Panthera,
Well, for what it's worth, we didn't just "put up with it". Lawyers got wind of the problem and Maytag was slapped with a successful class-action lawsuit. The upshot is that Maytag not only offered free upgrade kits for the worst offenders, but eventually offered cash or credit settlements to those who had to pay for similar repairs.
And, happy to say, the last round of Neptunes (7500 and 6500, maybe the 5500b) eventually had upgraded components (motor/motor control on mine) as well as solenoids instead of wax motors, etc, that pretty much eliminated the many problems (knock on wood).
Add to that, the solid door Neptune is the only front load washer I know of with a reversible door, and save the Speed Queen FL, is the only extra large capacity FL in the US that can have the washer door hinged on the right. The Speed Queen is a mixed bag - with ridiculously short wash times (about 10 minutes max) that may make it suitable for laundromats but not the home, coupled with solid, servicable construction. No other 27 inch wide washer will fit in my laundry closet. The only other option is a top loader, or a 24" Euro washer with associated issues of capacity and cost.
My Neptune 7500 was one of the earlist of that model produced, and it had a number of problems hit when it neared the 3 year mark - most notably a toasted motor/motor control board, and a cracked spinner support. The replacement motor was an upgrade to a more powerful design that also required a new controller. I noticed some intermittant failures after that work and Maytag replaced the main control board as well, which was also an upgrade to latest firmware. The spinner support issue was perplexing - it was a clicking or knocking sound when tumbling heavy loads of towels. At first I thought it was a belt issue, but the Maytag man diagnosed it correctly as a cracked support, and said it was good that it got replaced before it failed catastrophically during a high speed spin. All repairs were done for free under the extended service agreement I purchased, and two years later it appears that these pretty much resolved any reliability issues for the foreseeable future. In other words, no problems since then, and the washer gets regular heavy use.
