Diagnosis
That's an imbalance issue. Either the load inside is bunched up, or the washer isn't level on its feet.
How to Fix It
First, pause the cycle and redistribute the clothes evenly in the drum. Then, check the leveling: use a bubble level on top of the washer. Adjust the front feet by turning them clockwise to raise or counterclockwise to lower. The rear feet are self-leveling but ensure all four are firmly on the floor.
If That Didn't Work
Verify the shipping bolts were removed during installation. On this model, there are usually four bolts at the back holding the drum for transit; if left in, they cause massive vibration.
Heads Up
Overloading is a prime culprit. This washer holds about 4.5 cubic feet—stick to medium loads for balance, and mix large and small items.
