- WGA14400UC
If you are checking the Bosch WGA12400UC, DOE's test use gives 251 kWh a year with an electric water heater and an electric dryer, and 2,292 gallons of water. Its IMEF, the cubic feet of laundry washed per kilowatt-hour, dryer included, is 2.47, below the class median of 2.76.
Energy and water per year
251 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.
2,292 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.

The 251 kWh covers the wash and the dryer's share, because DOE's database files IMEF, which folds the dryer in. This site computed it from the registry's IMEF of 2.47 and the capacity, the drum's volume in cubic feet, listed at 2.1, at DOE's test use. The data was retrieved 2026-10-25. The machine-only energy is not published for this model: only ENERGY STAR splits the machine out, and it lists no matching rating for WGA12400UC. The installed price range is also not available, for the same reason. The registry records this model as sold as WGA14400UC. For the method, see how the yearly energy and water figures are calculated.
The 2,292 gallons is a test-use total, not a reading from any household. This site computed it from the registry's IWF, the gallons of water used per cycle for each cubic foot of drum, which is 3.7 for this model, and from the 2.1 cubic feet capacity. A home that runs a different number of cycles will use a different volume, and that case is not available here. 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. The water figure and the energy figure share the same test-use basis, so they can be read side by side.

Among the 360 models registered as front-loading, standard size, the class median IMEF is 2.76. This washer's IMEF of 2.47 is below that median, which means less laundry washed per kilowatt-hour, dryer included, than the median model. This comparison uses registry values only and says nothing about how the machine performs in use. The 251 kWh applies only to an electric water heater and an electric dryer; figures for gas equipment are not available. Running cost depends on your own utility electricity tariff, so the page computes it from your ZIP and the text names no amount. Browse all clothes washer pages for other models in the registry.
