Question:
Water in door of Amana reefer sprays all over when try to use. Any clues?

Answer: My real guess is something is stuck in the tube where the water exits, causing it to spray, perhaps even a sediment build up from hard water. AFAIK the valve controlling the water flow is at the rear of the refrig, so no danger of being shocked while probing the nozzle.

Now I need to figure out how to get at the line tip. There must be a way without standing on my head. It is hard to even see. So far my helper has not found the papers for the unit. Persevere

probably hard water deposits. You might want to remove the water tip and clean it well. If you have hard or lousy water in your area, put a filter on your water line going to the fridge.
