Kenmore Washer Shaking Violently During Spin: Balance, Level, Then Stop
A Kenmore washer that shakes violently during spin should be stopped safely and checked for a bunched or oversized load, an uneven floor, or feet that are not making firm contact. Kenmore's own laundry guidance says an unbalanced washer can make a lot of noise and recommends using a level and adjusting the feet; it also recommends a balanced load that lets clothes move freely rather than overloading or underloading.
