Saunier Duval ThemaClassic PCB Ref. S10470
The Saunier Duval ThemaClassic boilers use the Saunier Duval ThemaClassic PCB Ref. S10470, with manufacturer reference 0310144400L12. This control board is responsible for managing 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 F13, F11, F12, or F18. It is compatible with several models, including the F 25 E, F 24 E, and C 24 E. It should be replaced when these symptoms or fault codes are detected.

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.
- 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.
- Check the full boiler model on its data plate and look for it in the model associations on this page.
- Compare the connections and physical body with the original part before installation.
- If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
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 does not turn on, neither the display nor any indicator lights, as if it is not receiving power.
Cause: The power supply stage of the PCB may have failed and is not distributing voltage to the rest of the components.
Check the fuse on the PCB, the thermal switch of the installation, and verify that power is reaching the boiler.
- 02
The display shows a different fault code each time, or the same warning appears and disappears on its own.
Cause: The microprocessor on the PCB misinterprets the sensor signals or intermittently loses the reading.
Note the exact code and check that the connectors of the sensors are properly fitted before replacing the PCB.
- 03
You can hear the relays on the PCB clicking, but neither the pump nor the fan starts.
Cause: The output relays on the PCB may be stuck or burnt and are not closing the circuit to those components.
Measure with a multimeter if there is output current to the pump or fan connector when the PCB gives the command.
- 04
The home's control or thermostat is unable to communicate with the boiler and appears as disconnected.
Cause: The communication bus that manages the PCB may have stopped responding.
Check or replace the bus cable and reset the remote control before declaring the PCB faulty.
Fault codes from Saunier Duval that this spare part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F13 | Main PCB fault | Yes — it is the direct code of the PCB. Check 230 V, fuse, connectors, and grounding; if it persists, replace the PCB. |
| F11 | No signal is reaching the main circuit | Possible — first rule out wiring and connectors to the PCB; if they are fine, it is usually the PCB. |
| F12 | No signal from the user interface | Normally not — it's usually the display or its cable, not this main PCB. |
| F18 | User interface fault | Normally 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.

Data read on the part and in the manufacturer's documentation
What we have not been able to verify does not appear here.
- voltage
- 24VAC
- power
- 6A
- The title of the current catalog combines two references (S1047000 and 1008200); there is only one source supporting that relationship, not the two independent ones required to confirm it, so it is not included as a definitive fact.
