A:Answer Auto fill is a hands free way to fill a container with water. You place the cup on the dispenser tray, press the auto fill button and, voila, the cup is automatically filled with water and it stops about an inch below the top of the container. This is really handy when you are doing multiple things, for instance setting the table, and you can press auto fill, go back to setting the table, and come back to a glass ready and filled.
