Guide

How to check if the reference H022003425 is the part for your boiler

What determines it is not the boiler model, but the reference printed on the part you already have installed.

  1. Find the reference printed on the installed part and check whether it matches the catalogue reference H022003425. If it is not visible, do not identify the part from 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 and faults that the gas valve H022003425 resolves.

The gas valve regulates and modulates the gas flow to the burner. These are the typical symptoms and what to do:

Common symptoms and faults

  • 01

    The boiler does not ignite, there is no flame.

    Cause: The solenoid valve EV1 is not allowing gas to flow to the burner.

    Measure if there is power to the gas valve and check that there is a spark before replacing it.

  • 02

    The boiler is showing a lockout error related to gas.

    Cause: The valve does not open in time during ignition and the control board locks for safety.

    Note the fault code and check if it always occurs at the same moment during startup.

  • 03

    The flame flickers or goes out and reignites by itself.

    Cause: The solenoid valve does not maintain a stable gas flow during operation.

    Measure the inlet gas pressure with a manometer before considering the gas valve as the culprit.

  • 04

    I smell residual gas right after turning off the boiler.

    Cause: Wear of the internal seat of the solenoid valve EV1, which does not close completely.

    Check if the smell always appears when turning off, which indicates that the gas valve is not closing properly.

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.
