WM3499HVA is another compact all-in-one washer/dryer in LG’s line, close in capacity to the WM3488HW and WM3555HWA but sold as its own model number — the kind of near-identical sibling models common in appliance lineups, where a small spec or finish change earns a new number rather than a variant letter. All three share the same core mechanism: a single drum, heat-pump drying, and no external vent.
Because there’s no vent to inspect, the internal condenser is the single most useful thing to check on any of these compact combo units when drying performance drops off gradually rather than failing outright — lint that would normally collect in a vent duct instead collects inside the condenser path, and clearing it is a very different job from a dryer belt or heating element repair.
