Guide

How to check if ref. S10470 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 S10470. 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 S10470 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 off, with no indicator lights on, and it does not respond to anything.

    Cause: This PCB is the control center of the entire boiler: if it loses power or malfunctions, the unit will not start at all.

    Check the fuse on the control board itself, if accessible, and the input voltage before replacing it.

  • 02

    It smells burnt or there is a dark mark next to some component of the PCB.

    Cause: A voltage spike or a short circuit can damage traces or components of the control electronics.

    With the boiler unplugged, visually inspect the PCB for burns before assuming a replacement is necessary.

  • 03

    The boiler works for several days without any issues and then suddenly gets locked, with no clear pattern.

    Cause: An intermittent fault in the control board, such as a solder joint or a capacitor, causes sporadic faults that are difficult to reproduce on demand.

    Keep a record of when the blockage occurs, the time, and whether it coincides with domestic hot water or heating, to see if there is a pattern.

  • 04

    The remote control or the control panel stops communicating with the boiler.

    Cause: The PCB is the one that manages communication with the control; if that module fails, the control is left without data.

    Check that the remote control has the correct power supply and that the communication cable or bus is properly connected 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.
