LG Front Loader Washer is Off Balance

Our LG has done that one time, and it was I had just put too many clothes in it. What I did was just re-arranged the clothes a little, then restarted it. That worked. Even though it is a super size, it still has its limits.

Do you have a cement floor? If not it could be the floor is moving when you are doing laundry. We had to put a sheet of plywood under our daughter's washer & dryer. It worked, good luck.

This happened to me before, I would check to make sure that the clothes/items in your washer are not uneven. That is, that they are evenly distributed around the washer. That was the cause of my washer jumping around. Even if you don't think they look uneven, trying moving them around. It might work. Good luck!
