Ice cubes are too small, hollow, or irregularly shaped.

Safety: Turn off water and unplug the unit.

Steps:

• Clean inlet filter: Remove and rinse the mesh filter at the water inlet valve.
• Check water pressure: Ensure the supply line delivers strong flow. Avoid self-piercing saddle valves; use a proper tee connection.
• Descale tray and sensors: Remove the ice tray and clean with warm water and food-safe descaler to remove limescale from surfaces and level probes.

After reassembly, restore water and power and monitor cube size over several cycles.
