Sub-Zero Ice Maker Water Fill Adjustment


  • Can the water fill level on an ice maker be adjusted?
  • How to increase or decrease the amount of water into the ice maker
  • Too much or too little water enters the ice maker ice cube mold


Ice maker water fill adjustments vary by ice maker model.

  • Older 500, 600, and 700 Series models have a fill adjustment, and most are made on the ice maker itself.
  • Sub-Zero recommends that any ice maker adjustment be completed by a service technician. Contact Factory Certified Service to schedule an appointment for repair.

Classic (BI) and Designer (formerly Integrated) units do not have a water fill adjustment.

  • In Classic units, water fill volume is adjusted automatically based on water intake through the flowmeter.
