- WA48J770*A*
Checking the SAMSUNG WA48J770*A*? At DOE's test use, this top-loading washer uses 618 kWh of electricity a year with an electric water heater and an electric dryer. It uses 5,522 gallons of water a year. Its IMEF, the cubic feet of laundry washed per kilowatt-hour, dryer included, is 2.29, which ranks 28th highest of 870 standard-size top-loaders.
Energy and water per year
618 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
Not published: The washer's own share, without the dryer
DOE's database files IMEF, which folds the dryer in; only ENERGY STAR splits the machine out, and it lists this model under no matching rating.
The total above, and the IMEF it comes from, stand as filed.
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.
5,522 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.

Installed cost and service life
Not published: Installed cost range
NLR REMDB's cost model needs the washer's own yearly energy use, which only ENERGY STAR files — and it lists no matching rating for this model.
Ask retailers or installers for a written quote that names this model number. The yearly energy, water and running cost on this page do not depend on it.
Service life: DOE’s cost database assumes 11 years for top-loading washers. That is a class assumption, not this model’s rating or a warranty — no registry publishes either.

This site calculated the 618 kWh figure; the registry does not publish it. It uses the registry's IMEF of 2.29 and the capacity, the drum's volume in cubic feet, of 4.8 cubic feet, at DOE's yearly test use. The inputs come from DOE CCD data retrieved 2026-10-25. IMEF folds the dryer in, so the figure covers the washer, the electric water heater and the electric dryer together. A machine-only figure, meaning the washer's own share of that total, is not available for this model. Only ENERGY STAR splits the machine out, and it lists the WA48J770*A* under no matching rating. For the same reason no installed price range is published here, because the cost database needs the washer's own yearly energy. The steps are set out in how the yearly energy and water figures are calculated.
Read the rest
The 5,522 gallons a year comes from the registry's IWF, the gallons of water used per cycle for each cubic foot of drum. For this model the IWF is 3.9. This site multiplies it by the 4.8 cubic foot capacity and by DOE's yearly test cycles. The result is a gallon count at test use, not a measured household total. A home that runs more or fewer loads than the test assumes will use a different amount. The cost of that water is not shown. No free national source publishes local water and sewer rates, so the page gives no estimate. Anyone checking a bill can apply the local utility's own water and sewer rates to the 5,522 gallons figure.
Among the 870 models registered as top-loading, standard size, the median IMEF is 1.57. This model's IMEF of 2.29 sits above that median and above the federal minimum IMEF for its class. It ranks 28th highest IMEF of 870. For comparison, 652 models in the same class are rated at the federal minimum. A higher IMEF means more cubic feet washed per kilowatt-hour, so the rank reflects the test rating only. The yearly running cost does not appear in this text, because it depends on the reader's own electricity tariff. The page calculates it from the reader's ZIP instead.
