The Neptune line was Maytag's first high-efficiency front-loading washer/dryer line. Introduced in 1997, it was discontinued in favor of the Bravos line in 2007, when 250,000 Neptune front-loading washers were recalled for repairs due to a potential fire hazard. The models recalled by the U.S. Consumer Product Safety Commission were the MAH8700 and MAH9700 stackable units. Apart from the flat-top front loaders, a model with a raised back panel and slanted front edge was sold, but these Neptune models are not stackable. Model MAH2400 compact washer and MDE2400 compact dryer are still sold under the Neptune name in Canada. The same models are still sold in the U.S., minus the Neptune moniker, and can be stacked.
Stacking kits for the 24-inch compact and 27-inch standard flat-top front loaders are available from Maytag, as well as from online appliance dealers. They consist of a bracket installed on top of the washing machine with double-sided tape and screws. The upper side of the bracket is molded to cradle the bottom of the dryer once it is lifted into place and set into the bracket.
Neptune Super Stack
Maytag also produced a Neptune model called the Super Stack that was sold as a one-piece, stacked unit. The Neptune Super Stack, model 2000AYW, came in gas or electric and was a full-sized, 27-inch unit with a high-efficiency washer on the bottom and dryer on top. The set is discontinued, but still available from some online retailers.
Before you decide to stack your Neptune front loader, ensure you have adequate space. There needs to be a minimum of 8 inches between the top of the stacked dryer and the ceiling. There must also be adequate space behind gas units to allow air circulation and the venting system. Also, allow several feet in front of the stacked units for loading and unloading, and consider whether you will be comfortable lifting wet clothing up into the raised dryer unit.
