Visible mold, slime, or heavy scale buildup inside the ice maker.

Safety: Unplug the unit. Wear gloves and avoid inhaling any mold spores.

• Disassemble removable parts: Remove the ice basket, water reservoir (if removable), water distributor tray, and any removable covers.
• Deep clean: Soak removable parts in warm water with mild detergent, then scrub with a soft brush. Use an approved ice maker cleaner or diluted bleach solution (per manufacturer) for severe mold, then rinse thoroughly.
• Clean internal surfaces: Wipe internal plastic and metal surfaces with a cloth soaked in cleaning solution, then rinse with clean water.
• Descale: Run a descaling cycle if supported, or manually circulate a descaling solution through the water path, then flush with multiple fresh water cycles.
• Maintenance schedule: Implement a regular cleaning schedule (e.g., monthly) to prevent recurrence.
