How to Fix / Troubleshooting

Safety: Unplug the unit before cleaning. Wear gloves if using cleaners.

Steps to remove buildup:

  • Disassemble removable parts: Take out the ice bin, scoop, and any removable trays or filters.
  • Wash components: Clean with warm soapy water, then rinse and dry.
  • Descale interior: Use a food-safe ice machine cleaner or a 1:1 vinegar-water solution to scrub the reservoir, evaporator, and water paths. Avoid abrasive tools that can damage surfaces.
  • Flush thoroughly: Rinse multiple times with clean water and run at least one full batch of ice to discard.
  • Improve drainage: Ensure the drain is clear so water does not stagnate.
