  • WA48J777*A*

Checking this washer's rated use? With an electric water heater and an electric dryer, the SAMSUNG WA48J777*A* uses 618 kWh a year at DOE's test use. Water use at that test use is 5,522 gallons a year. Its IMEF, the cubic feet of laundry washed per kilowatt-hour, dryer included, is 2.29, above its class median of 1.57.


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.

What these figures mean

The 618 kWh figure covers more than the washer itself. This site calculated it, not the registry. It uses the registry's IMEF of 2.29 and the capacity, the drum's volume in cubic feet, of 4.8, at DOE's test use. IMEF includes the dryer's energy, so the figure assumes an electric water heater and an electric dryer. The registry values come from DOE's Compliance Certification Database, retrieved 2026-10-25. The machine's own share is not available for this model. DOE's database files only IMEF. ENERGY STAR is the one source that gives the machine's share separately, and it lists no matching rating for the WA48J777*A*. The method is set out in how the yearly energy and water figures are calculated.

Read the rest

The 5,522 gallons a year comes from the WA48J777*A*'s IWF, the gallons of water used per cycle for each cubic foot of drum, of 3.9. This site multiplied that factor by the 4.8 cubic-foot capacity and by DOE's yearly cycle count at test use. A lower IWF means fewer gallons per cubic foot each cycle. The cost of that water is not shown on this page. No free national source publishes local water and sewer rates, so the page gives the volume only. Any washer with a figure worked out the same way rests on the same test use. Their yearly gallons can be compared directly without that cost.

Among the 870 models registered as top-loading, standard size, the WA48J777*A* has the 28th highest IMEF. Its IMEF of 2.29 is above the class median of 1.57 and above the federal minimum for the class. Of those 870 models, 652 are rated at that federal minimum. The rank compares registered ratings only; it does not show how the washer performs in a given home. The running cost is not given in this text. It depends on the reader's own electricity tariff, so the page works it out from the reader's ZIP code. The installed price range is also not available. It needs the machine-only figure described above, which ENERGY STAR has not filed for this model. Other washers are covered on all clothes washer pages.
