Guide

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.
Diagnosis and fault codes

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 is completely dead, no lights or display, it shows no signs of life.

    Cause: It is possible that the power supply section of the PCB has failed and is not supplying current to the rest of the circuit.

    Check the internal fuse of the PCB and the input current before declaring it faulty.

  • 02

    The fault code does not clear even after resetting the boiler several times.

    Cause: The PCB may have damage to the part that manages the memory or the microprocessor.

    Note the code, cut the power for a full minute, and reset before changing the PCB.

  • 03

    The pump and the fan start, but the boiler does not ignite the burner.

    Cause: It is possible that the output from the PCB that activates the gas valve or the ignition electrode has failed.

    Check with a multimeter if there is power reaching the gas valve when the PCB should activate it.

  • 04

    The remote control loses connection and does not recognize the boiler.

    Cause: The communication module integrated into the PCB may have stopped sending a signal.

    Re-pair the remote control following the manufacturer's procedure before replacing the PCB.

Fault codes from Saunier Duval that this spare part resolves.

CodeFaultDiagnosis and solution
F13Main PCB faultYes — it is the direct code of the PCB. Check 230 V, fuse, connectors, and grounding; if it persists, replace the PCB.
F11No signal is reaching the main circuitPossible — first rule out wiring and connectors to the PCB; if they are fine, it is usually the PCB.
F12No signal from the user interfaceNormally not — it's usually the display or its cable, not this main PCB.
F18User interface faultNormally not — it corresponds to the panel/display, not to this PCB.

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.
