Ignition electrode: a boiler that will not light

An ignition electrode helps start the flame. Failed ignition may also involve the supply, wiring, gas valve, controls or combustion conditions.

Ignition electrode: a boiler that will not light

Ignition and flame detection have different roles

The ignition electrode creates the spark in an appliance using this design. Flame detection confirms that combustion is established; some designs combine functions, others use separate components. The exact arrangement must be checked against the boiler model.

Describe the startup sequence

Tell the technician whether you hear repeated attempts, whether a flame appears briefly and which message follows. A clicking sound does not prove that a suitable spark is reaching the right location. Conversely, an ignition fault does not by itself prove electrode failure.

What the professional assesses

Checks may include the electrode condition, insulation, mounting, cable and the specified position, alongside gas supply and the control sequence. Deposits or a cracked insulator can matter. Do not bend the electrode or set an arbitrary gap: manufacturer dimensions and procedures apply.

Repair and verification

A suitable part must match the appliance, and disturbed seals or combustion components require appropriate checks. Repeated manual resets are not a repair. After the intervention, the professional verifies reliable starting and the relevant safety and combustion conditions.

Arrange a diagnosis in Anderlecht

Provide the make, exact model, full fault message and when the symptom occurs. Keep the appliance accessible without opening it, and mention previous repairs or leaks. ChauffePro can discuss breakdown diagnosis, repair and servicing. Availability and the proposed work are confirmed for your installation.
