Dishwasher
- Low water usage dishwashers built since mid-1994 use seven to 10 gallons per cycle. Choose the lowest usage practical for your needs.
- Low wattage fans on newer models replace heaters to dry dishes and are much more energy efficient.
- Air dry controls eliminate the heat drying cycle. These save up to 30 percent of the energy normally used.
- Short cycle selections use less hot water and can save up to 25 percent of the water heating costs.
- Water heater boosters heat water before washing with it. The water heater can be set at 120 degrees and the booster will heat the preheated water up to 140 - 145 degrees. That can save as much as 18 percent on your water heating bill.
- Wash full loads of dishes, but don’t overload.
- Allow dishes to air dry if the unit has an energy saver dry cycle.
- Use short cycles whenever possible, but not the rinse-hold cycle.
- Use the rinse-hold feature as little as possible. This feature uses three to seven gallons of hot water.
- Use the proper amount and type of detergent. Insufficient cleaning and even damage to the unit can occur if the wrong type of detergent is used.
- Store powdered dishwasher detergent in a cool, dry place. It can cake and become stale over time.
- Try to run the dishwasher during the coolest part of the day during the summer months.
- Rinse dishes in cool water if you must rinse before placing them in the unit. Refer to your owner’s manual; most newer models say pre-rinsing is unnecessary.
- Keep filters and drains clean.
- Avoid placing the dishwasher next to the refrigerator. The heat and moisture from the dishwasher cause the refrigerator to run less efficiently and use more energy.
