Please stop using your washer!!! THIS IS A TEMPORARY REQUEST! I had the same problem with mine when I first got mine home. The reason for your washer jumping and seemingly walking, I believe, are certain locks on the back of your washer that have not been removed. There are, if I remember correctly, 4 of those locks on the back that can be easily unscrewed and that will resolve your walking washer. They have what looks like a silver washer with a black rubber sealants under the silver washer. REMOVE ALL 4 or so. Your washer should be stationary afterwards.
