Ferroli Domitop F 30 E PCB Ref. 39809261
When you open the hot water tap, the Ferroli Domitop F 30 E PCB (Ref. 39809261) is responsible for controlling the ignition and modulation of the burner, as well as the pump and safety features of the boiler. If this part fails, you will notice that the boiler does not start, locks out, or exhibits erratic behavior. It is compatible with boilers from the Domitop range, such as the Domitop F 24 E, Domitop C 24 E, and other models. A technician must confirm through diagnosis whether it needs to be replaced if you experience faults such as A02, F04, A23, or A24, which indicate problems with the control board.

How to check if ref. 39809261 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 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 that require diagnosis on the PCB 39809261
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 does not ignite and shows no signs.
Cause: The PCB does not supply power to the control circuits.
Check if there is mains voltage and inspect the internal fuse of the PCB before replacing it.
- 02
A click from the relay is heard, but the pump or the gas valve does not work.
Cause: The output relay does not close properly and the component does not receive power.
With the multimeter set to continuity, check if the relay is functioning before replacing the PCB.
- 03
The fault code on the panel changes every time it is reset.
Cause: The control electronics misinterpret the signals from the connected sensors and generates variable faults.
Note the codes and check if they always indicate the same sensor before replacing the PCB.
- 04
It starts the cycle and stops by itself after a few seconds.
Cause: The PCB interrupts the supply because it does not maintain the flame safety signal.
Check the ionization electrode and its wiring before considering the PCB as faulty.
Ferroli fault codes that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| 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. | This code requires technical diagnosis according to the model manual and its review. It does not confirm on its own that this part is faulty nor justifies its replacement. The causes and the exact reference must be verified before intervening. |
| A23 | PCB parameter error. | This code requires technical diagnosis according to the model manual and its review. It does not confirm on its own that this part is faulty nor justifies its replacement. The causes and the exact reference must be verified before intervening. |
| A24 | PCB parameter error. | This code requires technical diagnosis according to the model manual and its review. It does not confirm on its own that this part is faulty nor justifies its replacement. The causes and the exact reference must be verified before intervening. |
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.
