- WT7050C*
Checking this washer's registry figures? The LG WT7050C* uses 644 kWh of electricity a year at DOE's test use, with an electric water heater and an electric dryer. It uses 5,708 gallons of water a year. Its IMEF, the cubic feet of laundry washed per kilowatt-hour, dryer included, is 2.06, above the median of 1.57 for standard-size top-loaders.
Energy and water per year
644 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: 180 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.
5,708 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.

This site computes the 644 kWh figure; the registry does not publish it. The inputs are the registry's IMEF of 2.06 and the capacity, the drum's volume in cubic feet, of 4.5, both from DOE's Compliance Certification Database (CCD), retrieved 2026-10-25. The calculation uses DOE's test use. That total covers the washer, an electric water heater and an electric dryer. ENERGY STAR files a separate figure of 180 kWh a year for this model. That figure counts only the machine and its electrically heated water, without the dryer. The difference between the two figures is the dryer's share, and this site does not publish that share as a separate number. A home with a gas water heater or a gas dryer is outside the scope of the 644 kWh figure. For the method, see how the yearly energy and water figures are calculated.
Read the rest
The 5,708 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 4.3. This site multiplies it by the 4.5 cubic foot drum and by DOE's test use. So the yearly total reflects a test load count, not the reader's own household. A home that runs more loads than DOE's test use will draw more water, and a home that runs fewer will draw less. The page does not show what this water costs. No free national source publishes local water and sewer rates, so any cost figure here would be an estimate. A reader who wants a cost can apply the rate from their own water and sewer bill to the 5,708 gallons figure.
The class used for comparison is the 870 models registered as top-loading, standard size. By IMEF, this model ranks 37th highest of 870. It is rated above the federal minimum IMEF for its class, while 652 models in the same class are rated at that minimum. The rank measures energy efficiency only. The registry data behind it does not cover wash results, noise or service life. The running cost is not stated in this text, because it depends on the reader's own electricity tariff. The page computes it from the reader's ZIP code instead. The installed-cost range appears in its own block, with its source and date, as a modeled range rather than a quote. Other models in this class are listed on the clothes washer model pages.
