If you are checking the Koolmore MAV180-A2404PS/01FM-US, sold as KM-TLW-4CW, at DOE's test use it comes to 770 kWh a year with an electric water heater and an electric dryer, and 7,862 gallons of water a year. Its IMEF, the cubic feet of laundry washed per kilowatt-hour, dryer included, is 1.57, equal to its class median of 1.57.
Energy and water per year
770 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.
7,862 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.

Every clothes washer on file
All four product classes, from the DOE registry.
The 770 kWh figure assumes an electric water heater and an electric dryer. This site computed it, not the registry. It uses the washer's IMEF of 1.57 and its capacity, the drum's volume in cubic feet, of 4.1. The calculation applies DOE's test count of cycles per year, set out in how the yearly energy and water figures are calculated. The inputs come from DOE's Compliance Certification Database, retrieved 2026-10-25. Because IMEF folds the dryer in, 770 kWh includes energy spent drying each load, not only washing it. A machine-only figure is not available for this model. Only ENERGY STAR splits the washer's own share out, and it lists the MAV180-A2404PS/01FM-US under no matching rating. For the same reason, no installed price range is published here, because the cost model needs that machine-only figure.
Read the rest
The water figure of 7,862 gallons a year is also this site's calculation, not the registry's. It starts from the model's IWF, the gallons of water used per cycle for each cubic foot of drum, which is 6.5. That value is multiplied by the 4.1 cubic feet of drum and DOE's test count of cycles. The result reflects DOE's test use, not a particular household's washing pattern. The cost of that water is not shown. No free national source publishes local water and sewer rates, so no amount is given. The electricity cost is also not in this text. It depends on the reader's own utility tariff, so the page computes it from the reader's ZIP. At 770 kWh a year under the electric water heater and dryer scope, that rate sets the result.
This model is compared with the 870 models registered as top-loading, standard size. The median IMEF in that class is 1.57, and this model's IMEF of 1.57 sits exactly at that median. It is also rated exactly at the federal minimum IMEF for its class. That position is shared: 652 of the 870 models sit at the same minimum. No rank is claimed inside that tie. A plumber or seller verifying this listing can compare the rated IMEF of 1.57 and IWF of 6.5 with DOE's entry for MAV180-A2404PS/01FM-US, sold as KM-TLW-4CW. Other top-loading and front-loading models appear on all clothes washer pages, each with its own class figures.
