Sub-Zero Dirty Water from Water Dispenser

Topics:

  • Water coming from dispenser is dirty
  • Water contains sediment when dispensed
  • Water is discolored or cloudy

Cause:

  • Copper corrosion in home water line supplying refrigerator
  • Water filter not being used or is dirty
  • Construction around home caused sediment to enter water supply

Troubleshooting:

  1. Verify no service messages, icons, or error codes appear.
  2. For Classic (BI) and Designer (IT, IC) models, make sure the water filter is not expired.
    • For other models, addition of an in-line water filter may reduce discoloration.
    • If it is already in place, make sure the in-line water filter is not expired.

  4. Consult with a local plumber to clean the water line leading to the unit.
    • A plumber can also purge the home water supply line.
