Why does my Rapido Boiler ignition automat report a fault shortly after the burner activates?
- KKevin SmithAug 2, 2025
A fault report from the ignition automat shortly after the burner activates in your Rapido Boiler may be due to absent or insufficient ionization current (required minimum value 5 µA), a dirty or faulty ionization electrode, absent ignition, a faulty ignition transformer, or a faulty ignition automat. You should measure the ionization current. Check the cable connection in the ignition automat and to the electrode. Check whether the gas outlet of the burner lance under the ionization electrode is not clogged, and clean if necessary. Clean or replace the ionization electrode. Replace the ignition transformer. Replace the ignition automat.
