- WF45R63**A*
To verify the SAMSUNG WF45R63**A*: with an electric water heater and an electric dryer, it uses 455 kWh a year at DOE's test use. Its yearly water use at that test use is 5,974 gallons. Its IMEF, the cubic feet of laundry washed per kilowatt-hour, dryer included, is 2.92, the 33rd highest of 360 washers in its class.
Energy and water per year
455 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: 95 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.
5,974 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 455 kWh figure is computed by this site, not the registry. It combines the registry's IMEF with the model's capacity, the drum's volume in cubic feet, which is 4.5 here. Because IMEF counts drying, that yearly total includes an electric dryer's work on each load. ENERGY STAR files a separate machine-only figure for this model: 95 kWh a year. That covers the washer and its electrically heated water alone, so the difference from 455 kWh reflects the dryer's share. The registry lists more than one rating for this model, and this page shows the least efficient one. The inputs come from DOE's Compliance Certification Database, retrieved 2026-10-25, and how the yearly energy and water figures are calculated explains the steps.

The 5,974 gallons figure is also computed by this site. It uses the registry's IWF, the gallons of water used per cycle for each cubic foot of drum, which is 4.5 for this model. That factor is scaled by the 4.5 cubic-foot capacity and DOE's yearly count of test cycles. The result holds at DOE's test use, so a household running more or fewer loads will see a different total. Heating that water is not a separate line here, because its electricity is already inside 455 kWh. No cost is shown for the 5,974 gallons. No free national source publishes local water and sewer rates, so this page does not estimate one.
This model is compared with the 360 models registered as front-loading washers of standard size. Its IMEF of 2.92 is above the class median of 2.76, and a higher IMEF means more laundry per kilowatt-hour. By IMEF it ranks 33rd highest of the 360, and it is rated above the federal minimum for its class. In the class, 37 models are rated at that minimum. Running cost is not stated in this text, because it depends on your own utility's electricity tariff. The page computes it from your ZIP code instead. Other front-loading models can be checked from all clothes washer pages.
