600 Series with Service and Ice Flashing


  • How to fix Service Ice flashing on a 600 Series unit
  • No ice made and Service Ice flashing
  • Difference between "SERVICE" flashing and "SERVICE ICE" flashing on a 600 Series unit


  • Water valve solenoid energized too long


If both "SERVICE" and "ICE" are flashing:

  1. Turn the unit off for 10 seconds.
  2. Turn the unit back on.
  3. If only "SERVICE" is flashing and "ICE" is solid, see Sub-Zero with "Service" Flashing.
  4. If this recurs frequently in a short time, contact Factory Certified Service.
  5. If this recurs after six months or longer, this can be reset following the above steps.
  6. Ice production resumes shortly after this reset.

Refer to No Ice Production for additional ice maker troubleshooting.

If these steps do not resolve the issue, no further troubleshooting advice is available. Contact Factory Certified Service to schedule an appointment for repair.
