How do I permanently level my Maytag Neptune washer?

Question:I continually have to re-level my maytag neptune washer. After a couple months being level, it slowly get's out of level and causes all sorts of commotion and noise. I have a "platform" drawer and rubber feet on ceramic tile. I'm almost considering dropping in some bolts into the concrete foundation to keep this thing from moving all over the laundry room floor.

Answers:
When you get the machine level again, put some Loc-tite on the bolt threads to keep them from vibrating loose. If you don't have any Loc-tite, a dab of nail polish will do.
