- WM3050C*
Checking the LG WM3050C*? With an electric water heater and an electric dryer, this site calculates that it uses 442 kWh and 3,894 gallons of water a year at DOE's test use. Its IMEF, the cubic feet of laundry washed per kilowatt-hour, dryer included, is 2.67. That is below the median of 2.76 for front-loading, standard-size models.
Energy and water per year
442 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.
3,894 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 442 kWh figure covers more than the washer alone. This site calculated it from the registry's IMEF of 2.67 and the model's capacity, the drum's volume in cubic feet, of 4, at DOE's test use. IMEF includes the dryer's energy, so the total assumes an electric dryer and an electric water heater. Only ENERGY STAR publishes the washer's own share, and it lists no matching rating for this model. The machine-only figure for the WM3050C* is therefore not available. An installed price range is also not published for the same reason: the cost database's model needs that machine-only figure. The registry source is DOE's Compliance Certification Database, retrieved 2026-10-25. The methodology page explains how the yearly energy and water figures are calculated.
Read the rest
The 3,894 gallons a year comes from the registry's IWF, the gallons of water used per cycle for each cubic foot of drum. For this model the IWF is 3.3. This site multiplied it by the 4 cubic-foot drum at DOE's test use. So the yearly figure covers the water the washer draws at that test use. It will differ if a household runs more or fewer loads. The page does not show what that water costs. No free national source publishes local water and sewer rates, so a cost figure would have to be an estimate. Anyone checking this model can multiply the gallon figure by their own local water and sewer rate.
The WM3050C* is compared with 360 other models registered as front-loading, standard size. Its IMEF of 2.67 ranks 257th highest of the 360, below the class median of 2.76. It is rated above the federal minimum IMEF for its class. By comparison, 37 models in the class are rated at that minimum. The minimum value itself is not in this page's data. The running cost is not given in the text because it depends on your own electricity tariff. The page calculates it from your ZIP instead. Other models of the same type are listed on all clothes washer pages.
