LG Washer Dryer: not washing or drying effectively
What is this symptom?
If your LG washer dryer combo is not washing or drying effectively, you may notice clothes coming out still dirty or damp. This issue is often due to overloading, incorrect cycle settings, or airflow restrictions, impacting the performance of your appliance. Understanding these common causes can help you restore its efficiency.
Important Tips for LG Models
- LG washer dryer combos use condense or heat pump drying systems that require proper drainage and internal airflow; poor hose routing and load sizes disproportionately affect drying performance
Possible Causes
Overloading the drum
How to Identify: Loads larger than recommended capacity, clothes bunched together, uneven wetness or cleaning
Part: Drum/load capacity
Incorrect cycle settings or load type
How to Identify: Using gentle or improper cycle settings that are not suited for soil level; heavy items selected on low heat or cold settings
Part: Control settings/Program selection
Clogged lint filter or restricted airflow
How to Identify: Visible lint buildup on filter, slower drying times, damp spots after drying, error or long cycle times
Part: Lint filter/airflow path
Internal airflow or heat pump inefficiency (combo models)
How to Identify: Extended drying times despite clean lint filter and proper load, persistent dampness
Part: Heat pump/airflow internals
DIY Solutions
Reduce Load Size and Arrange Evenly
- Unload some items to reduce drum filling to about half to two‑thirds capacity
- Redistribute clothes evenly in drum so they can tumble freely
- Select appropriate wash/dry cycle for the load type
Clean Lint Filter and Accessible Air Paths
- Locate lint filter (usually inside door opening or top of drum)
- Remove accumulated lint by hand or brush
- Rinse filter under warm water if clogged and dry before reinstalling
Clean Washer Tub and Dispenser
- Run a dedicated tub clean cycle or hot water wash with cleaner
- Wipe inside of drum and detergent dispenser drawer to remove buildup
- Leave door open after cleaning for ventilation
Check and Straighten Drain Hose
- Unplug machine from power
- Locate drain hose at rear and ensure it lies flat with no kinks
- Ensure hose height does not form a high U‑trap which blocks drainage
