Fixit: When doing the wash means vibrating the house

QThe front-loading washer and dryer are on the second floor of our newly built home. When the washer is on the spin cycle, the entire house vibrates, especially the light fixtures on the first floor. The laundry room is directly above the garage. What can I do to stop the vibration? Aside from the vibration, the washer works wonderfully.
AFront-loading washers spin at very high speeds and that can create vibration. But front-loading washers are designed to operate quietly. Vibration shouldn't be a problem, unless loads are unbalanced or there's a problem with installation.
Washing machines -- top-loading or front-loading models -- can become unbalanced when there's a difference in weight between items being washed, such as a towel thrown in with underwear. Well-built front-loaders (typically the more expensive digital models) are designed to control vibration, even shutting down and alerting you to unbalanced loads.
To prevent unbalanced loads, sort laundry carefully.
Another cause for vibration is using too much detergent. Front-loaders use tablespoons of detergent rather than the cupful you may be accustomed to putting in a washer. Too much detergent causes over-sudsing and that acts like a mismatched load.
Check the owner's manual for tips on troubleshooting vibration. The manual also may include a manufacturer's consumer information number for advice.
If you've done all that's suggested and the problem persists, it may be an installation problem. Contact the installer or your home's builder to let them know of the problem. One reader wrote:
"If the washer is installed so the rotation of the drum is parallel to the joists under the floor where the washer is located, the spin cycle can produce a 'harmonic vibration' that not only can be very annoying, but can shake the house. A header structure under the joists below the washer must be set up to provide some structural rigidity to withstand the vibration."
Some recommend controlling vibration by setting the unit on a slab of plywood attached to the floor.
The folks at This
Old House magazine suggest placing a slab of hard rubber, such as vehicle mud flaps, under the legs to absorb the vibration.
The ultimate solution to vibration, in same cases, is to move the unit to the basement so it's on a concrete floor.
