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.

Washer Operating Instructions
The drawings in this book may vary slightly from your Thin Twin model. They are designed to show the different features of all the models covered by this book. NOTE: Your model may not include all the features shown.
Starting your washer
Be sure to measure and add detergent, then place a sorted load in the washer before starting it. 1. Select a load size l Position the Load Size Selector at the setting that describes the size of load you want to wash. l The selector can be set anywhere on or between EX SMALL (a few small items) and EX LARGE (a full load). l To change the water level after the washer has started to fill, turn the selector to RESET then to the desired water level. NOTE: For best washing results, items should move freely in the washer. Do not overload the washer or choose a water level that is too low for your wash load. For best results with permanent press clothes, use the EX LARGE water level. Reduce wash time when using EX SMALL or SMALL water level settings. Loads with only a few small Items need less wash time for best results. 2. Select water temperature l Match the water temperature to the type of fabric and soils being washed. l The top temperature is the wash selection and the bottom temperature is the rinse selection. NOTE: Use warm wash water with the PERMANENT PRESS or KNITS GENTLE Cycles. For heavily soiled permanent press or knit clothes, pre-wash or pre-soak before washing in warm water. ALWAYS use cold rinse water for permanent press fabrics.
