My washing machine shakes so violently during the spin cycle that it moves across the floor. The whole house vibrates.
Violent shaking during spin is caused by an unbalanced load, uneven legs, worn shock absorbers, or a damaged suspension spring. First, open the machine and redistribute the clothes evenly. A single heavy item like a towel or blanket causes extreme imbalance. Next, check that the machine is perfectly level: place a spirit level on top and adjust the feet until the bubble is centered in both directions. All four feet must be firmly on the floor with no rocking. If the machine was recently installed, check that the shipping bolts were removed — shipping bolts lock the drum for transport and cause severe vibration if left in place. For front-load washers, worn shock absorbers let the drum bounce during spin. You can check by pushing down on the drum through the door opening — it should resist and spring back, not bounce freely. Shock absorber replacement costs 40 to 100 dollars for a set of two.
