Ferroli Domina F 24 E PCB Ref. I39807690
The Ferroli Domina F 24 E PCB is the component responsible for controlling the ignition, burner modulation, pump, and safety features of the boiler. When it malfunctions, the boiler may fail to start, become locked, or operate erratically. Users may notice fault codes such as F36, F25, A02, F04, or A23. This PCB is compatible with several models, including Domina F24 E, Domina C24 E, Domicompat F24, Combi F24, and Optimax 25C, among others. A technician must confirm through diagnosis whether it needs to be replaced when operational issues are detected in the boiler.

How to check if the reference I39807690 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 I39807690. 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 I39807690
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 completely dead: no pilot light, no display, nothing at all.
Cause: The PCB is not supplying voltage to the other components because its power supply stage has failed.
Check that 220V is arriving at the main input and rule out the fuse on the control board before buying another one.
- 02
The remote control or the control panel does not respond to any button press.
Cause: The PCB is not managing the signals from the panel even though it has power.
Disconnect and reconnect the control panel connector on the PCB, sometimes the fault is a loose connection, not the board.
- 03
The boiler makes ignition attempts, stops, and tries again and again.
Cause: The PCB does not complete the startup cycle because it does not receive or does not interpret a safety signal correctly.
Check that the sensors and pressure switch are properly connected to the PCB before declaring it faulty.
- 04
It has stopped heating overnight without any prior warning.
Cause: A component of the PCB has suddenly failed and interrupts the ignition sequence.
Note if there is any LED flashing at the time of the fault, this will help narrow down whether it is the PCB or another component.
Ferroli fault codes that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| F36 | Main PCB fault | The boiler indicates a direct fault of the main board (CVBC). Check for moisture/damage on the board, absent control outputs, and correct power supply; if it persists, replace the PCB. |
| F25 | Software fault | Software fault in the PCB; after cutting and restoring power, if the error persists, the documented solution is to check/reprogram or replace the CVBC. Check for abnormal resets and input voltages before replacing. |
| A02 | Flame signal present with burner off | The PCB may interpret an erroneous ionization signal (analog input 'stuck' or ignition stage fault). Check electrode/wiring and ionization reading; if they are correct and A02 persists, the cause is the PCB. |
| F04 | Wrong card parameter setting | Incorrectly configured control board parameters (e.g., new PCB without parameterization). Check/load the manufacturer's parameters; if they cannot be saved or become corrupted, replace the PCB. |
| A23 | Card parameter error | Internal parameters error of the PCB. Check/adjust parameter settings according to the service manual; if the error reappears, the PCB is the cause. |
| A24 | Card parameter error | Another error with the control board parameters. Check and reprogram parameters; if it doesn't correct or doesn't accept recording, replace 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.
