Immergas Caesar Eco 11 Display PCB
When you open the hot water tap, the PCB of the Immergas Caesar Eco 11, reference S1047000, is responsible for controlling the ignition and modulation of the burner. If this part fails, you will notice that the boiler does not start, gets locked, or exhibits erratic operation, potentially showing faults such as AL62, AL80, or AL98. It is compatible with boilers from the Caesar range, including models like Eco 11, Eco 14, and Eco Extra 11-14, among others. It is recommended to replace the board when you experience these symptoms or faults to restore the boiler's operation.

How to check if ref. 042650 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 042650. 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 042650 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 screen does not turn on, it remains completely black.
Cause: If the display board fails, it does not light up even though the boiler continues to operate correctly.
Check if the boiler heats water or produces domestic hot water even if you don't see anything on the screen; if it works blindly, the problem is with this control board.
- 02
The display does not show any temperature, icons, or fault codes.
Cause: The LCD circuit of this PCB has stopped displaying an image, although it is still receiving power.
Check if any pilot light or LED on the control panel is still active; if there is power but no image, the fault is usually in the LCD of this PCB.
- 03
The screen flickers, it appears intermittently or turns off and on by itself.
Cause: A poor connection in the connector that links this PCB with the main one causes intermittent image cuts.
Before replacing it, disconnect and reconnect the connector that goes to the main PCB; often the fault is due to a contact issue, not the board itself.
Fault codes from Immergas that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| AL62 | Request for full calibration (calibrate the gas valve). | After replacing or reprogramming the control/display board, the boiler detects the absence of board setting and requires gas valve calibration; verify this by entering the service menu and confirming AL62, then perform the calibration as indicated by the manual. |
| AL80 | Lockout due to gas valve driver issue (malfunction of the PCB controlling it). | The driver circuit that controls the valve is on the control/display board; if the PCB fails, it does not send a signal to the valve and the boiler locks with AL80; check by measuring the output to the valve and, if the valve is OK, confirm a defect in the board. |
| AL98 | Lockout due to reaching the maximum number of software errors. | The software/configuration resides on the board; accumulation of errors or parameter corruption in the PCB causes AL98; check by attempting a reset and, if it reappears, check/reprogram or replace the board. |
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.
