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

Safety: Turn off water and disconnect power before working on water lines.

• Check water pressure: Ensure household water pressure is adequate. If other faucets are weak, consult a plumber.
• Replace filter: Install a new OEM Bosch filter and flush several liters of water through the system.
• Inspect water line: Look for kinks or sharp bends in the line behind the refrigerator and inside the cabinet leading to the ice maker. Straighten or replace as needed.
• Clean inlet screen: Remove the water line at the Bosch inlet valve and clean the mesh screen of debris.
• Test ice size: After corrections, allow several cycles and recheck cube size.
