We have 2 front loaders - washer and dryer. They sit on a concrete floor in the basement. The floor is not level. Both sit on shop made stands made from 4x4 and doubled up 3/4" ply. The dryer is shimmed with wood. The washer, on the other hand walks around regardless of the shim material. I used wood, metal, various types of rubber but it still walks. Presumably, this is because of the violent agitation during the spin/dry cycle.
I'm an old guy and pushing the unit back in place is getting more difficult. I'd love to hear any suggestions on how to anchor this unit into place.
Thanks,
Burt
