Safety first: Unplug the air fryer before removing the control panel or top cover.

Steps to address keypad communication faults:

1. Clean the exterior: Wipe the control panel with a slightly damp cloth to remove grease or residue. Do not spray cleaner directly onto the panel.
2. Power reset: Unplug for 5 minutes, then reconnect and test. If E6 persists, continue.
3. Access the control panel: Remove screws securing the top or front fascia. Carefully lift the panel to expose the touch panel ribbon cable and main control PCB.
4. Reseat connectors: Gently disconnect the ribbon cable, inspect for corrosion or bent contacts, then reconnect firmly. Ensure the cable is not pinched when reassembling.
5. Inspect for damage: Look for cracks in the touch panel, moisture intrusion, or burnt spots on the user interface PCB. If damaged, replace the touch control panel assembly.
6. Replace main control PCB if needed: If a known-good panel still triggers E6, the main control PCB may have a failed interface circuit and should be replaced.

Avoid using sharp objects or excessive force on the touch panel to prevent future damage.
