Ferroli Elite PCB Ref. 39803410
The control PCB manages the ignition, burner modulation, pump, and safety features of the boiler. If it fails, the boiler may not start, become locked, or exhibit erratic operation, displaying fault codes such as F36, F10, F22, F25, or F8. This Ferroli Elite Electronic Board, with reference 39803410, is compatible with models from the HAWK II, FLUSS 20 EL CE, NEF96, NEFA20CE, NEWELITE, and OPTIMA (1001, 2001, 201, 601, 701, 801, 901) ranges, among others. It is recommended to replace it when the mentioned symptoms occur or the associated fault codes are detected.

How to check if the ref. 39803410 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 39803410. 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 39803410 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 does not ignite, there are no lights on the thermostat or on the unit.
Cause: The PCB is not sending current to the control circuits.
Measure with a multimeter if there is power at the input of the PCB and check the fuse before replacing it.
- 02
The boiler starts but shuts down after a few seconds.
Cause: The electronics stop the cycle because they do not correctly validate the ignition or flame signal.
Check that the ignition and detection electrode wires are properly connected to the PCB before replacing it.
- 03
The temperature controls are not working or are stuck at a certain value.
Cause: The push buttons or the microcontroller on the PCB do not receive commands from the user.
Try resetting the boiler from the main switch and check if the controls start working again before replacing the PCB.
- 04
An intermittent fault code appears that does not occur at the same time every time.
Cause: This is often caused by damaged solder joints or traces on old PCBs, which fail depending on temperature or vibration.
Observe if the fault occurs more when the boiler is cold or just turned on; that pattern helps confirm that the problem is with the PCB.
Fault codes for Ferroli that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F36 | PCB anomaly | PCB fault (VMF7 ref. 39803410). If it persists after a reset, the manual instructs to replace the board; check supply voltages, grounds, and connectors before replacing it. |
| F10 | Microprocessor anomaly | Internal CPU error on the PCB; if the reset does not clear it, the official instruction is to check and, if necessary, replace the main board. Verify supply, neutral/ground connection, and network stability before replacement. |
| F22 | Microprocessor anomaly | Same diagnosis as F10 in the NEW ELITE series; if after disconnecting/connecting it persists, check/replace the PCB. Confirm voltages and grounds; if they are correct and the fault continues, replace the PCB. |
| F25 | Software anomaly | Software error on the PCB; the official procedure indicates to reset and, if it persists, check/replace the main board. Verify power supply and wiring; if the fault repeats, replace the PCB. |
| F8 | No flame after the ignition phase | Among the documented causes is "control board anomaly"; a defective PCB may not manage spark/ionisation or output to the gas valve. Check the electrode, grounding, and wiring; if they are correct and there is no command/output from the PCB, replace it. |
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.
