Symptoms
- Clothes come out damp or still wet at the end of a cycle
- Drying takes far longer than the cycle time suggests
- Musty smell in clothes after drying
- Unit runs hot but doesn't seem to remove moisture well
Likely causes
- CommonOverloading the drumCombo units have less drying capacity than their wash capacity, and overloading is the most common reason for poor drying.
- CommonCondenser or heat exchanger needs cleaningVentless condenser dryers rely on a heat exchanger that collects lint and residue over time, reducing efficiency.
- PossibleVent blocked (on vented models)A blocked exterior vent restricts airflow needed to carry moisture out.
- PossibleWrong cycle selectedSome combo units have separate wash-only and wash-dry cycles, and picking the wrong one skips drying appropriately.
What to do
- Reduce the load size to about half of what you'd normally wash, since combo units typically need a smaller load to dry properly.
- Check the manual for your model's specific condenser or lint filter location and clean it thoroughly.
- For vented models, check the exterior vent hood and duct for lint blockage.
- Confirm you're selecting a wash-and-dry cycle rather than a wash-only cycle.
- Run an extended or extra-dry cycle option if your model has one, especially for thicker fabrics like towels.
- Clean the door seal and drum interior, since residue buildup there can also affect efficiency over time.
Tools and parts
- Vacuum with hose attachment
- Soft brush
When to call a pro
Call an appliance technician if drying stays poor after reducing load size and cleaning the condenser, since a heating element or sensor may need service.
