For a second opinion: the Maytag H18vB942(3B) uses 485 kWh a year at DOE's test use, with an electric water heater and electric dryer. At the same test use, it takes 4,531 gallons of water a year. Its IMEF, the cubic feet of laundry washed per kilowatt-hour, dryer included, is 2.92, above its class median of 2.76.
Energy and water per year
485 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.
4,531 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 485 kWh figure is computed by this site, not filed by the registry. It combines the model's IMEF of 2.92 with its capacity, the drum's volume in cubic feet, of 4.8. The calculation uses the yearly cycle count set in DOE's test procedure, and the inputs come from DOE's Compliance Certification Database, retrieved 2026-10-25. Because IMEF folds in the dryer, that yearly figure covers the washer and the dryer's share together. A figure for the washer alone is not available here. Only ENERGY STAR splits the machine's own energy out, and it lists no matching rating for this model. The page on how the yearly energy and water figures are calculated sets out each step.

The water figure is built on IWF, the gallons of water used per cycle for each cubic foot of drum. This model's IWF is 3.2, and this site multiplies it by the capacity and DOE's yearly cycle count. The result, 4,531 gallons a year, is a volume at test use, not a forecast for any one household. No cost for that water is shown on this page. No free national source publishes local water and sewer rates, so any cost figure would be an estimate. The registry record behind these figures lists the model as sold under MHW6630H**.
This model is compared with the 360 models registered as front-loading washers of standard size. Its IMEF of 2.92 ranks 33rd highest of the 360. In the same class, 37 models sit at the federal minimum IMEF; this one is rated above it. A higher IMEF means more laundry washed per kilowatt-hour, so the rank reflects efficiency at test use only. The yearly running cost is not stated in this text, because it depends on your own utility's electricity tariff. The page computes that cost from the ZIP you enter. An installed price range is also not published, because the cost database needs the machine-only energy that is unavailable here. Other front-loading models can be checked through the index of all clothes washer pages.
