Dishwasher Reviews

As with the Clothes Washer, the Dish Washer uses hot water and that is the big cost. Our house is super insulated and the water is solar heated so we save a lot more money then the normal home owner.

1. High Energy Factor
ACEEE recommends that you consider dishwashers that have an Energy Factor (EF) of at least 0.65, or an estimated energy use of less than 340 kWh/year. This is about 40% better than the federal standard. You can find which products meet this requirement on the showroom floor by looking on the yellow EnergyGuide label on each product.

Energy Factor measures the number of cycles that can be run with 1 kWh of electricity, and, unlike clothes washer efficiency ratings, does not take into account water use; although high-efficiency models are more likely to incorporate improvements to the spray arm, sump geometry, and/or pump design to reduce water requirements per cycle.

2. Low Water Use
To find the most water-efficient models, you must look beyond ENERGY STAR and EnergyGuide. Some ENERGY STAR models use half as much water as others, saving hundreds of gallons of water each year. Check the manufacturer’s literature or contact your local water utility. In some states, electric and water utilities offer rebates for the purchase of models that are exceptionally efficient.

3. Wash Cycle Options
Most dishwashers have several different wash cycle selections. The more options you have, the better you can tailor the energy and water use needed for a particular load. Look at the manufacturer’s literature for total water use with different cycles.Some dishwashers on the market today use “soil sensor” technology to automatically adjust water use depending on how dirty the dishes are in each load. There are highly-efficient dishwashers with and without this feature.4. Energy-Saving “No-Heat” Dry
An electric heating element is generally used to dry dishes at the end of the final rinse cycle, consuming about 7% of dishwasher energy use. Most new dishwashers offer an energy-saving no-heat drying feature. At the end of the rinse cycle, if the feature is selected, room air is circulated through the dishwasher by fans, rather than using an electric heating element to bake the dishes dry.
