The highest-rated washer/dryer combo is the LG WM3477HW, according to ConsumerSearch in August 2014. Positive aspects of this combo are the lack of venting necessary, its small size, its washing ability and its array of features. Possible downfalls are the price and dryer performance that is average.
The LG WM3477HW appears similar to a front-load washer. Basic washer connections such as a water supply, drain and 120-volt line are needed, but no ventilation connections are necessary. Features include a moisture sensor, SmartDiagnosis that allows remote maintenance support by LG technicians, and a nine-wash programming cycle. The dryer has four sensor cycles and three manual choices for timed drying. The basket is stainless steel.
