We have an old front-loading Maytag Neptune washing machine. The bearings are going bad. I'm looking into having someone swap the bearings out for me, but also considering getting a new machine.
I found that Puget Sound Energy has a program where they will give customers a free washing machine under some circumstances! But here's the weird part: they will give a free front-loader only if it will be installed at ground level or in a basement; for upstairs they will only give a top-loader. The relevant quote:
You'll receive a free ENERGY STAR qualified clothes washer that fits in the same spot as your old one. If your new washer will be installed on the first-floor or basement level, you can choose a front-load model. Or you can choose a top-load washer for any level of your home.
Why would PSE have a policy like this?
P.S. Our washer/dryer closet is upstairs, by the bedrooms. We love the front-loader so I'd rather not accept a top-loader even if it's free. But I am really wondering if there is something I ought to worry about if I'm picking a new machine.
EDIT: I have accepted an answer. I am certain that vibration is the issue. I will just be sure to buy a washer with low vibration. One brand of washer actually has a "Second-Floor Guarantee" and I might buy that brand.
Thanks to all who answered.
