+25 grains. Damn, might as well wheel in two water heaters every time you buy them out there. Just choosing sani heat or temp boost is enough to produce the milky stains of flash drying in severe hard water areas. Where I was originally from, the water hardness would vary depending on which reservoir they were drawing from upstate. Usually between 10 and 18 grains. You might want to check out the use and care book on the unit. Below is what it states on line for that unit. They have actually softened the wording. It used to say Amana is not responsible for poor cleaning results in area's of water hardness over 15 grains. Below that is a description of flash drying from the web. I have a lot of info on hard water and it's effects as well if you would like it faxed. I started to build a folder of information concerning it because it became more of a problem. Another thing to consider on the grit deposits is water fill. Most of my techs will tell me its fine! But when I make them take the kick-plate off and see if the float has caused the fill to stop or the board timing it out, 9 times out of 10 on grit complaints it's the board. They changed valves on these units to allow a greater GPM rate because of it. New board provide a 10 second longer fill as well. Good luck in what you find.  


Recommended Amount

Too little detergent results in poor cleaning, hard water filming/spotting and poor drying. Too much detergent can cause permanent etching/cloudiness. Suds can cause the dishwasher to overflow. Measure the detergent carefully and use only detergents designed for use in a dishwasher. Less detergent is needed in soft water. Try another brand of detergent if sudsing continues. The amount of detergent to use is determined by the hardness of the water and soil level of the load. Refer to the following chart for detergent usage recommendations.

In extremely hard water conditions (13 grains per gallon or more*), it is difficult to achieve good results with any dishwasher. A mechanical water softener may be necessary to improve water quality, detergent effectiveness, and protect the dishwasher parts from the damage that hard water can cause.

   ***Always purge the hot water at the sink until it is hot just before running the dishwasher. This will ensure the first fill is hot. Also, check to make sure that your hot water heater is set between 120-125 degrees. Most units are shipped turned way down. Keep in mind that hotter is not better. Any hotter with these new dishwashers and you get what is called flash drying. This is when the environment in the dishwasher is so hot that after the final rinse, instead of the water running off the glass taking with it all its impurities, it is instantly baked on.
