Multifunction PCB Saunier Duval Thematek SF 24 Ref. S10470

When you open the tap or turn on the heating, the Saunier Duval Thematek SF 24 Multifunction PCB (control board) Ref. S10470 is responsible for controlling the ignition, burner modulation, pump, and safety features of the boiler. If it fails, the boiler may not start, become locked, or operate erratically, displaying fault codes such as F11, F12, F13, or F18. This board is compatible with models from the ThemaClassic, Themafast, Thematek, Isotwin, and Isofast ranges, among others.

Guide

How to check if ref. S10470 is the part for your boiler

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

  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 that require diagnosis on the PCB S10470

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 does not turn on when the switch is pressed.

    Cause: If the PCB does not receive power, there is no energy for the boiler to operate.

    Check if the plug and the main switch of the boiler work with another device before inspecting the PCB.

  • 02

    It turns on and after a few seconds shows a different fault code each time.

    Cause: A fault in the PCB causes inaccurate readings that vary with each attempt.

    Note the fault codes from three or four consecutive attempts; if they are different, it is more likely that the issue is with the PCB rather than a sensor.

  • 03

    The remote control or the panel do not respond to the buttons.

    Cause: The panel needs the PCB to process the microprocessor pulses.

    Try resetting the remote and check the batteries; if the panel still does not respond, the problem is with the PCB.

  • 04

    The boiler starts up correctly but shuts down without warning, without displaying a fault code.

    Cause: A fault in the PCB can interrupt the supply to the components without generating a fault code.

    Check if the shutdown always occurs at the same moment in the ignition cycle; if so, point to the PCB before considering an external component.

Fault codes Saunier Duval that require diagnosis

CodeFaultTechnical checks
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.
