It's tough to fix this inherent weakness, and it's the number one reason (of several) that I can't recommend these machines. 

Here's the problem: When you hang 40-50 pounds of water, laundry, and basket out on the end of a rotating shaft supported by bearings pressed into plastic, you have a mechanical system that just can't survive very long. 

Other problems include leakage at the seam between the two (plastic) tank halves, basket pulley failure, usually resulting in tub wear-through and leaks, and motor (3 phase) controller circuit board failures, just to name a few of the most common. 

Considering one of these washers can cost up to $1400, 5-7 years just isn't a sound investment. And we won't even go into the electronics problems we have with them out here in the 'boonies' from electrical power that's anything but 'clean' and reliable. Or voltage 'spikes' from nearby lightning strikes... 

There may be a bright spot on the horizon, but it's too early for me to tell you if it'll dawn or not. A company in Groveport, Ohio, Staber Corp, entered the residential front loader market a few years ago, and their machines look promising. 

They address the bearing problems by supporting their wash tub with bearings in both front and rear - a major improvement.

Technically not front-loaders (they load from the top), these are what we call 'horizontal axis' machines, because the tub rotates horizontally like a typical FL, and your dryer. Unique.

Even though it appears they're using electronics driving a 3 phase motor like the others, this is one to watch. Cost is around $1200, though - still an awful lot of money to do your laundry, IMO. But check
