Front Load Washer Vibrates Excessively
Is the washer level?
A common reason a washer vibrates is the machine is not level. Level the washer and try again. Note that the higher the machine is, the more it'll vibrate.
Is the load balanced?
If the load is unbalanced, the machine may vibrate more than usual. To fix, simply stop the machine and redistribute the load.
Is the shipping bolt still in the machine?
New washing machines are delivered with a shipping rod installed to keep the tub from moving too much during shipping. The rod keeps the unit stable to prevent damage while the machine is being transported. If the rod isn't removed during the installation, there will be a lot of noise and vibration during operation. Make sure to remove it before using the washing machine.
Important: Unplug the washer from its power source before starting any inspection or repair work.
Shock absorbers installed in your machine to minimize tub movement during the spin cycle. They're attached to the base and the outer tub. Faulty or worn out shock absorbers are unable to do their job, so things like unbalanced loads can make the washer vibrate or even move.
To access them, you'll need to remove the front and/or rear panels. A damaged shock absorber should be replaced as soon as possible, as that one faulty part can lead to serious damage to other parts of the machine.
Washing machines attach the tub to the cabinet with suspension springs. This spring stabilizes the tub assembly and absorb vibrations produced during the spin cycle. If the suspension spring is damaged, the vibration won't be dampened effectively, and that'll cause the entire machine to vibrate excessively.
Use extra caution when inspecting this part, as springs are under tension and you must be careful about it snapping when you disconnect it from the tub or cabinet. If one is bad, it's recommended to replace all of them at the same time.
