Washer doesn't sit level in new laundry room

A washing machine may wiggle, rattle or move across the floor. It is often accompanied by excessive, or loud noise. There can be several causes and the problem is worse with some units more than others.The most common cause is an unbalanced wash load. Open the lid/door, and attempt to redistribute the clothing to balance the weight. Heavy loads, especially things like comforters, are more likely to become unbalanced than small loads. If you do a lot of heavy loads, you should consider a heavy duty/large capacity washer when it comes time to replace your current unit. A washer must be level both from side to side as well as from front to back. Washing machines have adjustable feet to enable you to level them. See your manual on how to level your washing machine.The outer tub/basket, is supported by springs, pistons or counterweights to keep it balanced. The weight of all that water in a wash load requires a powerful balancing mechanism. If the balancing system becomes detached from one or more points, it will not be able to balance the load properly. Furthermore, even if everything appears to be in place, as the appliance ages, the springs or pistons/shock absorbers, may begin to wear out and not support as much weigh as needed.

In order to check properly for internal issues,unplug the washer and open the cabinet. Because of the variety of balancing mechanisms, you will have to inspect your machine to determine how it is balanced. Once you discover the mechanism, then inspect it for integrity. In the case of old parts that appear to be in working order, you may not be able to tell if they need to be replaced. They may be weak but appear to be in good condition. If no other solution resolves the problem, then replacing the balancing springs or other moving support parts may be the best action.Another common cause for excessive movement, or rocking, is the floor on which the washer sits. The washer is heavy and even more so when filled with water. Any floor, other than a concrete slab, will tend to pick up and amplify the vibrations from the machine.There are a couple things you can try. If you have access to the joists under the floor, you may be able to beef up the support. Another thing to try is placing a large sheet of plywood under the washer. It should be 3/4" or even 1" thick and as large as possible to distribute the weight. Use a sheet big enough for both the washer and dryer to sit on. If possible fasten the plywood to the existing floor.
