Unbalanced load? Too much soap? Too heavy and caused it to go off balance

Because quilts, towels, etc. hold a lot of water, they will only release that water during the spin cycle. If the spin rate is too high, the machine will sling water over the top of the tub thence down and onto the floor. To prevent this, reduce the spin rate from high to low. If you find they are still too wet, run a second spin, only, cycle on a higher setting.
