Older Amana washers which show leakage at the main seal require a
certain amount of skill and special tools for repair. I would suggest
against trying this yourself, if only because of the frustration
factor and learning curve.
Newer Amana washers are rebranded Maytags, which are actually based on
Norge a Norge design. These also require specialized tools.
Maytag wash purchased by Whirlpool recently. New Maytags, perhaps
under its various brand names, will probably be badge engineered
Whirlpool direct drive models. In other words, if you put the Amana,
Maytag, Kenmore, and Whirlpool models side by side, the inherent
platform and design will be the same, although styling and features
will differ by model.
