WM3555HWA is a compact, 2.4 cu. ft. version of LG’s all-in-one washer/dryer, sized for an apartment or closet installation rather than a full laundry room. It uses the same single-drum, heat-pump principle as LG’s larger WashCombo units — wash and dry happen in the same drum without the load being moved — just at a smaller capacity that suits a smaller footprint.
Because the drum is smaller, an unbalanced load shows up as a UE fault more readily than it would on a full-size machine, simply because there’s less drum volume to absorb an unevenly distributed wash load before the spin cycle detects it. That’s worth ruling out with a smaller, better-distributed load before assuming a suspension or bearing fault.

- 2.4 cu. ft. front-load all-in-one washer/dryer
