How to check if ref. S1047000 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 S1047000. 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 PCB S1047000 resolves.

The PCB controls the ignition, modulation, and safety features of the boiler. These are the typical symptoms and what to do:

Common symptoms and faults

• 01

  The boiler tries to ignite, makes a sparking noise but the burner does not light up.

  Cause: The PCB does not send the ignition signal to the electrode at the correct time.

  Check the distance and cleanliness of the ignition electrode before replacing the PCB.

• 02

  The display indicators are all flashing at the same time or remain fixed without any apparent reason.

  Cause: A fault in the control stage of the PCB leaves the display in an undefined state.

  Perform a complete reset by disconnecting the power before assuming that the PCB is damaged.

• 03

  The boiler works well for heating but stops responding when requesting domestic hot water.

  Cause: The PCB does not correctly read the signal from the flow sensor.

  Check that the water flow is sufficient and that the flow sensor is clean before replacing the PCB.

• 04

  It turns on intermittently; sometimes it starts on the first try, and other times it requires several attempts.

  Cause: There may be a faulty contact on the PCB that causes the ignition sequence to fail randomly.

  Check that all the connectors on the PCB are properly fitted and free of oxidation before replacing it.
