- WF45K65**A*
Checking the SAMSUNG WF45K65**A*? At DOE's test use, it takes 474 kWh a year with an electric water heater and an electric dryer, and 3,982 gallons of water. Its IMEF, the cubic feet of laundry washed per kilowatt-hour, dryer included, is 2.8, above the class median of 2.76.
Energy and water per year
474 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: 100 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.
3,983 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 474 kWh figure counts the washer, the electricity that heats its water, and the energy an electric dryer uses on the same loads. This site computed it from the registry's IMEF and capacity, the drum's volume in cubic feet, which is 4.5 for this model. The yearly total itself is not a registry value. ENERGY STAR files a separate machine-only figure of 100 kWh a year. That covers the machine and its electrically heated water alone, with the dryer left out. The gap between the two numbers is the dryer's share under DOE's test use. The total reflects DOE's test conditions, with data retrieved from the DOE Compliance Certification Database on 2026-10-25. A household that washes more or fewer loads than the test assumes will see a different total. The steps are set out in how the yearly energy and water figures are calculated.
Read the rest
The water figure of 3,982 gallons a year is also this site's calculation rather than a registry value. It starts from the registry's IWF, the gallons of water used per cycle for each cubic foot of drum, which is 3 for this model. That factor is applied across the 4.5 cubic-foot drum and DOE's yearly cycle count. The page gives no water cost for this washer. No free national source publishes local water and sewer rates, so any amount would be a guess. A reader who knows the local rate can apply it to the 3,982 gallons figure directly. Electricity is treated the same way in this text. Its running cost depends on the reader's own utility tariff, so the page computes it from the reader's ZIP instead of stating it here.
Among the 360 models registered as front-loading, standard size, this washer's IMEF of 2.8 ranks 98th highest of 360. The class median is 2.76, so this model sits above it. It is also rated above the federal minimum IMEF for its class, where 37 of the 360 models sit at that minimum. A higher IMEF means more cubic feet washed per kilowatt-hour under the test, dryer included. The rank compares test ratings only and says nothing about how a unit performs in a given home. The installed-cost range shown in its own block on this page is a modeled range with its own source and date, not a quote. Other models in this class and in other classes are listed on all clothes washer pages.
