- WM3370H*A
If you are checking this washer's registry figures, the LG WM3370H*A uses 460 kWh a year at DOE's test use. That assumes an electric water heater and an electric dryer, and water use comes to 4,059 gallons a year. Its IMEF, the cubic feet of laundry washed per kilowatt-hour, dryer included, is 2.76, equal to its class median.
Energy and water per year
460 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.
4,059 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 front-loading washers. That is a class assumption, not this model’s rating or a warranty — no registry publishes either.

The 460 kWh total is computed by this site, not filed by the registry. It applies this model's IMEF of 2.76 and its capacity to DOE's yearly test use. Its capacity, the drum's volume in cubic feet, is 4.3. Because IMEF folds the dryer in, the total covers drying as well as washing and water heating. The machine's own share is not available for this model. DOE's database files only IMEF, and only ENERGY STAR splits the washer out from the dryer. ENERGY STAR lists the WM3370H*A under no matching rating, so no machine-only figure is published here. The DOE data behind the total was retrieved on 2026-10-25. Each step is set out in how the yearly energy and water figures are calculated.
Read the rest
The 4,059 gallons a year comes from this model's IWF, the gallons of water used per cycle for each cubic foot of drum. For the WM3370H*A, the IWF is 3.2. This site multiplies that value by the 4.3 cubic-foot drum and by DOE's yearly test use. The result assumes DOE's test use, not any household's own count of loads. What that water costs is not stated on this page. No free national source publishes local water and sewer rates, so the 4,059 gallons carries no cost figure here. A reader checking a utility bill can set the gallons against that utility's own published rate schedule.
Among the 360 models registered as front-loading, standard size, this model's IMEF of 2.76 equals the class median of 2.76. It holds the 101st highest IMEF of those 360 models. It is rated above the federal minimum IMEF for its class, where 37 models sit at that minimum. The running cost is not given in the text, because it depends on the reader's own electricity tariff. The page computes that cost from the reader's ZIP instead. An installed price range is not published for the WM3370H*A. The cost database needs the washer's own yearly energy, which ENERGY STAR does not list for this model. Other front-loading and top-loading models appear in the index of all clothes washer pages.
