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 control panel display does not turn on, it remains dark.
Cause: The display module is not receiving power from the main PCB, either due to the connector or a fault in the module itself.
Check that the connector joining this module to the main PCB is properly seated and that there are no oxidized or bent pins.
- 02
The display does not show any digits or icons even though the boiler is functioning.
Cause: The microcontroller of this display module stops refreshing the screen, without affecting the rest of the electronics.
Check if the boiler is still heating normally; if so, the fault is in the display, not in the power PCB.
- 03
The control panel does not respond to the presses.
Cause: This module integrates the control panel, so its failure also affects the response of the buttons.
Try resetting the boiler by cutting the main power for 30 seconds before declaring the panel faulty.
- 04
The screen flickers or turns off and on intermittently.
Cause: A poor connection in the display module connector causes intermittent power cuts.
Disconnect and reconnect the connector of the module; if the blinking changes when moving the cable, the problem is with the connection.
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.
