Saunier Duval Opalia LCD Display Module Ref. S1208600
The control PCB of the Saunier Duval Opalia LCD display module manages the ignition, burner modulation, pump, and safety features of the boiler. If it fails, the boiler may not start, become locked, or exhibit erratic behavior. This issue may manifest with fault codes such as F11, F12, F18, or F20. It is compatible with the Opalia F (supercomfort) and Opalia C boilers, including models such as Opalia F 11 E, Opalia F 14 E, and Opalia C 16 E, among others. It is recommended to replace it upon noticing symptoms of failure in its operation.

How to check if the part S1208600 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 S1208600. 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 S1208600 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 LCD screen does not turn on, it is completely blank.
Cause: The display module is not receiving power or the LCD screen is damaged.
Check that the boiler has power and that no fuse has blown before replacing the display.
- 02
The flow rate in L/min and the temperature in °C are not visible, although the rest of the display is functioning.
Cause: The flow and temperature indicators depend on this module; if its circuit fails, they will not be displayed even if the boiler is operating.
Check if the water comes out hot from the tap: if the boiler is working but the display does not show any information, the fault is in the display.
- 03
The flame, fan, or bulb icon does not light up when it should.
Cause: Each icon receives a signal from the control unit and is displayed on the screen; a damaged segment of the LCD can leave that icon off.
Check if the fan is running or if the flame is visible through the sight glass even if the icon does not light up: if it works but is not displayed, the issue is with the screen.
- 04
The screen shows flashing, blurry, or half-visible symbols.
Cause: This usually occurs due to a loose connector between the LCD module and the control board.
Check the wiring and the connector of the display before replacing the complete module.
Fault codes from Saunier Duval that this spare part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F11 | Communication error main/interface boards | The display/interface module (S1208600) may fail or not power correctly, preventing the main PCB from receiving/establishing communication; check 5 V/3.3 V on the HMI and continuity/status of the harness and connectors, or test with a known good S1208600. |
| F12 | Communication error between interface/main boards | The S1208600 interface may not respond (electronic or communication fault), causing frame loss to the PCB; check voltages, data/ground lines, and HMI→PCB wiring, or rule out by temporarily replacing the display with another operational one. |
| F18 | User interface fault | Direct fault of the S1208600 display/interface module (HMI), typically due to electronic failure or lack of power supply; check power supply at the connector, perform visual inspection, and replace the module for confirmation. |
| F20 | User interface incompatible with main board | An incompatible interface/display (different reference/version) has been installed with the main PCB; check that the HMI reference is S1208600 and valid for the model, and replace it with the compatible version. |
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.
