Possible Causes
How to Fix / Troubleshooting
Safety first: Disconnect the oven from mains power before removing the control panel.
Panel inspection:
- Remove the front control panel assembly according to the service instructions for your Teka model.
- Inspect the touch glass and underlying PCB for signs of moisture, grease, or corrosion. Carefully clean with isopropyl alcohol and a lint-free cloth.
- Check the flat flex cable between the touch panel and the main control board for cracks, kinks, or poor insertion. Reseat the cable fully.
- If certain keys never respond, the touch panel membrane or capacitive sensor area may be defective. Replace the complete touch control panel or user interface board as specified by Teka.
- Ensure the panel is reinstalled without stress or twisting, which can affect touch sensitivity.
After repair: Restore power and test all keys and functions. If E11 persists, the main control board may have a communication fault with the interface.
