The LG
WM3997HWA is part of the
Washer-Dryer Combo test program at
Consumer Reports. In our lab tests, All-In-One Washer-Dryers
models like the WM3997HWA are rated on multiple criteria, such as those
listed below.
Washing performance:
This reflects the degree of color change to stained swatches of fabric that were included in an 8-pound test load of mixed cotton items using the machines' most aggressive normal cycle. (We do not use special cycle or option buttons.)
Washer energy efficiency:
Indicates the energy needed to heat the water, run the washer, and remove the water left in the clothes after the spin cycle completes.
Water efficiency:
This score denotes how much water it took to wash our 8-pound load. On models that didn't set the fill level automatically, we used the lowest fill setting that sufficed for the 8-pound load. We then calculated water used per pound of clothing.
