Ensure that the refrigerator/freezer is properly connected to a power supply and water lines.
Open the water valve completely. Closed or partially shut water valves will prevent proper flow to the ice maker and result in reduced ice production and supply.
Check for a pinched water line. A pinched water line causes increased pressure when the fill valve is activated, causing leaks.
Ensure there are no obstacles or blockages at the water valve that may prevent water from entering the ice maker, thereby preventing the ice maker from working correctly.
