648PRO Series with Service and Ice Flashing

Cause:

  • Water valve solenoid for the ice maker was energized too long
  • Ice maker disabled to prevent water from leaking or water damage

Core Issue:

  • How to fix Service Ice flashing
  • No ice is being made and Service Ice is flashing
  • How to distinguish between "Service" flashing and "Service Ice" flashing on a Sub-Zero

Steps to Verify Issue:

If both "Service" and "Ice" are flashing:

  1. Turn the unit off for 10 seconds.
  2. Turn unit back on.
    • On the electronic control panel, press On/Off or Power button to turn the unit on and off.
  3. If only "Service" is flashing and "Ice" is solid, see Service Flashing.
  4. If this recurs frequently in a short time, contact Factory Certified Service. If this recurs after six months or longer, this can be reset following the above steps.
    • Ice production resumes shortly after this reset.

Refer to No Ice Production for additional ice maker troubleshooting.
