Hello Military Wife and Mom,
The usual cause of this type of thing; the clothes inside of washer have shifted to one side of the tub, to remedy this--turn washer off--open lid and move articles inside- distribute them as evenly as possible.
Another cause can be if you are washing one large article (rug/blanket,etc). The washer will be more apt to go unbalanced with this situation.
Even when washing one large item--just open lid and try to distribute article evenly as possible and restart.
Hope this helps
In Christ,
