Is the washer placed directly on the floor and not on the optional pedestal?
When the washer is not on a pedestal, all four washer feet need to be in firm contact with the floor. Try to rock the washer diagonally, from corner to corner, with your hands; adjust the feet if the washer teeters. The lock nuts on all four of the feet should be tightened against the washer cabinet. See the information below on how to make corrections.
