  • WFW8540F*

If you are checking the Whirlpool H16NAZ55(3B), it uses 455 kWh of electricity a year with an electric water heater and an electric dryer. It uses 4,248 gallons of water a year, both at DOE's test use. Its IMEF, the cubic feet of laundry washed per kilowatt-hour, dryer included, is 2.92, above its class median of 2.76.


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

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.

4,248 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.

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 front-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

This site calculated the 455 kWh figure; the registry did not file it. It combines the registry's IMEF of 2.92 with the model's capacity, the drum's volume in cubic feet, of 4.5 at DOE's test use. Because IMEF folds the dryer in, the total includes the dryer's share along with the washer and the electric water heater. A machine-only figure is not available for this model. DOE's database files IMEF alone, and only ENERGY STAR splits out the washer's own share. ENERGY STAR lists no matching rating for the H16NAZ55(3B), so that share is unknown. For the same reason, no installed price range is published, because the cost database needs the machine-only figure. The steps are set out in how the yearly energy and water figures are calculated. The energy data was retrieved from DOE CCD on 2026-10-25.

Read the rest

This site also calculated the 4,248 gallons yearly water figure. It uses the registry's IWF, the gallons of water used per cycle for each cubic foot of drum, of 3.2. That value is combined with the 4.5 cubic feet of capacity at DOE's test use. A household that runs more or fewer loads than the test assumes will have a different total. No water or sewer cost appears next to the 4,248 gallons. No free national source publishes local water and sewer rates, so the page does not estimate a cost. A reader who knows the local rate can apply it to the gallon figure directly.

There are 360 models registered as front-loading, standard size, and the H16NAZ55(3B) has the 33rd highest IMEF among them. Its IMEF of 2.92 is above the class median of 2.76. It is also above the federal minimum IMEF for its class, and 37 models in the class are rated at that minimum. The registry lists this model as sold under WFW8540F*. This text does not state a running cost. The cost depends on your own utility's electricity tariff, so the page calculates it from your ZIP instead. Other models in the same class can be checked through all clothes washer pages.
