How to Sanitize a Sub-Zero Ice Maker

Immediate sanitizing of the Sub-Zero ice maker is recommended after the cleaning process is complete. To remove bacteria, mold, and mildew, Sub-Zero recommends using their Sub-Zero Ice Maker Sanitizer.

To Sanitize the Ice Maker:

  1. Begin by pressing the Clean button again.
  2. Measure 1 tablespoon of the undiluted Sub-Zero Ice Maker Sanitizer
  3. When the clean light begins to flash, pour the sanitizer into the spray area.
  4. Similar to the cleaning process, the sanitizing process will automatically begin. The ice maker will run a sanitizing cycle for ten minutes, then will run eight rinse cycles.
  5. Step number 4 can take up to 30 minutes. While the unit is sanitizing, mix 1 teaspoon of sanitizer with six cups of warm water. Apply this dilution to the ice bin using a soft cloth.
  6. Rinse your soft cloth thoroughly in warm water. Wipe down the interior of the ice bin, concentrating on removing any mineral build-up or debris.
  7. Once the sanitizing process is completed, the clean light will stop blinking, and your Sub-Zero ice maker is ready to make fresh ice once again!

How Often to Clean an Ice Machine

Even with regular cleanings, over time your Sub-Zero ice maker may develop mineral deposits or a bacterial film. Depending on how often you use your machine and the quality of your water, we recommend deep cleaning your machine every three to six months.
