Ferroli Domitop F 24 E PCB Ref. 39809261
The control PCB Ferroli Domitop F 24 E Ref. 39809261 manages the ignition, burner modulation, pump, and safety features of the boiler. When it fails, the boiler may not start, lock out, or behave erratically, showing faults such as A02, F04, A23, or A24. This part is compatible with several models, including the Domitop F 24 E, F 30 E, C 24 E, and C 30 E, among others. It should be replaced when these symptoms or faults occur, as it directly affects the operation of the boiler.

How to check if ref. 39809261 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 39809261. 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 39809261 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 completely off: neither the display nor any LED lights up.
Cause: The correct power supply is not reaching the PCB, so no circuit of the boiler is receiving current.
Check the fuse on the PCB and confirm with a multimeter that the 230V current is reaching the terminal block.
- 02
The boiler turns on and off by itself without anyone touching the thermostat.
Cause: A fault in the control microprocessor sends on and off commands that do not correspond to the actual demand.
Note the times it occurs and if it coincides with the use of another nearby appliance; an external electrical interference can simulate this same fault.
- 03
The fan starts but the circulation pump never turns on.
Cause: The relay on the PCB that controls the pump is not closing the contact.
Bypass or power the pump directly to check that it spins properly before blaming the PCB.
- 04
The boiler does not recognize any command from the remote control or the buttons on the panel itself.
Cause: The PCB has lost internal communication between the microprocessor and the user interface.
Try resetting with the boiler's own button and check the flat connector that connects the PCB with the control panel.
Fault codes for Ferroli that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| A02 | Electrode or PCB fault. | The PCB may cause flame detection with the burner off or not correctly manage the electrode signal; first check the electrode/wiring, and if they are correct, check the ionisation circuit and PCB outputs. |
| F04 | Parameter fault on the control board: incorrect setting on the PCB. | Internal parameters of the PCB incorrectly loaded/configured (e.g., after replacement or power cut); verify/reload service values and, if not possible, replace the PCB. |
| A23 | PCB parameter error. | Incorrect or corrupt PCB configuration/parameter table; access the technical menu to check and reprogram, or replace the PCB if it does not accept programming. |
| A24 | PCB parameter error. | Same origin as A23: parameters of the PCB out of specification; confirm in service menu and correct or replace the PCB if it does not save/calibrate. |
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.
