What people are saying

Rated 4 out of 5 by from Great washer. Poor Sam’s Club/LG Installation Meant to be white glove installation. They used old hoses and when I turned water on both ends leaked. And they did not remove the shipping bolts. However machine is great. Quiet, uses a lot less water. Have to make sure after use you leave door open to dry out seal.

Does this machine have autable beeps

Asked by: Brig12
The ENERGY STAR® Qualified LG 4.5 cu. ft. Ultra Large Front Load Washer Model # WM3400CW, does not make audible beeps, it plays melodies and it chimes. When the cycle is finished, a melody sounds. The washer includes several additional cycle options to customize cycles to meet your individual needs. When you select your desired option after selecting your desired cycle and settings, the LED for the option will light when the option is selected. A chime will sound twice and the LED will not light if the selected option is not allowed for the selected cycle. Not all modifiers and options are available on all cycles. A different chime sounds and the LED does not light up if the selection is not allowed..^Ivan

How do I add Mrs. Stewart's Bluing to the washer? Drawers aren't big enough to hold the dilution. If it needs to be added to the final rinse, how do I know when that occurs? Do I have to sit around and wait for it and guess if it is the final rinse?

Asked by: MnM1975
You have to follow the manufacturer's directions on the packaging for your Mrs. Stewart's Bluing for how and when to add it to the ENERGY STAR® Qualified LG 4.5 cu. ft. Ultra Large Front Load Washer, Model # WM3400CW. The instructions can be found on the back of each bottle of Mrs. Stewart'sBluing. The instructions do not mention anything about adding the bluing in the final rinse. If you need further assistance, we highly recommend that you contact Mrs.Stewart'sat https://mrsstewart.com/pages/contact-us...^Ivan

Which was does the door open? Can it be ordered right hand hinge?Texas

Asked by: Texas Grandma
All of our LG Front Load Washers, including the ENERGY STAR® Qualified LG 4.5 cu. ft. Ultra Large Front Load Washer, Model # WM3400CW are left swing door models (see images 5 and 6 ). Regrettably, due to the electronics & wiring in the front load washers, they cannot be ordered as right swing door washers...^Ivan

Washer spins extremely fast and loud, and shakes. What is problem.

Asked by: Spunky 201
Like all other Front Load Washers, the ENERGY STAR® Qualified LG 4.5 cu. ft. Ultra Large Front Load Washer, Model # WM3400CW is designed to spin fast (Max RPM 1300) so it can extract as much water as possible from your laundry. To minimize noise and vibration, the washer should be installed on a level, solidly constructed floor that is capable of supporting the washer without flexing or bouncing during the spin cycle. Concrete flooring is best, but a wood floor is sufficient, provided it is built to FHA standards. The floor under the washer must not slope more than 1 inch (2.5 cm) from front to back or side to side and you need to make sure that the floor is clean, dry, and free of dust, dirt, water, and oil so the leveling feet cannot slide easily. Leveling feet that can move or slide on the floor can contribute to excess vibration and noise...^Ivan

How many gallons of water does my LG 3400cw use per washing load

Asked by: Suzbri
The specifications do not offer water usage for the wash cycles. On average a washers with a capacity between 4 and 5 cubic feet uses 15.6 gallons of water per load. Most high-efficiency washers use only 15 to 30 gallons water to wash the same amount of clothes as older washers (29 to 45 gallons per load). The most efficient washers use less than 5 gallons (18.9 L) per cubic foot of capacity. Model WM3400CW is a high-efficiency washer, and the water levels may be much lower than you expect. The washer automatically adjusts the water level for the type and size of wash load for best results and maximum efficiency. ^Daphane
