How to Fix / Troubleshooting

Safety first: Unplug the unit and shut off water before cleaning. Discard all existing ice.

Step-by-step cleaning:

  • 1. Empty and remove bin: Take out the ice storage bin and wash it with warm water and mild detergent. Rinse and dry.
  • 2. Clean reservoir: Drain the water reservoir and scrub with a soft brush and a mixture of water and food-safe sanitizer or vinegar. Rinse thoroughly.
  • 3. Descale system: Run a cleaning cycle using an IceKing-approved ice maker cleaner to remove scale and biofilm from internal lines.
  • 4. Wipe interior: Clean all interior surfaces with a mild bleach solution (per manufacturer guidance), then rinse and dry.
  • 5. Replace filters: If your model has an internal water filter, replace it.

When to call a technician: If odor persists after thorough cleaning, internal insulation or inaccessible areas may be contaminated and require professional service.
