Gibson Washer is unbalanced
If your Gibson washer is unbalanced, shaking, or moving during the spin cycle, start with the simplest and most likely cause: the washer is not level. Check that all four leveling feet are firmly touching the floor and that the cabinet does not wobble when you press on its corners. Adjust the leveling feet until the washer sits solidly, then use a bubble level to confirm it is level from front to back and side to side. A washing machine that is unbalanced or a washer that keeps going off balance can make loud banging noises, shift across the floor, and leave clothes unevenly distributed. If the unit cannot be leveled, the floor or the washer’s leveling foot may need service. This Gibson washer repair guide focuses on leveling problems, which are highly likely causes of a washer shaking or a washing machine unbalanced condition. If leveling does not correct the problem, inspect the suspension and shock absorption system, including suspension rods, shock absorbers, tub springs, the balance ring, or snubber ring.
