The Midea MAH180-S2803PS/01FM-US uses 846 kWh a year with an electric water heater and an electric dryer, and 8,629 gallons of water, at DOE's test use. Its IMEF, the cubic feet of laundry washed per kilowatt-hour, dryer included, is 1.57, the same as the class median of 1.57.


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 energy figure of 846 kWh is calculated by this site, not filed by the registry. It combines the registry's IMEF of 1.57 with the capacity, the drum's volume in cubic feet, which is 4.5 cubic feet for this model. It assumes DOE's test use, an electric water heater and an electric dryer. Because IMEF folds the dryer in, the figure is not the washer's own draw. The machine-only share is not available: ENERGY STAR splits it out, but lists no matching rating for the MAH180-S2803PS/01FM-US, sold as MLTW45M4BWW. The DOE CCD data were retrieved on 2026-10-25. How the yearly figures are calculated is set out in the methodology.

The water figure of 8,629 gallons comes from the IWF, the gallons of water used per cycle for each cubic foot of drum. The registry lists an IWF of 6.5 for this model, and the site multiplies it by the capacity of 4.5 cubic feet at DOE's test use. The class median IWF is not available on this page, so the water figure is not compared with other models. The cost of this water is not stated: no free national source publishes local water and sewer rates, and this page does not estimate one.

Read the rest

The class here is the 870 models registered as top-loading, standard size. Their median IMEF is 1.57, and this model's IMEF of 1.57 matches it, so there is no difference to report in either direction. The running cost of 846 kWh depends on your own electricity tariff, so the page computes it from your ZIP rather than in the text. The installed price range is not published: the cost database needs the washer's own yearly energy, which only ENERGY STAR files. Other models are listed on all clothes washer pages.
