Display shows E14; unit indicates door or bin not closed even when it is shut.

Safety first: Unplug the unit before accessing switch wiring.

Steps:

• 1. Locate door/bin switch: Identify the switch on the cabinet frame or inside the bin area. It may be a small plastic plunger or a hidden magnetic reed switch.
• 2. Check alignment: Ensure the door or bin front aligns properly with the switch or magnet. Adjust hinges or mounting screws if the door is sagging.
• 3. Test switch: Use a multimeter to check continuity while opening and closing the door. Replace the switch if it does not change state.
• 4. Inspect magnet: For magnetic systems, verify the magnet is still present in the door trim and has not fallen out.
• 5. Replace faulty parts: Install a new door switch or magnet as required, ensuring secure mounting and correct wiring.
