Don't know whether your still looking for answer or not. Actually the answer
is quite simple. All washers need to be 'leveled' when installed. There are
four adjustable legs under the washer that need to be screwed in or out to
level the machine (so that it doesn't rock from side-to-side or
front-to-back).
First determine which way the washer is out of balance and then screw down
the leg on the "high" side. (Washers need to be leveled to prevent
vibrations when the load is off-center, but it's NOT at all important as to
whether they are bubble level front-to-back or side-to-side (so don't worry
about that aspect). Just need to get it all four legs positioned to take
equal portions of the weight.
