An off balance washer is a very noisy inconvenience. However, if not taken care of, the off balance washer can result in serious damage to itself. One of the main reasons a washer goes off balance is when the laundry is loaded off balance. To help fix this issue, ensure laundry is loaded so that it is equally distributed.
Another reason washers go off balance is because they are not on level feet. If the washing machine can be rocked in any manner, the feet are not leveled. A professional can easily help you get your washer leveled so that the basket can spin correctly.
