Saving Energy with Dishwashers

Several manufacturers of home appliances the world over are investing significantly into providing customers with energy saving models. Selecting an energy efficient dishwasher could lower power bills substantially.

Using an energy efficient dishwasher offers the dual benefit of lowering energy bills and protecting the environment. Contrary to popular belief, dishwashers consume less energy and water than when dishes are washed with hands, provided these appliances are operated on full load and are certified as energy efficient.

To further energy saving, several national and international agencies have launched programs with an aim to certify home appliances as energy saving ones, if they meet the requisite criteria. US-based Energy Star, which is a program that is jointly managed by the US Environmental Protection Agency and the US Department of Energy, claims that dishwashers that are certified by the agency could use at least 41% lower energy than the federal minimum standard for energy consumption. An energy-saving dishwasher could reduce power bills by $30 per year, as compared to those manufactured before the mid-1990s.

Moreover, these dishwashers use much less water than their conventional counterparts. According to a recent article by customerreports.org, some dishwashers use as much as ten gallons of water per load, while the Asko Encore 3531XLHD uses three gallons and the Kenmore 1312[2] and the Bosch SHE33MO[2]UC use five gallons each. Jenn-Air’s JDB1105AW and Maytag’s MDB8951BW are associated with electricity bills of about $105 a year, Asko Encore relates to a power tab of about $52 per annum.

Similarly, Energy Saving Trust, which is jointly funded by the British Government and the business community, says that if everyone in the UK replaces their old dishwasher with one that is certified by the Trust, the country could save £79 million per year.

Some energy saving tips:

 

  • Run dishwasher on full load.
  • Turn off the appliance instead of leaving it on standby while it is not in use.
  • Avoid using features such as heat-dry, rinse-hold and pre-rinse.
  • Lower the water-heater thermostat in dishwashers that have booster heaters.
