Small cubes usually mean the ice mold is not receiving the expected amount of water or the fill is being interrupted.

Possible causes

  • Restricted or overdue water filter
  • Kinked supply line or low household water pressure
  • Frozen or misaligned fill tube
  • Restricted self-piercing saddle valve
  • Water inlet valve or ice maker fill problem
  • Ice maker not level

Check for obvious line kinks and follow the manufacturer’s filter instructions. Water-valve and timed-fill diagnosis usually requires model-specific testing.
