- SLWW2403***
To verify the SUMMIT SLWW2403: at DOE's test use it draws 302 kWh a year with an electric water heater and an electric dryer. It also uses 2,142 gallons of water a year at that same test use. Its IMEF, the cubic feet of laundry washed per kilowatt-hour, dryer included, is 2.15, below its class median of 2.76.
Energy and water per year
302 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.
2,142 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 302 kWh figure is computed by this site, not filed by the registry. It combines the registry's IMEF of 2.15 with a capacity, the drum's volume in cubic feet, of 2.2, at DOE's test use. Because IMEF folds the dryer in, that yearly total includes energy for drying, not only for washing. DOE's database does not publish a machine-only figure, the washer's own share without the dryer. ENERGY STAR alone splits the machine out, and it lists this model under no matching rating. So this page shows no machine-only energy for the SLWW2403, and no installed price range, which needs that same figure. The method, using registry data retrieved 2026-10-25, is set out under how the yearly energy and water figures are calculated.

The 2,142 gallons yearly water figure is also computed by this site rather than filed by the registry. It starts from IWF, the gallons of water used per cycle for each cubic foot of drum, which is 3.3 here. That factor is applied to the 2.2 cubic-foot drum at DOE's test use for a year. The figure holds at that test use; it is not a measurement from a particular household. No cost is given for the 2,142 gallons, because no free national source publishes local water and sewer rates. The water cost for this model is therefore unknown on this page, and the page does not estimate one.
Among the 360 models registered as front-loading, standard size, the SLWW2403 has the 292nd highest IMEF. Its IMEF of 2.15 sits below the class median of 2.76, but above the federal minimum IMEF for its class. In that class, 37 models sit at the federal minimum, and this model is not one of them. In the registry, this model is sold as SLWW2403***, the entry these figures are drawn from. The running cost of the 302 kWh depends on your own utility electricity tariff, so the page computes it from your ZIP. Other models in the class can be checked from all clothes washer pages.
