Refrigerator - Black Particles In The Water

Many Refrigerators feature a water filter that filters the water for the icemaker as well as water dispenser. If the water filter is newly installed or just recently changed, black particles may be noticed in the water and/or ice cubes. These black particles are fine carbon particles left over from the water filter manufacturing process. While these carbon particulates are harmless, you may want to eliminate them from the water system.
 

Flushing Black Particles From the Refrigerator Water System

You may want to check the Owner's Manual for the Refrigerator you own regarding specific instructions when changing the water filter. Also, replacement water filters typically come with instructions for changing the filter.
 
  • We recommend that two to three gallons of water be dispensed from the water dispenser on the Refrigerator to flush carbon particulates from the filter and water distribution system.
  • If you are not able to measure in gallons of water, purging the system for approximately five minutes should eliminate the particles.
  • For a Refrigerator model that has a filter for the icemaker only (no chilled water dispenser), simply discard the first few batches of ice cubes should black particles appear.
