- WA40A3005A*
If you are checking the Samsung WA40A3005A*'s registry figures, it uses 752 kWh a year with an electric water heater and an electric dryer, at DOE's test use. Its water use is 7,670 gallons a year. Its IMEF, the cubic feet of laundry washed per kilowatt-hour, dryer included, is 1.57, equal to its class median.
Energy and water per year
752 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.
7,670 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 exactly at the federal minimum IMEF for its class, like many others; no rank is claimed inside that tie.
What you can do. Federal minimum means this model uses as much energy as the law allows for its class. 218 washers in the same class file a higher IMEF; at the same drum size and use, a higher IMEF is less energy a year. See the most efficient washers in each 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 calculates the 752 kWh figure; the registry does not file it. The calculation takes the registry's IMEF of 1.57 and the washer's capacity, the drum's volume in cubic feet, of 4. It applies them to the number of cycles a year that DOE's test procedure assumes. IMEF folds the dryer in, so the figure covers the washer, an electric water heater and an electric dryer together. It is not the machine's own share. DOE's database files only IMEF, and only ENERGY STAR splits the machine out. ENERGY STAR lists the WA40A3005A* under no matching rating, so this washer's own yearly energy is not available. The steps are set out in how the yearly energy and water figures are calculated. The source data came from DOE's Compliance Certification Database, retrieved on 2026-10-25.

The 7,670 gallons figure is also this site's calculation. It uses the registry's IWF, the gallons of water used per cycle for each cubic foot of drum. For this model the IWF is 6.5. The calculation combines it with the capacity of 4 cubic feet and the same yearly cycle count used for energy. The result describes DOE's test use, not the loads a particular household runs. A household that runs more or fewer loads than the test assumes will use a different amount. The page does not show what that water costs. No free national source publishes local water and sewer rates, so no amount is stated or estimated. That cost is set by the reader's own local water and sewer utility.
DOE's registry lists 870 models as top-loading, standard size, and their median IMEF is 1.57. This model's 1.57 matches that median and is rated exactly at the federal minimum for the class. 652 of the 870 models share that minimum rating, so the page claims no rank inside the tie. A higher IMEF would mean more laundry washed per kilowatt-hour. This model's rating is at the minimum, not above it. The installed price range is not published. The cost database's model needs the washer's own yearly energy, and ENERGY STAR has not filed one for the WA40A3005A*. The running cost of the 752 kWh depends on the reader's own utility electricity tariff. The page works it out from the reader's ZIP instead of stating it in the text. Other models are listed on all clothes washer pages.
