Ice maker produces ice, but cubes are very small or hollow and melt quickly.

Safety: Unplug the unit before cleaning internal components.

Steps:

• Check water level: Ensure the reservoir is filled to the correct level. Refill with fresh, cold water.
• Descale evaporator: Drain the unit and fill the reservoir with a mixture of water and food-safe descaler or white vinegar (per Caso instructions). Run a cleaning cycle if available, or let the solution sit in contact with the evaporator plate for 20–30 minutes, then scrub gently with a soft brush and rinse thoroughly.
• Clean condenser: Remove dust from the condenser coil and ensure the fan is working properly to improve cooling efficiency.
• Improve ambient conditions: Move the ice maker to a cooler room away from direct sunlight and heat sources.
• Monitor results: After cleaning and relocating, run several cycles and check cube size. If still very small, the refrigeration system may be weak and require professional diagnosis.
