There is a debate as to whether washing dishes by hand or using a dishwasher saves more money. This is because different studies have come to different conclusions in support of each. The issue that matters and will tell you which is more efficient for you is the way that you typically wash dishes when you do so by hand.
Some studies have shown that using a dishwasher requires about one-third less water than when washing dishes by hand. Other studies have shown, however, that if you fill the wash and rinse basins instead of letting the water run when washing dishes by hand, you'll use about half as much water as a dishwasher.
Therefore, if you use running water when washing by hand, the dishwasher is probably more efficient while if you wash dishes by filling the sink tubs, washing by hand is more energy efficient.
How To Save Money On Your Dishwasher:
1) Run the dishwasher only when it is full. A typical dishwasher costs about $60 to $100 a year to run with 80% of the cost due to heating the water needed for it. Running a partially filled dishwasher two times will use twice as much energy as running a full load once since dishwashers don't have different load size settings.
2) Purchase a dishwasher that requires less hot water. Dishwashers differ in the amount of hot water used in the wash cycle. The manufacturer's specifications or the Energy Guide label should list this information.
3) Check to see if your purchase of an energy efficient dishwasher will qualify for a state tax credit. Some states offer tax credits on your personal income tax when you purchase an energy-efficient dishwasher model.

4) Do not install your dishwasher next to your refrigerator. The heat and moisture given off by the dishwasher will increase the refrigerator's energy consumption. If you must put them next to each other, place a sheet of foam between them for insulation.
5) If your dishwasher has an "economy" or "energy saving" setting, use it.
6) If you have a choice between an "air-dry" and "heat-dry" setting on your dishwasher, choose the air dry setting. It will use 15% to 50% less energy than the heat-dry setting.
7) Turn your dishwasher off after the final rinse and open the door. It will take some time for the dishes to dry, but they will dry without using any energy.
8) If your dishwasher has a "rinse hold" setting, you want to avoid this option. This rinse hold setting typically uses an extra 3 to 7 gallons of hot water for each wash.
9) Choose the shortest wash cycle on your dishwasher. A short cycle uses less energy and will work just as well on everything but the dirtiest of dishes.
10) Although many newer dishwashers do not require you to rinse dishes off before loading, many people still do. If you prefer to pre-rinse your dishes, use cold water to do so.
