A:Answer If the 2016 ENERGY STAR® Most Efficient LG 4.5 cu. ft. High-Efficiency Front Load Washer with Steam and TurboWash in Black Stainless Steel, Model # WM4370HKA has been installed on a floor that is strong and rigid enough to support the weight of the washer when fully loaded without flexing or bouncing, it should not vibrate. You also need to make sure that it is properly leveled and that the leveling feet are not raised unnecessarily high as that will cause the machine to vibrate. Use of drip pans and failure to properly level the machine may result in increased vibration and noise during operation. If a drip pan must be used, take extra care to follow the instructions provided with the drip pan and make sure the leveling feet are adjusted for firm and even contact with the pan. It is also recommended not to wash waterproof or water resistant clothes as those may also cause abnormal vibrations or may cause the load to bounce which could damage the tub or result in property damage.
