Why is my Ferroli OPTIMAX HE 31 S not igniting?
- D
  Danielle PhillipsAug 16, 2025
  If your Ferroli Boiler isn't igniting, it could be due to several reasons: a lack of gas supply (in which case, check the gas flow and ensure the pipes are purged of air), a fault with the detection or ignition electrode (ensure they're correctly positioned and clean), a defective gas valve (check and replace if necessary), incorrect inlet gas pressure (verify the pressure), or a blocked siphon (inspect and replace if needed).

  If your Ferroli boiler fails to establish a flame after the ignition phase, the issue could stem from a faulty detection electrode (check its position and replace if necessary), an unstable flame (inspect the burner), an incorrect gas valve offset (verify the offset at minimum power), a blocked flue gas circuit (ensure it's clear), or a blocked siphon (inspect and replace if needed).
