Common symptoms and faults
- 01
The boiler tries to ignite, you can hear the spark, but no flame is produced.
Cause: If the nozzles of this manifold are blocked, not enough gas reaches the electrode for the flame to ignite.
Check the shut-off valve and the gas inlet pressure before declaring the nozzles as obstructed.
- 02
The flame ignites for a moment and then goes out by itself after a few seconds, and the boiler locks out.
Cause: A fault in the wiring of the electrode or the thermocouple of this ramp causes the boiler to think there is no flame and cut off the gas for safety.
Check that the thermocouple or ionization electrode cable is properly connected and without breaks before replacing the entire burner.
- 03
The flame burns with an irregular color among the different nozzles of the manifold.
Cause: The worn or dirty nozzles of this model distribute gas poorly among the different ignition points.
Visually inspect the nozzles for dirt, rust, or deformation before replacing the entire part.
These symptoms can have more than one cause. If your boiler displays a fault code, send it to us via WhatsApp along with a photo of the labeling, and we'll tell you if this is the part.
