Flame detection electrode: ignition followed by shutdown
A boiler that lights and then stops may have a flame detection issue, but the flame itself, wiring and controls also need assessment.

How the boiler confirms a flame
On appliances using ionisation detection, an electrode helps the controls verify flame presence. This is a safety function, not simply an indicator lamp. A separate ignition electrode may start the flame, depending on design.
A brief flame is an important clue
Record whether the burner lights before shutdown and the exact message displayed. Weak or unstable combustion, a detection circuit issue or another safety condition may interrupt operation. The symptom is not sufficient to decide that the electrode alone is faulty.
Diagnosis covers the complete signal path
The professional considers electrode condition and position, insulation, connections, earthing and the relevant measurements, together with burner behaviour. Manufacturer instructions determine the procedure. Do not bypass detection, alter wiring or repeatedly restart a boiler that remains in lockout.
What a complete repair involves
A compatible electrode and correct installation may be needed, but the underlying cause must also be addressed. Final checks establish reliable flame recognition and correct shutdown as appropriate. Explain any recent electrical or boiler work, since it may help the diagnosis.
