Guide

How to check if it is the part for your boiler

The part reference, model, and equipment revision must be verified against the manufacturer's documentation.

  1. Find the reference printed on the installed part and check whether it matches the catalogue reference —. If it is not visible, do not identify the part by its shape alone.
  2. Check the full boiler model on its data plate and look for it in the model associations on this page.
  3. Compare the connections and physical body with the original part before installation.
  4. If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Diagnosis and fault codes

Symptoms that require diagnosis in the burner

The burner performs the combustion of gas. These are the typical symptoms and what to do:

Common symptoms and faults

  • 01

    The boiler tries to ignite but does not generate a spark and locks out after a few seconds.

    Cause: The spark train does not produce the necessary arc to ignite the pilot flame or the main burner.

    Look through the peephole to see if there is a spark at the electrode when starting; if there is nothing, first check the high voltage cable and its connection.

  • 02

    A strange clicking or buzzing sound is heard in the burner just before the boiler locks out.

    Cause: The ignition component fails intermittently and generates an irregular arc instead of a clean spark.

    Check that the electrode is clean and has the correct gap, and that it is not touching the ground, before declaring the part defective.

  • 03

    The boiler locks out in cold due to ignition failure and needs to be reset every time.

    Cause: Without a reliable spark, the control board does not detect flame within the safety time and cuts off the gas supply.

    Also check the gas supply and the condition of the gas valve before replacing the spark electrode assembly: the symptom is similar in both cases.

  • 04

    Sometimes it ignites on the first try and other times it gets blocked, without a clear pattern.

    Cause: The spark train fault is intermittent, typical of moisture, dirt, or internal degradation of the component.

    Repeat the cold start three or four times in a row and note if the fault occurs consistently or only sometimes.

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.
