Washing and rinsing dishes by hand three times a day actually uses more hot water and energy than one load a day in an automatic dishwasher. Here are some tips for operating your dishwasher efficiently:
• Run your dishwasher only when it is filled to capacity, but not overloaded. This will cut the costs of energy, water and detergent.
• Use partial-load cycles, rinse-only cycles, mid-cycle turn-offs and other special features designed for better energy use and more convenience.
• Always choose the shortest washing cycle that will clean your dishes, and scrape off heavy food accumulated before loading dishes into the dishwasher.
• Wait to use your dishwasher until night on hot days. You will avoid adding heat in the house during the hottest time of the day.
