If your refrigerator is making dirty or discolored ice, the most likely culprit is the water supply tubing to the ice maker—tubing that sat with water in it for months or was disconnected can become stained and leave residue in the ice. If the rest of the house has clear water and you already replaced the filter, swapping the water supply tube will often solve the problem. If you find flakes or chunks in the ice, the icemaker tray coating may be corroded and flaking off, so replacing the ice maker assembly is usually the next step. Less commonly, a recent hydrant flush or broken water main can send dirty water into your home; run the kitchen faucet and discard ice until the water clears. Old or overdue water filters can also shed residue, so replace filters every six months for best results.

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.
