Saunier Duval Thematek SF 24 E Control Module Ref. S1008100
Saunier Duval Thematek presents the Módulo Mando SF 24 E, reference S1008100. This PCB controls the ignition, burner modulation, pump, and safety features of the boiler. When faults occur, the boiler may fail to start, lock out, or operate erratically, displaying errors such as F12, F18, or F13. It is compatible with models such as F 24 E, C 24 E, SC 24 E, and C 24 EO, among others. A technician must confirm through diagnosis whether it needs to be replaced when these symptoms or errors are detected.

How to check if ref. S1008100 is the part for your boiler
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.
- Find the reference printed on the installed part and check whether it matches the catalogue reference S1008100. 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 that require diagnosis on the PCB S1008100
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 display does not turn on or show anything, even though the boiler is powered.
Cause: The module controls the display, and if there is a failure in the internal power supply, the display and control are lost.
Check the internal fuse of the PCB and ensure that the power connector does not have any burnt or oxidized pins before replacing it.
- 02
The display is visible, but the buttons are unresponsive; the temperature and mode cannot be changed.
Cause: The keyboard and the screen share a microcontroller; if it fails, the key presses are not registered.
Clean the button membrane contact and check for any moisture before considering the PCB as faulty.
- 03
The boiler turns on but the display flashes, it turns off by itself or shows meaningless symbols.
Cause: An unstable power supply on the PCB causes the LCD to intermittently lose the refresh signal.
Cut the power for one minute; if the fault returns quickly, it is more likely to be the PCB and not a temporary power surge.
- 04
An error code appears that does not match any in the manual, or it changes every time it is reset.
Cause: A damaged microcontroller misinterprets the readings from the sensors and generates incorrect fault codes.
Note the exact code before resetting: if it is always different, it indicates more of a problem with the PCB than with a specific component.
Fault codes Saunier Duval that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| F12 | No signal from the user interface | Yes — it points to this display/interface module or its connection cable with the main PCB. |
| F18 | User interface fault | Yes — it corresponds to this display/control board module. |
| F13 | Main PCB fault | No — that code is for the MAIN PCB (a different part), not for this display. |
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.
