 The point we've heard sometimes of my ice maker doesn't make as much ice as it used to. Or the water coming out of the door is taking a lot of it to fill up my glass. Well, the reason for that is, in all probability, as the water comes in through here, it goes through a screen. It filters out the water. Depending on how hard your water is, if you've got hard or soft water, depends on how hard this mineral is plugged to a screen up. And as more and more minerals build up on the screen, less and less water can go through it. Before the water is coming into your ice maker or coming out of your door, it's reduced.
