Gas cooktop with electronic ignition shows F0 or similar code on a small display; burners ignite but error beeps intermittently.

Safety first: Turn off all gas burners and close the gas supply valve. Disconnect the appliance from mains power before touching ignition components.

• Step 1 – Clean burner and electrode: Remove the burner cap and head. Clean the ignition electrode and surrounding area with a soft brush and mild detergent. Ensure there is no food residue or grease.
• Step 2 – Dry thoroughly: If the cooktop was recently cleaned or a pot boiled over, moisture may be causing false detection. Dry the electrodes and burner parts completely before reassembly.
• Step 3 – Check burner cap position: Refit the burner head and cap correctly, ensuring they sit flat and centered. Misalignment can affect ignition sensing.
• Step 4 – Inspect wiring (technician): With power disconnected, lift the cooktop surface and inspect the ignition harness and flame sensing wires for damage or loose connectors on the ignition module.
• Step 5 – Replace ignition module: If electrodes and wiring are fine but F0 persists, the ignition control module may be faulty and should be replaced.

After reassembly, open the gas valve, restore power, and test each burner individually.
