- WT6485C*
For anyone checking the LG WT6485C*, it uses 846 kWh a year with an electric water heater and an electric dryer. It uses 8,629 gallons of water a year at the same DOE test use. Its IMEF, the cubic feet of laundry washed per kilowatt-hour, dryer included, is 1.57, the same as its class median.
Energy and water per year
846 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.
8,629 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.

The 846 kWh figure for the WT6485C* assumes an electric water heater and an electric dryer, so it is not the washer's draw alone. This site computed it from the registry's IMEF of 1.57 and its capacity, the drum's volume in cubic feet, at DOE's yearly test use. That capacity is 4.5, and the registry data come from DOE's CCD as retrieved on 2026-10-25. Because IMEF folds the dryer in, part of the 846 kWh total belongs to drying the load rather than washing it. A machine-only figure would show the washer's share alone, but DOE's database does not publish one; only ENERGY STAR splits the machine out. ENERGY STAR lists the WT6485C* under no matching rating, so its machine-only energy is not available on this page.
Read the rest
For this model, IWF, the gallons of water used per cycle for each cubic foot of drum, is 6.5. This site combined that IWF with the 4.5 capacity at DOE's yearly test use to reach 8,629 gallons a year. The page on how the yearly energy and water figures are calculated sets out both steps. No water cost is shown beside the 8,629 gallons total, and none is estimated here. No free national source publishes local water and sewer rates, so that cost is not available for this model. The gallons figure itself rests only on the registered IWF and capacity, so it does not change with local rates.
The WT6485C* is compared with the 870 models registered as top-loading, standard size, whose median IMEF is 1.57. Its own IMEF of 1.57 matches that median and sits exactly at the federal minimum for the class. Of the 870 models, 652 are rated at that same minimum, so this page claims no rank inside the tie. The running cost is not stated in the text, because it depends on the reader's own utility electricity tariff. The page computes that cost from the reader's ZIP rather than estimating a figure for this model. An installed price range is not published, because the cost database needs the machine-only energy that is unavailable for this model. Other models in the same class can be checked through all clothes washer pages.
