If your refrigerator is making dirty or discolored ice, start by checking the water supply tubing to the ice maker — sitting unused or disconnected for months can let mineral or organic residues build up and stain the ice, so replacing the water tubing is often the first and simplest fix. Next, inspect the ice maker assembly and tray; a flaking coating or corroded tray will shed bits into the ice and means the icemaker should be replaced. Less commonly, dirty municipal water from a flushed hydrant or broken main can temporarily discolor ice; discard old cubes and run a nearby faucet until the water clears before letting the ice maker make new ice. Finally, an overdue or degraded water filter can release residue, so swap the filter every six months.

01 - Modern Maid 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.
