Most concerns, if not all, regard washers that are located on the second floor of a home, or where the washer is installed on a plywood platform.
Washers located on a second floor home will cause vibration. When a washer is installed in these conditions the laundry room floor should be reinforced, professionally, by a carpenter using 1” plywood properly screwed and glued to the original 5/8” flooring. In a few instances, very heavy, barn rubber mats can help eliminate vibration –“IF”- the floor can be reached from the basement to properly reinforce this area.
Not even a Samsung with VRT can avoid the issue of vibration in these type of installations.
