What it is

The Buderus Sealing Ion. Electrode (10 PC) is a sealing ionisation electrode supplied in a pack of 10. It is fitted to Buderus 600 series gas boilers, where the ionisation electrode monitors flame presence and signals the control board to maintain safe burner operation. The sealing design allows the electrode to sit in the burner assembly without leakage at the mounting point.

Signs this part needs replacing

  • Boiler locks out shortly after ignition or fails to prove flame
  • Repeated flame failure faults logged on the control board
  • No flame signal detected during a combustion check
  • Cracked, discoloured or eroded electrode tip or damaged insulation
  • Visible damage or deterioration at the sealing face or lead connection

Before you order

  • Confirm the appliance model matches one of the listed Buderus 600 series boilers
  • Check the existing electrode part number against 73586S
  • Inspect the electrode lead and plug for damage before fitting
  • Confirm the quantity required, as this item is supplied as a pack of 10
