Bertelli & Partners PCB for Egis NOx / Pigma NOx 24-28 FF
The control PCB governs the ignition, burner modulation, pump, and safety features of the Bertelli & Partners boiler for Egis NOX / Pigma NOX 24-28 FF. When it fails, the boiler may not start, lock out, or behave erratically, showing faults such as 3 02, 3 03, 3 05, 3 06, or 3 07. This model is compatible with several boilers, including Pigma Nox 24 FF NG, Pigma Nox 28 FF NG, Egis Nox 24 FF NG, among others. It is recommended to replace the PCB when these operational issues are detected.

How to check if ref. 65112117 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 65112117. 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 65112117 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 turn on, there is no light on the display, and nothing sounds when power is supplied.
Cause: The PCB is not sending power to the other components of the boiler.
Measure the input voltage and check the fuse on the PCB before replacing it.
- 02
The display shows a fault code that does not clear even when disconnecting and turning it back on.
Cause: The electronics block operation upon detecting a safety fault in a sensor or component.
Note the exact code and consult the manual before purchasing: it could be a sensor and not the PCB.
- 03
The boiler does not respond to the thermostat or the remote control.
Cause: The PCB does not process or transmit the heating demand signal.
Try to ignite it manually at the boiler itself to rule out issues with the external wiring.
- 04
The fan does not start when the boiler should ignite.
Cause: The relay that controls the fan from the PCB is not working.
With the boiler in demand, measure with a multimeter if voltage is reaching the fan connector.
- 05
The boiler turns on and off repeatedly without being prompted.
Cause: A fault in the PCB causes unstable signals that lead to unwanted starts.
Make sure that the connectors are properly tightened and free of corrosion before replacing the PCB.
Fault codes for Ariston that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 3 02 | Communication error. | Communication fault between the main board and the equipment's electronics; check the bus/connectors and auxiliary voltages on the PCB, and if everything is correct, the fault is in the board itself. |
| 3 03 | Main PCB fault. | Self-diagnosis detects an internal fault in the PCB; check power supplies (230 V and 5/12 V), ground, and connectors; if the error persists after the checks, replace the PCB. |
| 3 05 | Main PCB fault. | Internal fault of the PCB (control/signals); check voltages and disconnect peripherals to rule out shorts; if it reappears with correct connections, the board is damaged. |
| 3 06 | Main PCB fault. | The main control board has a hardware fault; measure auxiliary voltages and check solder joints/connectors; if the unit remains in alarm without peripherals connected, replace the PCB. |
| 3 07 | Main PCB fault. | Persistent fault of the PCB; check network stability (≈230 V), earth/ground, and continuity of connectors; if everything is correct and the code persists, the PCB is faulty. |
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.
