If you are checking the LG WT1501C*, it uses 558 kWh a year with an electric water heater and an electric dryer at DOE's test use. Its water use is 4,912 gallons a year. Its IMEF, the cubic feet of laundry washed per kilowatt-hour, dryer included, is 2.38, above the class median of 1.57.
Energy and water per year
558 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: 140 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.
4,912 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.

The 558 kWh figure covers the washer, an electric water heater and an electric dryer together. This site computed it, not the registry. It uses the registry's IMEF of 2.38 and capacity, the drum's volume in cubic feet, of 4.5 at DOE's test use. The inputs come from the DOE CCD, retrieved 2026-10-25. ENERGY STAR files a separate machine-only figure of 140 kWh a year. That covers the machine and its electrically heated water alone, with the dryer not included. The dryer is the difference in scope between the two figures. The registry records this model as sold as WT1150C*. The steps behind both yearly figures are set out in the method for the yearly energy and water figures.

This site also computed the 4,912 gallons yearly water figure. It uses the registry's IWF, the gallons of water used per cycle for each cubic foot of drum. This model's IWF is 3.7, applied to its 4.5 cubic foot drum at DOE's test use. IWF times capacity gives the gallons per test cycle, and the yearly total follows from the test cycle count. Actual use depends on how often the machine runs, which the registry does not record. The water cost is not stated here. No free national source publishes local water and sewer rates, so any cost figure would be an estimate.
This model is compared with the 870 models registered as top-loading washers of standard size. Their median IMEF is 1.57, and this model's 2.38 is above that median. It has the 10th highest IMEF of the 870. In the class, 652 models sit at the federal minimum IMEF, and this model is rated above that minimum. The rank reflects IMEF only and does not cover IWF or price. The installed-cost range appears in its own block on this page, with its source and date. The running cost is not given in this text. It depends on your own electricity tariff, so the page computes it from your ZIP. Pages for other washers are listed under all clothes washer pages.
