Thanks to Owner-Manuals.com! This manual was exactly what I needed. As Amana was purchased by Maytag and later by Whirlpool, there was no way to receive it from their websites. I was lucky to find this resource.
A comprehensive Operating and Service Manual. All schematics are complete and easy to read. The PCB drawings and complete parts list are very helpful. I would definitely recommend this manual.

Water inlet
A 1.35m long pressure hose is supplied with the appliance. If a longer inlet hose is required, only hoses from the manufacturer are to be used. Service Force stocks hose kits of different lengths.

Sealing rings are either inserted in the plastic nuts of the threaded hose fitting or are included as spare parts. Do not use any other sealing rings. Important! All threaded hose fittings must only be tightened by hand. 1. Connect the hose with the right-angle connector to the machine. Important! Do not position the inlet hose vertically downwards. Position it to the right or the left as shown in the illustration.
2. Connect the hose with the straight connector to a water tap with an R ¾ (inch) screw thread. 3. Slowly turn on the tap and check that all connections are watertight.
