How to check if ref. S1009000 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 S1009000. 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 S1009000 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 won't turn on, there are no lights or display, as if it isn't receiving power.
Cause: The PCB is the control center: if an internal component fails, it stops receiving power and does not operate.
Check the fuse on the PCB and the power supply before declaring it faulty.
- 02
The display shows a fault code that is not fixed; it appears and disappears without a pattern.
Cause: The relays and traces on the PCB degrade over time and cause intermittent reading faults.
Note the exact code and repeat the ignition cycle two or three times to see if the fault is constant or sporadic.
- 03
The boiler ignites but does not respond to the thermostat or the control, as if it is not receiving commands.
Cause: The PCB manages the demand signals; if the input circuit fails, it ignores external requests.
Check the wiring and connection of the thermostat or control before replacing the PCB, a loose connection can cause the same symptom.
- 04
It turns off by itself halfway through a heating or domestic hot water cycle, without warning.
Cause: A fault in the PCB can trigger a false safety mechanism and cut off the supply without a real reason.
First, rule out the temperature sensors and the pressure switch, as they can also cause shutdowns and are cheaper to check.
Fault codes from Saunier Duval that this spare part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 12 | User interface or remote control faulty. | The display/interface module S1009000 fails (e.g., moisture or damaged electronics) and the boiler detects an interface fault; communication with the main PCB may also be affected. Check connections between the main PCB and the interface board, dry if there is moisture, and if the issue persists, replace the display. |
| 18 | User interface fault. | Inherent defect of the display board S1009000 (interface), identified by the electronics as an interface fault. Check wiring/connections and, if not resolved, replace the display module. |
| 20 | User interface not compatible with the boiler. | A display/interface S1009000 has been installed with a revision/code not compatible with the unit or has not been reconfigured after the change, causing the boiler to detect incompatibility. Check 'interface revision code'/'boiler code' in the data menu and install the correct version or reconfigure. |
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.
