E3 appears on the display; ice basket may not move or the harvesting cycle fails, with ice remaining stuck on the evaporator.

Safety first: Disconnect the appliance from power before inspecting moving parts.

• 1. Empty the ice basket: Remove all ice from the storage bin and ensure the basket is correctly seated.
• 2. Check the ice full sensor: On many H.Koenig ice makers, the ice full sensor is an infrared pair (emitter and receiver) on opposite sides of the bin, or a mechanical lever above the basket. Clean the sensor windows with a soft cloth to remove condensation or scale.
• 3. Inspect for obstructions: Make sure no ice cubes or plastic parts are blocking the sensor or lever. Verify the ice shovel/arm can move freely during harvest.
• 4. Reseat connectors: Remove the cover and trace the sensor wiring to the control board. Reseat the connector and check for damaged wires.
• 5. Test operation: Plug the unit back in and start a cycle while observing the sensor area. If E3 reappears and the sensor is clean and aligned, the sensor assembly may need replacement.

Warning: Keep fingers clear of the ice shovel and moving arms when the unit is powered.
