Guide

How to check if ref. 65100244 is the part for your boiler

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

Find the reference printed on the installed part and check whether it matches the catalogue reference 65100244. If it is not visible, do not identify the part from its shape alone.
Check the full boiler model on its data plate and look for it in the model associations on this page.
Compare the connections and physical body with the original part before installation.
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 gas valve 65100244

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 tries to ignite, you can hear the spark igniter, but the flame does not catch.
Cause: The gas valve does not allow gas to flow to the burner at the moment of ignition, and the control board does not detect a flame.
Confirm that the main gas valve is open and that other gas appliances in the house are working before checking the gas valve.
02
The boiler turns on and off by itself after a few minutes, and then tries again.
Cause: The gas supply is interrupted or fluctuates during operation, and the boiler protects itself by shutting down the burner.
Note if the cut always coincides with the same demand, domestic hot water or heating, to narrow down whether it is the gas valve or another component of the gas circuit.
03
The flame rises and falls without you having touched anything, or it sounds different at times.
Cause: The valve does not modulate the output pressure to the burner properly, and the gas flow varies irregularly.
Check that the incoming gas filter is not dirty, as a clogged filter can cause the same symptom of irregular modulation.
04
The boiler gets locked due to an ignition fault and needs to be reset manually.
Cause: Without sufficient gas in the burner, the flame detector does not confirm ignition within the safety time.
Before changing the gas valve, check the ignition or ionization electrode and its wiring, as they can cause the same fault.

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.
