How to check if ref. S1071500 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 S1071500. 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.

Symptoms and faults that the gas valve S1071500 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 or locks out due to flame failure right after starting.

  Cause: If either of the two coils of the gas valve does not receive or maintain the necessary current, the gas flow does not open in time.

  Check that power is reaching both connectors of the gas valve at the moment of ignition before replacing it.

• 02

  Gas is not reaching the burner even though the boiler is trying.

  Cause: A mechanical failure in the valve shutter prevents the gas from passing even though the coils are receiving current.

  Check that the main gas valve is fully open and that there is no air left in the line after a recent intervention.

• 03

  The display shows a gas valve fault code or warning.

  Cause: The control unit compares the signal from the coils with the expected value and indicates a fault when it detects a difference.

  Note the exact code: if it appears consistently at the same point in the ignition cycle, it is a more reliable indication than if it appears randomly.

• 04

  The boiler ignites but stops shortly after, as if it loses the flame.

  Cause: One of the two coils may fail intermittently when it heats up, shutting off the gas flow after a few seconds of operation.

  Check if the cut always takes the same time to appear: this points more to a component that heats up and fails, like this gas valve.
