Safety first: Disconnect the oven from mains power before removing the control panel.

Power reset: Leave the oven powered off for 10–15 minutes to allow capacitors to discharge, then restore power. If F6 clears temporarily but returns, suspect an intermittent connection.
Inspect control panel: Remove the front control panel (usually by removing screws along the top or sides). Carefully pull it forward to access the ribbon cables.
Reseat connectors: Disconnect and reconnect the flat ribbon cable(s) between the user interface (UI) and the main control board. Ensure they are fully inserted and locked.
Check for moisture/grease: Look for signs of condensation or grease on the back of the touch panel. Gently clean with a dry, lint-free cloth. Do not use liquid cleaners on the electronics.
Component replacement: If the error persists, either the UI board or the main control board is likely faulty. Replacement typically requires ordering the exact AEG part number from the rating plate/model documentation.

Warning: Static discharge can damage electronic boards. Ground yourself before touching PCB contacts.

Oven display shows F6, oven does not start or shuts down unexpectedly, sometimes accompanied by beeping.
