Possible Causes

Moisture or liquid on touch keys, Stuck or shorted touch sensor, Faulty touch control PCB, Loose ribbon cable between UI and main board

How to Fix / Troubleshooting

Safety first: Switch off the hob and disconnect from mains if removing from the worktop.

User checks:

  • Clean and dry the glass surface thoroughly, especially around the control area.
  • Remove any metallic objects, cloths, or covers from the control zone.
  • After at least 10 minutes, restore power and test the controls again.

Technical checks (qualified person only):

  • Access the underside and locate the touch control PCB.
  • Inspect the ribbon cable between the touch panel and the main control board; reseat connectors.
  • Check for signs of liquid damage or corrosion on the touch PCB.
  • If a specific key appears permanently activated, the capacitive sensor on the PCB may be defective.

Repair: Replace the touch control panel / user interface PCB if cleaning and reseating cables do not resolve the F5 error. Ensure the new panel is correctly calibrated according to V-ZUG procedures.
