
- After correcting only an accessible installation issue, press Start/Pause once to retry as LG directs.
Actions not recommended
- Do not open the dryer to access the sump, pump, internal hoses, wiring, or sensors.
- Do not use heat guns, open flames, boiling water, or other improvised methods to thaw internal water.
- Do not assume E13 means the drain pump must be replaced.
When to stop and request service
- E13 returns after accessible hose and installation checks.
- The hose cannot be safely cleared or shows damage or leakage.
- Frozen internal water, a pump concern, or any internal drain-system diagnosis is suspected.
