Ice cubes are hollow, small, or clumped together.

Safety first: Turn off water supply before adjusting valves.

• Check pressure: Ensure the shutoff valve to the refrigerator is fully open and not a self-piercing saddle valve (which can restrict flow). Replace with a proper drill-type valve if needed.
• Replace filter: Install a new GE filter to restore flow.
• Inspect line: Look for kinks in the supply line behind the refrigerator.
• Replace valve: If pressure is good but ice fill remains low, replace the dual water inlet valve.
