GE. Profile series SmartDispense full-size washers and dryers achieve an MEF rating of 2.23 and a WF of 4.0 (24% and 87.5% better than 2009 thresholds, respectively) and feature steam technology. The 4.2-cubic-foot-capacity, stainless steel–tub washer automatically senses the load and adjusts the water level to as little as 10 gallons per load; a spin cycle up to 1,300 rpm reduces the energy load on the dryer. The units communicate to match load settings. 800.626.2005. www.geappliances.com.
