What it is

The Baxi 7211855 is a flame sensing electrode used in Baxi Ecoblue and Duo-Tec 2 boiler ranges. It sits in the combustion circuit and provides the flame signal back to the boiler's control board, allowing the PCB to confirm that ignition has taken place and to shut the gas valve if the flame is lost.

Signs this part needs replacing

  • Boiler locks out shortly after ignition, or fails to prove flame and goes to lockout
  • Repeated lockout on start-up with the burner lighting briefly then extinguishing
  • Flame signal faults or flame loss errors logged by the boiler controls
  • Visible damage to the electrode tip, insulator or lead
  • Electrode probe heavily oxidised, cracked or contaminated

Before you order

  • Confirm the boiler model and GC number against the fitment list above
  • Check the existing electrode for damage to the probe, ceramic insulator and lead
  • Inspect the burner and combustion chamber condition before refitting
  • Confirm the boiler is isolated from the gas and electrical supply before work begins
