- WA51DG5505A*
If you are verifying the Samsung WA51DG5505A*, it uses 730 kWh a year with an electric water heater and an electric dryer. At DOE's test use it also takes 6,469 gallons of water a year. Its IMEF, the cubic feet of laundry washed per kilowatt-hour, dryer included, is 2.06, the 37th highest of 870 standard-size top-loaders.
Energy and water per year
730 kWh a year with an electric water heater and an electric dryer
Computed by this site from the registry's IMEF and drum capacity at DOE's test use of 295 cycles a year. IMEF counts the washer, heating its water electrically, and the electric dryer's work on what the spin leaves wet — so this is the total for that kind of home. How it is calculated
The machine and its hot water alone, dryer not included: 120 kWh a year, as ENERGY STAR files it.
Not published: A home with a gas water heater, a gas dryer or line drying
DOE's rating assumes electric water heating and an electric dryer and files no split between the machine, the water heating and the drying.
Such a home uses less electricity than the total above; how much less, no registry says for this model.
6,469 gallons of water a year
Computed from the registry's IWF and drum capacity at the same 295 cycles a year.
Not published: What the water costs
water and sewer rates are set by thousands of local utilities and no free national source publishes them.
The gallons above are the figure to multiply by your own water and sewer rate.
This model is rated above the federal minimum IMEF for its class.

This site calculated the 730 kWh figure from DOE CCD data retrieved 2026-10-25. The registry does not publish it directly. The calculation uses the registry's IMEF and the model's capacity, the drum's volume in cubic feet, which is 5.1 here, so the dryer's energy is included. ENERGY STAR files a separate machine-only figure of 120 kWh a year for this model. That figure covers the washer and its electrically heated water alone, with the dryer left out. The gap between 730 kWh and 120 kWh is therefore the dryer's share under the test assumptions. The method behind the yearly energy and water figures sets out the test-use assumptions.
The 6,469 gallons a year comes from the model's IWF, the gallons of water used per cycle for each cubic foot of drum. For this washer the IWF is 4.3, applied to its 5.1 cubic feet at DOE's yearly test use. This site calculated the yearly total, as with the energy figure, because the registry does not publish one. The page gives no cost for that water, since no free national source publishes local water and sewer rates. A plumber or homeowner can apply their own local water and sewer rate to 6,469 gallons directly.

The 870 models registered as top-loading, standard size have a median IMEF of 1.57. This model's 2.06 sits above that median and ranks 37th highest in the class. It is rated above the federal minimum IMEF for its class, while 652 of the 870 models sit at that minimum. A higher IMEF means more cubic feet washed per kilowatt-hour under the test. The running cost does not appear in this text because it depends on your own utility's electricity tariff. Instead, the page calculates it from the ZIP you enter, and other models are listed on all clothes washer pages. The installed price range has its own block with its source and date, as a modeled range rather than a quote.
