A:Answer When the ENERGY STAR® Certified LG 5.0 Cu. Ft. High-Efficiency Stackable Front Load Washer with 6Motion Technology - Middle Black, Model # WM3470CM, runs smoothly through an empty spin cycle, but vibrates excessively and slides during a regular wash with clothes, it is almost always caused by an inability to handle an unbalanced load, typically due to improper leveling, weak floor support, or failing internal suspension components. The load creates centrifugal force that amplifies, causing the machine to walk or vibrate.
Since this is a new washer, failing internal suspension components is not the issue.
Using the washer without leveling it may cause excess vibration and noise, leading to a washer
malfunction. The leveling feet should only be adjusted as far as necessary to level the washer. Extending the leveling feet more than necessary can cause the washer to vibrate. The floor should have been clean, dry, and free of dust, dirt, water, and oil before the washer was installed, so the washer's feet cannot slide easily. Feet that move or slide on the floor can contribute to excessive vibration and noise
The washer's drum spins at very high speeds. To minimize vibration, noise, and unwanted movement, your floor must be a solid, level surface...^Ivan.
