What it is

The Buderus 7100238 is an ionisation electrode for Buderus gas boilers. It sits in the burner circuit and provides the flame sensing signal that the control board uses to confirm the burner has lit and to shut the gas valve if the flame is lost.

Signs this part needs replacing

  • Boiler locks out shortly after the burner lights because the flame signal is not detected
  • Repeated flame failure lockouts with the burner igniting and then shutting down
  • Intermittent or unstable flame sensing causing nuisance lockouts
  • Boiler fails to run for a full heating cycle despite ignition occurring
  • Visible damage, contamination or degradation of the electrode probe or its lead

Before you order

  • Confirm the boiler model against the data plate and cross-check it against the fit list above
  • Check the part number on the existing electrode matches 7100238 where it is legible
  • Inspect the electrode lead and plug connector for damage, as a poor connection can mimic electrode failure
  • Confirm the appliance is being worked on by a competent, gas-safe registered engineer
