WKHC152HWA is a heat-pump WashTower — the washer half is a standard LG front-load machine, but the dryer half is ventless, using the same internal heat-pump-and-condenser principle as LG’s WashCombo units rather than a resistive element and an external duct. That makes it a genuine hybrid: two-machine WashTower diagnostics on the washer side, and single-drum-style heat-pump diagnostics on the dryer side.
Because there is no external vent to inspect on the dryer half, a slow or incomplete dry cycle on this model is a condenser question, not a duct-blockage question — the same troubleshooting logic that applies to LG’s WashCombo line applies here, just on one half of a WashTower rather than a single shared drum.
Key Features
- Single-cabinet WashTower with a heat-pump ventless dryer half
- Single control panel governing both machines
- No external vent required for the dryer half
- Standard-capacity heat-pump tier
Most Common Issues on This Model
dHE-style heat-pump fault isolated to the dryer half
OE drain fault isolated to the washer half
Dry cycle slowing as the internal condenser collects lint
Shared control panel fault
