What it is

The Sime 6174810 is a gasket for the ionisation electrode on Sime gas boilers. It seals the electrode where it passes into the combustion chamber, maintaining a gas-tight joint at the mounting point. It is used across the Sime Dewy and Planet Dewy appliance families.

Signs this part needs replacing

  • The gasket is cracked, hardened or perished
  • Soot staining or signs of leakage around the electrode mounting
  • Boiler locks out or fails to prove flame because of a poor ionisation signal
  • The gasket is damaged or deformed when the electrode is removed for servicing

Before you order

  • Confirm your appliance model and GC number against the fitment list above
  • Check the existing electrode and gasket part numbers before ordering
  • Consider whether the ionisation electrode itself also needs replacing
