- WM6700H*A
For anyone checking the LG WM6700H*A: this front-loading washer uses 476 kWh of electricity a year at DOE's test use, with an electric water heater and an electric dryer. It uses 4,425 gallons of water a year. Its IMEF, the cubic feet of laundry washed per kilowatt-hour, dryer included, is 3.1, above its class median of 2.76.
Energy and water per year
476 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: 105 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.
4,425 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 476 kWh figure is calculated by this site, not taken from the registry. It combines the registry's IMEF of 3.1 with the model's capacity, the drum's volume in cubic feet, of 5 cubic feet at DOE's yearly test use. The total assumes an electric water heater and includes the energy an electric dryer uses on the washed laundry. ENERGY STAR files a separate machine-only figure of 105 kWh a year for this model. That figure covers the washer and its electrically heated water alone, with the dryer left out. The two figures differ because only the first one includes the dryer. The registry values come from the DOE Compliance Certification Database, retrieved 2026-10-25. The method behind the yearly energy and water figures sets out each step.
Read the rest
The 4,425 gallons yearly water figure is also this site's calculation, not a registry value. It multiplies the registry's IWF, the gallons of water used per cycle for each cubic foot of drum, of 3 by the 5 cubic-foot capacity. It then applies DOE's yearly test use, the same basis as the energy figure. The page gives no water cost for 4,425 gallons. No free national source publishes local water and sewer rates, so any cost here would be an estimate. A reader who knows the local water and sewer rate can apply it to this figure directly. The text also gives no electricity running cost for 476 kWh. That cost depends on the reader's own utility tariff, so the page works it out separately from the reader's ZIP code.
For class comparison, the model is set against the 360 models registered as front-loading, standard size. By IMEF, it ranks 5th highest of those 360 models. The class median IMEF is 2.76, and this model's 3.1 is above it. It is also rated above the federal minimum IMEF for its class. In the same class, 37 models are rated at that federal minimum. This rank covers IMEF at DOE's test use only. It does not rank water use, price or any other measure. The installed-price range on this page appears in its own block, with its source and date. It is a modeled installed-cost range, not a quote. Other registered models appear on the index of all clothes washer pages.
