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.
Great to be able to set channels again, on an old but stoll fine working TV

Adjusting the height of the upper basket
If washing very large plates you can load them in the lower basket after moving the upper basket to the higher position.
Maximum height of the dishes in: upper basket With upper basket raised With upper basket lowered 20 cm 24 cm lower basket 31 cm 27 cm
IMPORTANT! When the basket is in the higher position you will not be able to use the cup rack.
Move the front runner stops (A) of the upper basket outwards and slide the basket out.
Refit the basket in the higher position and replace the stops (A) in their original position.
