How to Fix / Troubleshooting
Safety first: Disconnect from mains immediately. Internal high-voltage components can retain charge; only qualified personnel should open the hob.

- Visual inspection (technician): Remove hob from worktop and inspect the underside for burnt smells, discoloured components, or damaged wiring on the affected coil.
- Test coil continuity (technician): Use a multimeter to check the resistance of the induction coil. An open circuit indicates a failed coil.
