If you are checking the LG WT7700H*A, this top-loading washer uses 609 kWh a year at DOE's test use. That assumes an electric water heater and an electric dryer. It uses 5,381 gallons of water a year. Its IMEF, the cubic feet of laundry washed per kilowatt-hour, dryer included, is the 1st highest of 870 in its class.
Energy and water per year
609 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
The machine and its hot water alone, dryer not included: 150 kWh a year, as ENERGY STAR files it.
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.
5,381 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
This model's drum size lies outside the range NLR REMDB's cost model was fitted on, and the range is not stretched past it.
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.

The 609 kWh figure includes the energy an electric dryer uses on the washed load, with an electric water heater heating the wash water. The registry does not publish this figure. This site computed it from the registry's IMEF of 2.76 and its capacity, the drum's volume in cubic feet, of 5.7. The inputs come from the DOE Compliance Certification Database, retrieved 2026-10-25. ENERGY STAR files a separate figure of 150 kWh a year for the machine and its electrically heated water alone. That figure leaves the dryer out, so it is the one to set against a washer-only claim. Both figures assume DOE's test use, not a household's own number of loads. The steps are set out in how the yearly energy and water figures are calculated.
Read the rest
The 5,381 gallons figure is also this site's calculation. It starts from the registry's IWF, the gallons of water used per cycle for each cubic foot of drum, of 3.2. That factor is scaled by the 5.7 cubic foot drum at DOE's test use. A household that runs more or fewer loads than the test assumes will see a different yearly total. The page states no cost for this water. No free national source publishes local water and sewer rates, so any cost figure would be an estimate. The registry also lists this model as sold under the number WT7710H*A. A label showing that number can be checked against the same ratings on this page.
The comparison class is the 870 models registered as top-loading washers of standard size. Their median IMEF is 1.57, and this model's 2.76 sits above that median. It is rated above the federal minimum IMEF for its class, while 652 of the 870 models are rated at that minimum. By IMEF, it ranks 1st highest of 870. The running cost is not given in this text because it depends on your own utility electricity tariff. The page computes it from your ZIP code instead. An installed price range is not published either. This model's ratings lie outside the range the cost database's model was fitted on, and that range is not stretched to cover it. Other models are listed on the full list of clothes washer pages.
