Front-load washers are making their way into more and more of our homes each and every day. These washers have many advantages over their old, top-loading ancestors, such as greater water and energy efficiency. One of the reasons that laundry washed in a front loader is so much more energy efficient is because of the tremendous spin speeds that these washers can reach. Spin cycles on many front load washer models can approach 1300 RPM. These high speed spins result in more water being extracted from the laundry which, in turn, results in less time and energy needed for drying.
The downside of all this super fast spinning laundry is an increase in machine vibration. It used to be that most people would install the old washer and dryer down in the basement where they would bounce and bang away hour after hour and not bother anyone. Now, in more and more homes, people want the laundry room to be close and convenient to areas where they spend most of their time. Usually this means moving the washer and dryer out of the basement and into the main living areas. As a result, people want their machines to be as quiet as possible.
This Washington Post article has some very good advice on how to help eliminate excessive noise and vibration from all types of washers, both front and top load styles.
