Ice cubes are very small, hollow, or melt quickly in the basket.

Safety first: Unplug the unit before cleaning the evaporator or internal parts.

• Use colder water: Fill the reservoir with cold water from the refrigerator rather than warm tap water.
• Lower room temperature: Move the unit to a cooler room away from heat sources.
• Descale evaporator: Run a cleaning cycle with a vinegar solution or manually wipe the evaporator fingers with a soft cloth soaked in descaler. Scale acts as insulation and reduces ice size.
• Allow full cycles: Let the unit run for several cycles. Many Igloo ice makers produce smaller cubes initially that increase in size after the system stabilizes.
• Check for fan and compressor issues: If ice remains small despite cleaning and good conditions, inspect the condenser fan and compressor performance as described in other entries.
