In the mid-90's, I rented a house on Beaver Island, MI that had WW front loader and matching dryer. They were obv. meant to be stacked, as they had no tops and the controls were on the front. A piece of plywood was across the top of both of them side-by-side. It was the home of an old heiress who had gone to assisted living. The house had been built in the mid-70's, and I assume the white laundry pair was of that vintage. She probably only had her help do a few loads a week. Pretty modest house, just 3 small beds and a bath and a half.
I'd had NO experience with a front loader, and had my doubts about the cleaning ability. Because I heated with wood, and am an electrician, I sometimes I really had some filthy work clothes. I recall being surprised that it cleaned them pretty well. I just used whatever detergent was cheap and used about 1/3 of what was called for in a top loader. In the 3 years I lived there, they worked fine. Did notice some rust beginning to form under the opening, so suspect the boot may have been wearing out. Do recall that when it went into spin, you KNEW it no matter where in the house you were. Prob. didn't help that they were in the middle of the house in a closet under the stairs. Went back a few years ago, and they'd been replaced by they generic top load washer with dryer above combo.
I'd learned my lesson by using Palmolive DISH soap in the dishwasher at the college apartment... NEVER have you seen so many suds oozing out of a machine, except perhaps an old comedy movie. SO, I' d learned to be careful to follow instructions with detergents and never had over-sudsing with the washer!
Amazed the design lasted so long, and that more front loaders weren't available. Always found them interesting as they were so rare. Worked in a few houses on the island that had WW front loaders of the same era. Some were summer homes, so didn't see much use, and thus had longer lives.
Seems like there was some prejudice against FLs in the 60's, 70's 80's; folks felt they were more complex, not as durable, didn't cleanas well, etc.
