What it is

The Buderus sealing ionisation electrode is a sealing component that fits at the ionisation electrode of the appliance, supplied here in a pack of 5. It forms the seal around the electrode where it passes into the combustion chamber. The part is listed under O-rings, washers and gaskets for Buderus gas boiler spares.

Signs this part needs replacing

  • Visible flattening, hardening or cracking of the seal
  • Moisture or condensate traces around the electrode entry point
  • The electrode will not seat or seal correctly after removal and refitting
  • Repeated flame detection faults after the electrode has been disturbed

Before you order

  • Confirm the appliance model against the fit list above
  • Check the part number 7099556 matches the item being replaced
  • Establish how many electrodes are being serviced, as the pack contains 5 seals
  • Inspect the electrode body for damage before refitting
