I just bought a brand new washing machine (Whirlpool GSW9800P) and I'm
having a hard time getting it balanced. It's sitting on a linoleum
floor and every time it goes into its spin cycle it starts to shake,
rattle and move across the floor. I've tried adjusting the front legs
repeatedly, but it's just not doing the trick (either that, or I just
haven't found the magically height). Any suggestions on what I can
do/try?

Thanks.
