Ariston Egis NOx / Chaffoteaux Pigma NOx 24-28 FF PCB - Bertelli & Partners
When you turn on the tap or activate the heating, the Ariston Egis NOX / Chaffoteaux Pigma NOX 24-28 FF PCB (control board) takes care of controlling the ignition, the modulation of the burner, and the boiler pump. If this part fails, you will notice that the boiler does not start, gets locked, or exhibits erratic behavior, potentially displaying fault codes such as 3 02, 3 03, or 3 06. This model is compatible with Ariston Egis NOX and Chaffoteaux Pigma NOX boilers, among others. It is recommended to replace it when these symptoms or errors occur.

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 and the control panel does not respond.
Cause: The PCB controls both the ignition and the panel. If it fails, the boiler does not respond.
Check that the boiler is receiving power and inspect the fuse on the PCB before replacing it.
- 02
The boiler locks out without any leaks or noises.
Cause: If the blockage does not have a visible mechanical cause, it is usually a problem with the electronic control of the PCB.
Note the lock code each time it occurs; if it changes without a clear pattern, it is likely an electronic fault.
- 03
The boiler works well for a while and then fails intermittently.
Cause: An intermittent fault on the PCB, due to a solder joint or component that overheats, causes faults that appear and disappear.
Observe if the fault occurs more when the boiler is hot or just turned on, as this helps to identify the problem.
- 04
After a power outage, the boiler does not start on its own and needs to be reset manually.
Cause: Some PCBs become unstable after a voltage drop if their recovery circuit is not functioning properly.
Perform a complete reset from the remote control and check if the problem recurs after several controlled power outages.
Fault codes Chaffoteaux that this part resolves
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 3 02 | The PCB is not communicating properly with the rest of the equipment. | The main PCB is not communicating properly with the rest of the equipment. Check the cables and connectors, as well as the auxiliary voltages on the board. If everything is fine and the problem persists, the board is to blame. |
| 3 03 | Internal fault in the main PCB. | The PCB has detected an internal fault. Check that it is receiving 230 V properly, and that it also receives 5 and 12 V. Verify the ground connection and the connectors. If the error persists after all this, you need to replace the PCB. |
| 3 05 | Internal fault in the main PCB. | The PCB has an internal defect in the control or signals. Check the voltages and disconnect the peripherals to see if there are any short circuits. If the fault persists with everything properly connected, the PCB is damaged. |
| 3 06 | Hardware fault on the main PCB. | The main PCB has a hardware issue. Measure the auxiliary voltages and check the solder joints and connectors. If the unit remains in alarm even when no peripherals are connected, the board needs to be replaced. |
| 3 07 | Persistent fault on the main PCB. | The PCB keeps failing. Check that the power supply is stable (around 230 V), that the grounding is correct, and that the connectors have continuity. If everything is correct and the fault 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.
