How to Fix / Troubleshooting
Safety first: Disconnect the hob from mains before opening.
Diagnostic steps (technician recommended):
- Remove the hob and access the internal electronics.
- Identify the communication cable (often a multi-core low-voltage harness) between the user interface board and the power module.
- Check connectors for secure fit and signs of overheating or corrosion.
- Inspect the cable for pinched or cut insulation.
- If available, substitute a known-good cable to rule out wiring.
- If F6 persists, test by substituting either the user interface board or the power module following V-ZUG service procedures.
Repair: Replace the defective board or harness. After replacement, perform a full functional test of all zones and controls.
