Display shows E9 and the ice maker (if fitted) does not produce ice; sometimes water may not dispense.

Safety first: Unplug the refrigerator and shut off the water supply before working on the ice maker.

Steps:

• 1. Inspect the ice maker: Remove the ice bucket and check for large ice clumps or jammed cubes blocking the ejector arm. Clear any obstructions.
• 2. Check the ice box sensor: Many De Dietrich ice makers use a small NTC or optical sensor to detect ice temperature/level. Inspect the sensor and wiring for damage or disconnection.
• 3. Test the sensor: Disconnect the sensor and measure resistance (for NTC types) or check for obvious damage (for optical sensors). Replace if faulty.
• 4. Verify wiring through the door: On models with ice in the door, flexing can break wires in the door harness. Check continuity from the ice maker connector to the main PCB.
• 5. Replace the ice maker assembly: If the motor or internal switches are defective, it is usually more practical to replace the complete ice maker module.
• 6. Restore water and power: Turn the water back on, plug in the refrigerator, and allow several hours for ice production to resume.
