How to Fix / Troubleshooting

Safety first: Unplug the unit before cleaning. Discard all existing ice.

  • Drain and clean: Open the drain plug and empty the reservoir. Wash the reservoir and ice basket with warm water and mild dish soap. Rinse thoroughly.
  • Descale: Run a cleaning cycle (if available) or manually fill the reservoir with a 1:1 mixture of white vinegar and water. Let it circulate for 10–15 minutes, then drain and rinse several times with clean water.
  • Flush lines: Make several batches of ice and discard them to flush internal lines.
  • Use filtered water: Use fresh, filtered, or bottled water to improve taste and reduce mineral buildup.
