Offering the highest efficiency for their price point, according to the maker, Whirlpool Gold Series dishwashers use nearly half the water and energy compared to dishwashers manufactured as recently as 2006. The dishwasher’s micro-filter wash system has been optimized to minimize flow restrictions, which allows more water to reach the dishes. The filtration system also removes micro-particles from the wash, so the water can be used for a longer period of time without soils redepositing on the dishes, and the upper and lower spray arms can run independently during a cycle for more effective water coverage while using less water. Beyond that, an overall smaller volume of water needed for the cycle means there’s less water to heat, making the unit more energy-efficient. Whirlpool | 800.253.3977 |
