Possible Causes
How to Fix / Troubleshooting
Safety first: Turn off the gas supply at the isolation valve and disconnect electrical power before removing any panels.
User checks:
- Confirm that the hob is plugged in (if applicable) and that the circuit breaker has not tripped.
- Listen for clicking when a control knob is turned to ignite; if there is no clicking on any burner, the ignition system is not powered.
Technician checks:
- Verify 230 V AC supply at the hob terminal block.
- Inspect the ignition transformer / spark generator unit for signs of overheating or cracking.
- Check the low‑voltage harness from the ignition module to each spark electrode for secure connections.
- Test the ignition switch contacts in the burner control knobs for continuity when pressed or turned to the ignition position.
Remedy: Replace the faulty spark generator / ignition module or defective ignition switches as required. After reassembly, perform a gas leak test on all disturbed joints.
