LG WM3400CW Washer Dimensions
Published 2026-07-24 ยท Category: washer
The LG WM3400CW is a 4.5 cu. ft. front-load washer. As a 27-inch front-load model, it is shorter and deeper than most top-load washers, and its door swings outward, which affects how much floor space is needed when the drum is loaded.
Manufacturer specs list the WM3400CW at 27 inches wide, 39 inches tall, and 30.25 inches deep. With the door open 90 degrees, the required depth grows to 55 inches. The unit weighs 187.4 lb and runs on a 120V, 10A circuit.
The 55-inch door-open depth is one of the larger values in its class. This measurement is the most common point of conflict in laundry closets, where a narrow door or adjacent wall can block the door swing. The cabinet itself is a typical 27 inches, matching standard front-load washer cutouts.
Capacity of 4.5 cu. ft. is slightly below the 4.8 cu. ft. of the top-load washers in the dataset, which is typical for compact 27-inch front-load drums. The electrical requirement is only 10A at 120V, making circuit demands modest. At 187.4 lb, it is one of the heavier washers in this catalog, so delivery paths and floor loading should be checked.
The table below summarizes the verified dimensions and electrical requirements. For comparisons with top-load washers, see the standard washer sizes guide or the front-load vs top-load washer dimensions comparison.
