Ice maker runs but produces very small or thin ice cubes.

Safety first: Unplug the unit and close the water supply before disconnecting hoses.

Steps to improve cube size:

• Check water pressure: Ensure the supply line delivers adequate pressure (typically 1–10 bar). If pressure is low, correct plumbing issues or use a larger supply line.
• Clean inlet valve screen: Remove the supply hose and clean the mesh filter at the water inlet valve to restore full flow.
• Inspect water level sensor: Some SMEG models use a float or probe in the sump. Clean mineral deposits from the sensor so it can accurately detect water level.
• Run a descaling cycle: Mineral buildup on the evaporator plate can cause early ice release. Descale the system using SMEG-approved cleaner.
