    7. Inspect Ignition Components
      If the blue light persists, check the ignition system.

    8. Remove the boiler cover to access the ignition electrode.

    9. Clean or replace the electrode if it appears dirty or damaged.

    10. Test Electrical Connections
      A malfunctioning electrical component can also trigger the blue light.

    11. Use a multimeter to check voltage at the ignition and control board.

    12. Repair or replace any faulty wiring or components as needed.
