Ha! The early Maytag Neptune washer was horrible. My clothes always smelled like mildew. It was disgusting. Started less than three weeks after the warranty expired. Repairman kept my washer for a month, could not get the part(s) to repair. Finally, I contacted Maytag, & negotiated a salvage payout for the useless washer. Two weeks later, learned about a class action lawsuit against those early Neptunes. Maytag had already paid me $50 more than the lawsuit settlement.
I’ve heard those complaints about the Neptunes, but we’ve never noticed any musty or mildewy smell. Maybe we have a Gen 2 machine. A repairman says those old Neptunes were designed well and hardly ever fail.
