Saunier Duval PCB - Various Models Ref. S1047000
Saunier Duval PCB - various models Ref. S1047000, is a component that controls the ignition, burner modulation, pump, and safety features of the boiler. If it fails, the boiler may not start, become locked, or operate erratically. Users may notice symptoms such as fault code F13, which indicates a failure of the main printed circuit, or F11, which signals that there is no signal reaching the main circuit. This PCB is compatible with models from the ThemaClassic, Themafast, Thematek, Isotwin, Isofast, and Thema ranges, among others. It should be replaced when it shows operational faults or errors in the system.

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.
- 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.
- 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 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 shows no signs of life: no lights, no display, not the slightest noise when turned on.
Cause: The PCB is not receiving power to supply the circuit.
Measure if 230V is reaching the boiler and check that the main fuse (if accessible) is not blown before considering that the PCB is faulty.
- 02
The display shows a fixed fault code and does not start even if you reset it several times.
Cause: The PCB has detected a safety fault and is blocking the ignition to protect the boiler.
Note the exact code and consult the manual: many lockouts may be due to a dirty sensor or air in the circuit, not necessarily the PCB.
- 03
The thermostat or remote control is unable to communicate with the boiler, or it disconnects constantly.
Cause: The PCB manages communication with the peripherals, and if it fails, the link is lost.
Change the batteries in the remote and check that the communication wiring is not loose or corroded before assuming that the PCB is faulty.
- 04
The boiler turns on, runs for a while, and then shuts off on its own without any apparent reason, repeatedly.
Cause: A relay on the PCB loses contact when switching the pump or the burner and cuts off the supply.
Check if the cut coincides with a click on the PCB; gently tapping the casing (with the boiler off) may help identify a loose relay or solder joint.
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.
