If your Whirlpool refrigerator ice is dirty, the most likely culprit is the water supply tube to the ice maker—stagnant or disconnected tubing can discolor when water sits unused for months, and replacing that tube usually clears the problem. Next, check the ice maker tray itself; a worn or corroded coating can flake into the ice and produce bits or discoloration, so replacing the ice maker assembly or tray often fixes dirty ice. Less commonly, dirty municipal water from a flushed hydrant or broken main can send sediment into your home plumbing; run a faucet until the water clears and discard the old ice before making new batches. Finally, residue from an old water filter can cloud or stain ice, so swap filters every six months and change a suspect filter right away.

01 - Whirlpool 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.
