Bertelli & Partners PCB Chaffoteaux Ariston Levia NOx 24 FF Ref. 65109475
When you open the tap or turn on the heating, the Bertelli & Partners Chaffoteaux Ariston Levia NOX 24 FF PCB controls the ignition, burner modulation, pump, and safety features of your boiler. If this part fails, the boiler may not start, become blocked, or exhibit erratic operation. This board is compatible with the Levia NOX 24 FF and 28 FF models, as well as the Altis NOX 24 FF and 28 FF, among other boilers in the range. A technician must confirm through diagnosis whether it needs to be replaced upon detecting any of these issues to restore the boiler's operation.

How to check if the reference 65109475 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 65109475. 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 65109475
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 domestic hot water comes out cold, even though the heating is working.
Cause: Each circuit is activated by a different relay on the PCB; if one fails, that circuit stops receiving commands even though the other one works fine.
Check that the three-way valve or the circulator of that circuit receives power when it shouldn't before replacing the entire PCB.
- 02
The boiler restarts by itself from time to time, or the display flashes without you having done anything.
Cause: An unstable power supply on the PCB causes micro-cuts that reset the electronics.
Check that the mains power supply is stable, without drops, before attributing the fault to the PCB.
- 03
The boiler starts the sequence but the fan or the pump do not activate, although the rest proceeds normally.
Cause: The output that activates that component may lose signal even though the PCB continues to function for everything else.
Measure if there is power at the connector of that component at the moment it should activate, before replacing the PCB.
- 04
The boiler does not respond to any commands: neither to the boiler control nor to the thermostat in the house.
Cause: The input that collects the heat demand goes through the PCB.
Do not force, hit, or bridge the component. Request a technical check according to the equipment manual before deciding on its replacement.
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.
