DESC: As an ENERGY STAR Partner, GE has determined that this dishwasher meets the Energy Star guidelines for energy efficiency for year-round energy and money savings. A highly sensitive sensor measures soil levels and water temperature. It then determines the length of the cycle, controls the water temperature and adjusts the number of water fills. The Steam Pre-Wash option helps loosen tough soils before any cycle. After the second pre-wash fill, the dishwasher stops the water circulation and activates the calrod heater. Water dripping from the glassware and dishware falls onto the calrod heater and creates a wall of steam to help loosen soils before the main wash.
