  • W47ATG1BG

If you are checking the KTN MAV180-A2804PS/01FM-US, sold as W47ATG1BG, here are its registry figures. At DOE's test use it takes 846 kWh a year with an electric water heater and an electric dryer, plus 8,629 gallons of water. Its IMEF, the cubic feet of laundry washed per kilowatt-hour, dryer included, is 1.57, the federal minimum for its class.


Energy and water per year

846 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.

8,629 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 exactly at the federal minimum IMEF for its class, like many others; no rank is claimed inside that tie.

What you can do. Federal minimum means this model uses as much energy as the law allows for its class. 218 washers in the same class file a higher IMEF; at the same drum size and use, a higher IMEF is less energy a year. See the most efficient washers in each 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 top-loading washers. That is a class assumption, not this model’s rating or a warranty — no registry publishes either.

No CPSC recall names this model.

Checked against the CPSC recall database. CPSC does not publish a model-level match for this product category, so this list is curated by hand from the manufacturer's recall filings.

What these figures mean

The 846 kWh figure is this site's calculation, not a registry value. It combines the registry's IMEF of 1.57 with the washer's capacity, the drum's volume in cubic feet, which the registry gives as 4.5. Both are applied at DOE's test use. Because IMEF folds the dryer in, the total covers washing, heating the water electrically and drying the load. DOE's Compliance Certification Database, retrieved 2026-10-25, files only that combined IMEF. A machine-only figure for the MAV180-A2804PS/01FM-US is not available. Only ENERGY STAR splits out the washer's own share, and it lists no matching rating for this model. For the same reason, no installed price range is shown, since the cost database needs that machine-only figure. The method behind the yearly energy and water figures sets out each step.

Read the rest

The 8,629 gallons a year comes from the registry's IWF, the gallons of water used per cycle for each cubic foot of drum. For this model the IWF is 6.5. This site multiplies it by the 4.5 cubic feet of capacity at the same DOE test use. The figure therefore reflects DOE's test conditions, not the loads of any given household. The cost of that water is not stated on this page. No free national source publishes local water and sewer rates, so any cost placed on the 8,629 gallons would be an estimate. A reader who knows the local water and sewer rate can apply it to the gallon figure.

Among the 870 models registered as top-loading, standard size, the median IMEF is 1.57. This model's IMEF of 1.57 matches that median and sits exactly at the federal minimum for the class. It shares that minimum with the other models counted in the 652 rated there, out of 870. Because so many models tie at the minimum, no rank is claimed for this model inside the tie. The running cost is not given in this text. It depends on your own utility electricity tariff, so the page computes it from your ZIP against the 846 kWh total. Other models in the class are listed on the clothes washer pages.
