Guide

How to check if the reference 6040225 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 6040225. 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 safety valve 6040225 resolves.

The safety valve releases pressure when the circuit exceeds its setting. These are the typical symptoms and what to do:

Common symptoms and faults

  • 01

    Water is constantly dripping from the discharge tube, even when the boiler is cold.

    Cause: The valve seat does not seal properly, usually due to a trapped impurity or wear of the internal gasket.

    Before replacing it, check the air pressure of the expansion vessel with the circuit empty. If it is low, the valve will trigger more than usual without being faulty.

  • 02

    When the boiler reaches temperature, a jet of water comes out of the gas valve and then it stops.

    Cause: The pressure in the circuit rises above the set point because the system does not properly absorb the expansion of the hot water.

    Check the charge pressure of the expansion vessel and the cold filling pressure of the circuit before replacing the gas valve.

  • 03

    The valve does not release water even though the pressure gauge shows higher than usual pressure.

    Cause: The internal mechanism gets stuck due to the accumulation of limescale or because it has not been activated for a long time.

    Manually operate the bleed lever, if it has one, to check if it releases water before considering it blocked.

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.
