We have a Whirlpool Gold Catalyst Three-Speed Electronic Washer Model
No. GSX9885JQ1, Serial No. CP4602130 installed in April 2003. On the
clothes washer's slowest spin cycle, vibration radiates out to 15'
enough to loosen drywall screws and cause moldings to separate at
seams. On the regular spin cycle, the vibration is awful.

Try running the washer through its cycles, first with no water, then with.
This should eliminate any possibility that the load is the culprit.

In both these tests you should be able to balance a coin on edge throughout
the entire washing process. Well, maybe not a coin, but you get the idea.

If the machne shudders like the hinges on the gates of Hell, you should call
Whirlpool and fuss like the third monkey on Noah's gangplank.
