Quick answer
If your LG ventless washer dryer combo isn't drying, first check for lint buildup in the filter and drum. Ensure the load isn't too large or too small, and confirm the drying cycle is selected. If the issue persists, inspect the heating element and moisture sensor.
Confirm the symptom
- LG ventless washer dryer combo
- Wet clothes after full drying cycle
- Normal washing but poor drying
- No heat during drying phase
- Drying cycle completes but clothes remain damp
Tools and prep
- Screwdriver (if needed for filter access)
- Lint brush or vacuum
- Clean cloth or towel
- Owner's manual
- Safety gloves
- Ensure unit is unplugged before inspecting internal components
Step-by-step troubleshooting
- Check Lint FilterDo: Remove and clean the lint filter thoroughly.Observe: Excessive lint buildupMeans: Blocked airflow restricts drying efficiency.Next: Clean filter and rerun a short drying cycle.
- Inspect Drum and VentsDo: Use a lint brush or vacuum to clean the drum and internal vents.Observe: Lint or debris in drum or vent channelsMeans: Airflow obstruction prevents proper drying.Next: Proceed to check load size and settings.
- Verify Load SizeDo: Ensure the load is neither too large nor too small.Observe: Overloaded or underloaded drumMeans: Improper load distribution hinders drying performance.Next: Adjust load and restart drying cycle.
- Check Drying SettingsDo: Confirm the correct drying cycle is selected (e.g., cottons, synthetics, or timed dry).Observe: Incorrect or default cycle settingsMeans: Cycle may not provide sufficient heat or time for the fabric type.Next: Select appropriate cycle and rerun drying.
- Test Heating ElementDo: Use a multimeter to test the heating element for continuity.Observe: No continuity or damaged elementMeans: Faulty heating element prevents heat generation.Next: Replace the heating element if defective.
- Inspect Moisture SensorDo: Check the moisture sensor for dirt or damage.Observe: Dirty or corroded sensor contactsMeans: Malfunctioning sensor may terminate cycle too early.Next: Clean or replace the moisture sensor.
- Check Drain Pump FilterDo: Access and clean the drain pump filter if applicable.Observe: Clogged filter with lint or debrisMeans: Restricted drainage can impact drying performance.Next: Clean filter and monitor drying results.
- Reset the UnitDo: Unplug the unit for 1 minute, then plug back in.Observe: Unit resets to default settingsMeans: Electrical glitch may have disrupted drying function.Next: Run a test cycle to confirm resolution.

FAQ
How often should I clean the lint filter?
Clean the lint filter after every cycle for optimal performance.
Can I use a regular vacuum to clean internal vents?
Yes, a low-suction vacuum with a narrow attachment works well for vents.
Why does my combo unit stop drying after a few minutes?
A faulty moisture sensor or electrical issue may be causing premature cycle termination.
Is it safe to run the dryer without the lint filter?
No, the lint filter is essential for airflow and fire prevention; never operate without it.
How do I reset my LG ventless combo?
Unplug the unit for 1 minute, then plug it back in to reset.
