Dishwashers: Buyer’s Guide
Your new dishwasher’s best feature is its water efficiency, which helps to reduce your water consumption and the cost to heat water. The EnergyGuide label and other guidelines below will help you find the right dishwasher for you.
Look for the Label: EnergyGuide
Most major appliances, electronics, and lighting must meet specific energy standards outlined by the U.S. Department of Energy. Energy use and efficiency are displayed on the yellow EnergyGuide label, which compares the estimated annual operating cost with similar models and states how much energy the appliance is expected to use annually. The EnergyGuide label will also display the ENERGY STAR® logo, if the particular model qualifies.
You’ll see an estimated yearly operating cost on a scale showing a range for similar models. The amount is based on the national average rate for electricity. Look for models with the lowest operating costs.
You’ll also find the estimated annual energy consumption for this model based on typical use. Multiply this by your local electricity rate to get a better estimate of your actual operating cost.
Look for the Logo: ENERGY STAR®
- Standard size washers use less than 324 kWh/year and 5.8 gallons/cycle
- Compact size washers use less than 234 kWh/year and 4 gallons/cycle
Using a full-sized dishwasher less often—only when full—can be more efficient than running a compact machine too often. On the other hand, an energy-saving compact model might better meet your needs if you do not dirty a lot of dishes.
Models of Efficiency
The most efficient dishwashers use about 5 gallons of water per load in light or energy-saving modes, compared to 11 gallons or more for conventional dishwashers.
EF: The Energy Factor
A higher Energy Factor (EF) number indicates a more efficient machine. The American Council for an Energy-Efficient Economy recommends an EF of at least 0.65 for dishwashers.
Cycles: Save Even More
Consider choosing a dishwasher with cycle options. Lightly soiled loads can run on the energy saver cycle, and “No-Heat” dry cycles can save even more by using room air—rather than heated air—to dry your dishes.
