We purchased a front loading washer for our son & his wife. They have an older home (1920-30). They have renovated the 2nd floor & made a laundry room up there. When they used the washer, apparently the vibration when it was spinning shook the whole house. They were told this always occurs when installing a front loading washer on upper levels of a house. They really want an Energy Star appliance & cannot use it as it is now. Has anyone found a solution to this problem other than moving it to the basement?
