I purchased this washer in September of 2012. One week later the belt popped. The repairman came and fixed it, only for it to happen again a few days later. In April 2013 the motherboard needed replaced. All in all we have had 7 service visits. I think it cleans clothes great and spins enough water out so that drying time is cut in half. If it would work all of the time. Energy Efficiency It helps by reducing drying time. Cleaning Time This washer cycles are pretty fast. The spin cycle lasts less time than other washers because it spins at a higher rate of speed. Performance You can always tell when something is messing up because it will stop spinning water out of the clothes Ease of Use It is real easy to use. It even has a balance sensor. Design Great design but the cycle setting knob is flimsy. Durability Seven service calls in a year is too much. One replaced motherboard, one replaced motor, and five belts replaced. This was with only two loads a week.
