E9 displayed; unit may overfill or underfill with water, causing poor ice formation or overflow.

Safety first: Unplug the unit and shut off the water supply (for plumbed-in NewAir ice makers) before servicing the inlet system.

Steps to address E9:

• Check water supply: Ensure the supply valve is fully open and that the inlet hose is not kinked.
• Inspect inlet screen: Disconnect the inlet hose and check the small filter screen at the valve for sediment. Clean if clogged.
• Observe fill behavior: With panels removed and water supply on, briefly power the unit and watch the reservoir during fill. If water continues flowing after the fill stage, the valve may be sticking open.
• Test the inlet valve: Use a meter to confirm the valve coil has proper resistance. If the coil is open or shorted, replace the valve.
• Check flow meter (if present): Some models use a small flow sensor in-line. Inspect for debris and ensure the connector is secure.
• Replace faulty components: Install a new inlet valve or flow meter as needed, then clear the code by power-cycling.

Warning: Always check for leaks after reconnecting water lines.
