Possible Causes
Liquid spill on touch panel, Shorted membrane switch, Damaged touch glass, Faulty keypad matrix on control board
How to Fix / Troubleshooting
Safety first: Disconnect the appliance from mains power.
- Clean and dry panel: If the error appeared after a spill or cleaning, gently dry the touch panel area. Allow several hours with the door open for moisture to evaporate.
- Inspect for cracks: Check the glass touch surface for cracks or impact damage that could short the keypad layers.
- Disconnect keypad: With power off, disconnect the keypad ribbon from the EOC. Restore power briefly. If F7 disappears with the keypad disconnected, the keypad is faulty and must be replaced.
- Replace keypad or control: Install a new Bauknecht touch panel assembly. If F7 persists even with a new keypad, replace the EOC.
Warning: Do not use the oven if it starts by itself or responds unpredictably; this is a safety hazard.
