Saunier Duval Themafast F 24 E Display Module Ref. S1017200
The Saunier Duval Themafast F 24 E Display Module is a control PCB that manages 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. Users may notice fault codes such as F11, F12, F13, or F18. This module is compatible with boilers from the Themafast range, including the Themafast C 24 E model, among others. It should be replaced when the mentioned symptoms or associated fault codes are detected.

How to check if the part S1017200 is the one 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 S1017200. 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 S1017200 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 screen does not display anything, not even when turning on the boiler.
Cause: This module generates the visible image on the control panel; if it fails, there is no indication even though the boiler operates internally.
Check that the boiler is actually on and heating (pump noise, hot water) to rule out that the fault is with the main PCB and not with the display.
- 02
The screen is visible, but incomplete: segments, lines, or parts of the icons are missing.
Cause: A fault in the display module or its connection to the main PCB leaves parts of the display unrefreshed.
Check the flat cable or connector that connects the display module to the main PCB before replacing the module.
- 03
The + and - buttons do not change the temperature or any adjustable value.
Cause: These keys are part of the display module; if the internal contact wears out, the press is not transmitted.
Try pressing with different pressure or several times in a row: if it sometimes responds, it is a contact issue with the button, not with the boiler.
- 04
The manual/reset button does nothing when pressed, not even with the boiler in fault.
Cause: The reset is executed through this module; if the contact of that key fails, the command never reaches the main PCB.
Try resetting by cutting off and restoring the main power to the boiler: if it resets this way, the fault is in the button, not in the PCB.
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.
