Your washer wasn’t shaky when you got it, so why is it shaky now? If your unit begins to shake or move when a wash cycle is operating, this is a sign of an unbalanced load. The start of a wobbly washer usually happens over time as different parts that act as a precaution in preventing this become warn out. The three parts responsible for offering stability during off balance loads are: the leveling legs, shock absorber and suspension spring.
