How to Fix / Troubleshooting
Safety: Disconnect power before accessing the ice mold assembly.

- Clean mold: Descale the mold with a manufacturer-approved cleaner to ensure even heat transfer and water distribution.
- Test heater: Locate the mold heater leads and test for continuity. Replace the mold heater if open.
