The worst thing about the Neptunes was that they severely shook customers' faith in Maytag when Maytag failed to honor warranties on Neptunes' circuit boards that were just over the warranty period when there was trouble related to the wax motor door lock or something related to it that fried the board. Maytag forced customers to pay for replacement of the board. I think it led to a court case. The suspension in the Neptune was wonky, too, and the tub had a propensity to fish tail with unbalanced loads. There was also strange software whereby Max Extract offered fewer attempts at balancing than the regular spin option.
Maytag's conservatism was responsible for a lot of their problems, like sticking with their small tub machines way too long before offering their only slightly larger tall tub machines that were still small in comparison to large capacity machines offered by other manufacturers. You can only get by so long by having Consumer Reports lie about the load capacity of the 16 gallon tub and, before that, the 12 gallon tub, all with the agitator designed for the large tub of the wringer washers. The argument could be made that Maytag's downfall started with their poorly designed automatics that were largely sold on the basis of the reputation of the Maytag conventional washers which had excellent washing action of standard size loads. Many Maytag owners, after having experience using another brand of automatic, did not buy a second Maytag.
I still remember the 1974, I think, issue of Consumer Reports with a large capacity Whirlpool washer and a standard tub Maytag on the cover. The Whirlpool washer had two laundry baskets in front of it while the Maytag had three and big print explaining that this was to show that the Maytag took three loads to wash what the Whirlpool could wash in two. Whoever did the purchasing for that washer report sure goofed up by buying the small tub Maytag. Earlier, Consumer Reports did a rating of one speed washing machines and the Maytag Fabric Matic ruined casement weave curtains washed on the Delicate Cycle. It was needless self injury to keep offering single speed machines when Sears had two speed machines far down in their line and two speed motors were not that much more expensive than single speed motors, but Maytag wanted customers who wanted a Maytag to pay for every feature.
