How to Fix / Troubleshooting
Safety first: Unplug the unit and shut off water before cleaning. Do not mix cleaning chemicals.
- Discard old ice: Empty the ice bin completely and discard any ice with off-odors.
- Clean the interior: Wash the bin, reservoir, and accessible water-contact surfaces with a mild dish soap solution, then rinse thoroughly.
- Descale if needed: Use an ice maker-safe descaling solution per EdgeStar instructions to remove mineral buildup from the evaporator and water lines.
- Flush the system: After cleaning, run at least 2–3 full ice cycles and discard the ice to flush any residual cleaner.
- Check water source: If taste issues persist, consider adding a water filter upstream or using a different water source.
