The part(s) or condition(s) listed below for the symptom Washer vibrating or shaking are ordered from most likely to least likely to occur. Check or test each item, starting with the items at the top of the page.
One or more of the shock absorbers might be broken or worn out. The shock absorbers dampen the vibration of the washer tub. If one or more of the shock absorbers are worn out, the washer will vibrate or shake. Sometimes, when a washer is moved to another location, the shock absorbers can separate. Check the shock absorbers to ensure that they are positioned correctly, and inspect them for damage and wear. If one or more of the shock absorbers are broken or worn out, we recommend replacing all of the shock absorbers as a preventative measure.
One or more of the suspension springs might be broken. The suspension springs help to absorb the movement of the washer tub. If a suspension spring breaks, the tub might become unbalanced, causing it to shake and vibrate during operation. Inspect the suspension springs to determine if any of the springs are broken. If a suspension spring is broken, replace it.
Washer vibration can occur if the shipping bolts have not been removed. All front loading washers are delivered with shipping bolts to stabilize the drum system during transportation. The bolts are located at the back of the washer and they must be removed before use otherwise the machine will shake and bounce around significantly.
The rear drum has a bearing or bearings in it to keep the inner tub spinning smoothly. If the tub bearing system is defective the washer can develop a bad vibration. On some machines bearings are sold separately from the rear drum, however we recommend replacing both the outer drum and bearing as an assembly if the manufacturer offers the components together because removing and pressing in the new bearing can be exceptionally difficult. Be aware that replacing the outer tub and bearing is also not easy and can be very costly.
