What it is

The Hamworthy 573409091 is an ionisation rod — a flame sensing electrode used in gas boilers. It sits in the combustion path and provides the flame signal that the boiler control uses to prove ignition and supervise the burner. It is listed in the electrodes category of gas boiler spares.

Before you order

  • Confirm the number on the existing electrode or in the appliance documentation matches 573409091 before ordering.
  • Inspect the electrode, its insulator and its lead for contamination, cracking or damage, as these affect the flame signal.
  • Check the current state of the burner and combustion readings so the electrode is not replaced for a fault caused elsewhere.
