- Copper corrosion in the water line supplying the refrigerator causes blue or green ice
- Calcium deposits in water cause white flecks in ice cubes especially as it melts
- When water freezes and thaws, the minerals in it concentrate and the thaw cycle contributes to this
- Ice shrinks as it evaporates, leaving this concentrated mineral ‘residue’
- Calcium deposits are not visible in liquid water. Make a batch of ice in an ice tray using water from a different tap to test home water supply
- Calcium deposits may just be in the water line to the unit. Using the filter in the unit (Classic (formerly Built-In) and Designer (formerly Integrated)) or adding a filter to the water line can help reduce calcium deposits
- Cloudy ice is the result of mineral deposits in the water that appears as the ice dries out
- Why are ice cubes green?
- Why are ice cubes blue?
- What to do when ice maker makes blue or green ice cubes?
- Why are there white flecks in the ice cubes?

- If installed, verify the in-line water filter is not expired. See also:
- Adding an in-line water filter (available at most home improvement stores) may reduce or eliminate discoloration.
- Refer to the product installation guide for water pressure specifications.
- Discontinue use of ice.
- Consult with a local plumber.
- Plumbers may clear water lines and replace corroded plumbing fixtures for blue/green ice.
- Plumbers may suggest the best kind of filter for white sediment in water.
- For any other color ice cubes, contact a plumber as this is a water or water line issue.
- For black flecks in ice, see Black Flecks in Ice Cubes.
