If your refrigerator ice is coming out discolored or with flakes and chunks, the most likely culprit is the water supply tubing to the ice maker—stagnant water in a disconnected or unused tube can discolor over months, so replacing the supply tube often fixes dirty ice. Next most common is a failing ice maker assembly: a corroded or worn coating on the ice tray can flake off and end up in the cubes, so replacing the ice maker is the right ice maker repair in that case. Less commonly, dirty water from a flushed fire hydrant or broken main can temporarily taint your ice; discard the old ice and run a kitchen faucet until the water clears before making new ice. Finally, residue from an old water filter can contribute, so change filters every six months.

01 - U-Line Refrigerator Water Supply Tube
During normal use the water supply tubes will have water flowing through them keeping them clean. If the water supply gets disconnected or water is left in the tube and not used for 6 to 12 months, it can become discolored. If the water at the other faucets in the house is ok and you have replaced the water filter you may need to replace the water tubing to the ice maker to resolve the issue.

If the icemaker tray has a coating, the coating may be wearing off. If you are getting pieces or chunks of material stuck in the ice, check the ice maker tray. If the coating on the tray is corroded and flaking off, replace the icemaker.
A fire hydrant that was flushed or a broken water main can cause dirty water to enter the home. Since the ice maker uses the same water supplied to the kitchen or bathroom faucets, dirty water can discolor the ice. Discard the old ice and run the water for awhile at the kitchen or bathroom faucet until the water clears up before having the ice maker make new ice.

If the ice being dispensed is dirty, it's possible that residue from an old water filter is getting into the water being supplied to the ice maker. Water filters should be replaced every six months for optimum water filtration.
