What is true of this model and changes how you fix it
- Type — all-in-one washer + ventless heat-pump DRYERThis is not just a washer: the WashCombo washes AND dries in one drum, with a VENTLESS heat-pump dryer — no exhaust duct. So a 'not drying' complaint is a heat-pump and its condensate/filter question, not a vent, and clothes come out warm/damp-free rather than hot. Diagnose whether the fault is in the wash, drain, spin or dry stage first.
- Ventless drying implicationsBecause it condenses moisture instead of venting it, the heat-pump has a lint filter AND a condenser/drain path that both need cleaning; a gradually poorer dry is usually a clogged filter or condenser, not a failed heater. It also dries at lower temperatures, so a full dry takes longer than a vented dryer — that is normal.
- Motor & smartDirect Drive inverter motor (no belt) and ThinQ Wi-Fi. Front-load door gasket care still applies for odor.
- SpeedLG says clothes come out clean, fresh and dry in as fast as 2 hours, and TurboWash 360 with five jets finishes larger loads in under 30 minutes.
- Heat pump dryerAn Inverter Heat Pump that LG says saves up to 60% energy. Heat pump drying is slower and gentler than a vented dryer, which is normal.
- ezDispenseReservoirs last for 18 to 31 wash cycles per fill.

Exact questions
Questions that only have an answer for the LG WashCombo WM6998HBA
My LG WashCombo isn't drying clothes fully.+
The WashCombo is a ventless heat-pump dryer, so 'not drying' is almost always a maintenance issue in that system, not a broken heater. Clean the lint filter every load and clean the condenser/heat-exchanger and its drain per the manual — a clogged filter or condenser is the top cause. Also avoid overloading (drying needs room to tumble) and remember heat-pump drying runs at lower heat, so it legitimately takes longer than a vented dryer.
