Checking this washer? The Frigidaire ELFW7337*** uses 470 kWh a year with an electric water heater and electric dryer, and 4,154 gallons at DOE's test use. Its IMEF, the cubic feet of laundry washed per kilowatt-hour, dryer included, is 2.76, equal to the class median of 2.76.
Energy and water per year
470 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: 50 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.
4,154 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.

The 470 kWh figure covers the washer, its electrically heated water, and an electric dryer. This site computed it, not the registry, so the figure is a model and not a metered reading. The inputs are the registry's IMEF of 2.76 and its capacity, the drum's volume in cubic feet, of 4.4. Both are applied at DOE's test use. Of the total, 50 kWh is the machine and its electrically heated water alone, as ENERGY STAR files it. The dryer is not in that smaller figure, so the remainder of 470 kWh is the dryer's share. The method is explained in how the yearly figures are calculated, and the source is DOE CCD, retrieved 2026-10-25.
Read the rest
The 4,154 gallons figure is also computed by this site. It starts from the registry's IWF, the gallons of water used per cycle for each cubic foot of drum, which is 3.2. That value is combined with the capacity of 4.4 and applied at DOE's test use. A cost for this water is not stated, because no free national source publishes local water and sewer rates. The page does not estimate one. Real yearly water depends on how often the machine runs, and that frequency is not available here. The figure is a modeled total, not a measurement of one unit in a home.
Among the 360 models registered as front-loading, standard size, the median IMEF is 2.76. This model's IMEF of 2.76 equals that median, so there is no gap between them. The installed price appears in its own block with its source and date, as a modeled range and not a quote. The yearly running cost is not in this text. It depends on the reader's own utility electricity tariff, so the page computes it from the ZIP the reader enters. No cost figure is estimated here, and other models are listed under all clothes washer pages.
