- WA51A5505A*
If you are checking the Samsung WA51A5505A*, this top-loading washer uses 730 kWh a year with an electric water heater and an electric dryer, at DOE's test use. At that use, it also uses 6,469 gallons of water a year. Its IMEF, the cubic feet of laundry washed per kilowatt-hour, dryer included, ranks 37th highest of 870 top-loading, standard-size models.
Energy and water per year
730 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: 120 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.
6,469 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.

At DOE's test use, the 730 kWh figure covers the washer, an electric water heater and an electric dryer together. This site computes the figure; the registry does not publish it. The inputs are the registry's IMEF of 2.06 and its capacity, the drum's volume in cubic feet, of 5.1. Both come from DOE's Compliance Certification Database, retrieved 2026-10-25. ENERGY STAR files a separate figure of 120 kWh a year for the machine and its electrically heated water alone. That figure leaves out the dryer. The difference between the two figures is the dryer's share at the same test use. This text gives no running cost, because the cost depends on your own utility's electricity tariff. The page calculates it from your ZIP code instead.
Read the rest
This site also computes the 6,469 gallons figure, using the model's IWF, the gallons of water used per cycle for each cubic foot of drum. This model's IWF is 4.3. The site applies it to the 5.1 cubic feet of drum over DOE's yearly test cycles. A lower IWF means less water per cubic foot each cycle. Your own yearly use will differ if your household runs more or fewer loads than the test assumes. This page states no water or sewer cost for this model. No free national source publishes local water and sewer rates, so any figure here would be an estimate. The method behind the yearly energy and water figures explains how both totals are calculated.
This model is compared with the 870 models registered as top-loading and standard size. The median IMEF in that class is 1.57. At 2.06, this model sits above the median and ranks 37th highest of the 870. In the class, 652 models are rated at the federal minimum IMEF. This model is rated above that minimum, but the minimum value itself is not available in the data behind this page. The rank compares rated IMEF only and does not reflect water use. An installed price range appears in its own block on this page, with its source and date. It is a modeled installed-cost range, not a quote. You can check other models from the index of clothes washer model pages.
