Cointra Supreme 11 E TS PCB Ref. 39843580
The control PCB governs the ignition, burner modulation, pump, and safety features of the Cointra Supreme 11 E TS boiler. When it fails, the boiler may not start, become locked, or behave erratically, potentially displaying fault codes F37 or F42. This PCB is compatible with the models Supreme 11 E TS, Supreme 14 E TS, and Supreme 17 E TS, among other boilers in the Cointra Supreme E TS range. It is replaced when these symptoms or operational faults occur.

How to check if the part number 39843580 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 39843580. 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 39843580 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 boiler is unresponsive, neither the display nor any indicator lights turn on.
Cause: The PCB is not receiving or distributing power to the other components.
Check that power is reaching the boiler and inspect the fuse on the PCB before declaring it dead.
- 02
When pressing the ignition button, the spark does not ignite and the boiler does not start.
Cause: The transformer or ignition relay integrated into the PCB does not generate the ignition signal.
Check that the ignition electrode is clean and properly connected before attributing the fault to the PCB.
- 03
The screen turns on but gets stuck and does not respond to any button.
Cause: The electronic control hangs due to an internal fault of the microprocessor.
Cut the power for a few minutes to perform a complete reset and check if the lockout occurs again.
- 04
The boiler works for a while and then shuts down by itself displaying a fault code.
Cause: The PCB detects an out-of-range condition and cuts off the gas supply for safety.
Note the exact code displayed on the screen and check the component indicated before replacing the entire PCB.
Fault codes for Cointra that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F37 | Disconnected or faulty pressure switch. | If the boiler is not working and shows this code, it may be that the water pressure switch is disconnected or damaged. Check the condition of the pressure switch to determine if the fault lies with the PCB. |
| F42 | Heating sensor anomaly. | If the boiler is experiencing heating issues and shows this code, it may be that the heating sensor is failing. Check the sensor and its condition to determine if the fault lies with the 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.
