  • WA45M70**A*

Checking the SAMSUNG WA45M70**A*? At DOE's test use, it takes 644 kWh a year with an electric water heater and an electric dryer, and 5,708 gallons of water. Its IMEF, the cubic feet of laundry washed per kilowatt-hour, dryer included, is 2.06, above its class median of 1.57.


Energy and water per year

644 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.

5,708 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.

No CPSC recall names this model.

Checked against the CPSC recall database. CPSC does not publish a model-level match for this product category, so this list is curated by hand from the manufacturer's recall filings.

What these figures mean

The 644 kWh figure is computed by this site, not filed by the registry. It combines the registry's IMEF of 2.06 with the model's capacity, the drum's volume in cubic feet, which is 4.5. The result is scaled to DOE's test use for one year. Because IMEF folds the dryer in, the total covers the washer, an electric water heater and an electric dryer together. A figure for the machine alone is not available for this model. DOE's database does not split it out; only ENERGY STAR does, and it lists no matching rating for the WA45M70**A*. For the same reason, no installed price range is published here, since the cost database needs that machine-only figure. The source is DOE's database, retrieved 2026-10-25. The steps are set out in how the yearly energy and water figures are calculated.

Read the rest

The 5,708 gallons yearly figure comes from the registry's IWF, the gallons of water used per cycle for each cubic foot of drum. This model's IWF is 4.3. This site multiplies it by the 4.5 cubic-foot drum at DOE's test use. Because IWF is set per cubic foot, a larger drum at the same IWF draws more water in a year. A household running more or fewer cycles than the test assumes will see a different total. The cost of the 5,708 gallons is not stated. No free national source publishes local water and sewer rates, so the page does not estimate a charge. That cost depends on the reader's local utility, which this registry data does not cover.

Among the 870 models registered as top-loading, standard size, the WA45M70**A* ranks 37th highest by IMEF. Its 2.06 sits above the 1.57 median and above the federal minimum IMEF for its class. In the same class, 652 models are rated at the federal minimum. A higher IMEF means more laundry washed per kilowatt-hour under the test. The rank compares rated IMEF only; it does not cover water use, price or anything outside the registry. The running cost is not stated in this text, because it depends on the reader's own electricity tariff. The page computes it from the reader's ZIP instead. Other models in the class are listed under all clothes washer pages.
