An old filter that needs replacement
Eventually, fridge filters stop doing their job, and begin letting unwanted substances through and into the fridge’s water dispenser and ice maker. This can quickly lead to grayish ice cubes. Most manufacturers recommend fridge filter replacement roughly every six months depending on the water volume used.
How Do I Clean Dirty Ice?
If your fridge has started spitting out gray ice cubes, cleaning your ice bin is the first and easiest thing to try. Unplug the refrigerator, then remove all the ice from the ice bin in the freezer. Take the ice bin out, then thoroughly wash it with soap and water. If lots of dirt comes off, chances are you’ve discovered the reason for your gray ice. Dry the ice bin carefully, then replace it in the fridge and plug the fridge back in. When the ice maker has a chance to make a new batch of ice cubes, check them out. If your ice bin was dirty, the new batch of ice will now be clean and normal in color.
