Main PCB Chaffoteaux Alixia 24 FF Ref. 65109313 05
The main PCB Chaffoteaux Alixia 24 FF, with reference 65109313-05 and manufactured by Comelit, is a key component that controls essential functions such as ignition, modulation, the pump, the fan, and communication with the control panel. When this part fails, the user may experience faults such as "Eeprom Error," "Boiler PCB - User Interface PCB Communication Error," or "Main P.C.B. error," which manifest as operational issues with the boiler. This PCB is compatible with several models, including Alixia 24 FF, Alixia CF/FF, Pigma CF/FF, Talia CF/FF, and Urbia CF/FF, among others. It is recommended to replace it if the mentioned errors occur or if the boiler does not respond properly.

How to check if ref. 65109313 05 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 65109313 05. 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 65109313 05 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 is completely dead, with no pilot light or display, although there is power in the house.
Cause: The PCB does not activate its own internal electronics, so it does not give any signal even though it receives power.
Check the fuse on the PCB and use a multimeter to verify that 230V is present before declaring it faulty.
- 02
It locks up with a code that does not match any real issue with water, gas, or drainage.
Cause: The PCB processes the signals from all the sensors; if its electronics fail, it can display false faults.
Reset and note if the fault code changes between attempts: that points to the PCB, not the indicated component.
- 03
The buttons on the panel do not respond or respond with a delay.
Cause: The microcontroller on the PCB is the one that reads the pulses; if it degrades, it loses reactivity.
Cut the power for 2-3 minutes and try again before concluding that the PCB is faulty.
- 04
The pump or the fan does not start even though the relay can be heard activating.
Cause: The PCB sends the command but fails to deliver the output voltage to the component.
Measure with the multimeter if there is voltage at the output connector when the pump or fan should be activated.
Fault codes Chaffoteaux that this part resolves
| Code | Fault | Diagnosis and solution |
|---|---|---|
| EEPROM error | EEPROM memory fault on the PCB. | The integrated EEPROM on the main PCB is corrupted/damaged; check for stable voltages on the board and, if the error persists after resets, confirm with a reader/programmer or replace the PCB. |
| Communication error between boiler PCB and user interface board | Communication fault between the main PCB and the user panel. | Interruption/noise in the data bus between the main PCB and display due to damage in the PCB or connectors; check the flat cable, 5 V on the interface, and TX/RX signals; if they are correct and the display is good, replace the PCB. |
| Main PCB fault code | Anomaly in the main PCB. | Self-diagnosis detects a general fault in the PCB (5/12 V regulators, microcontroller, relays); check 230 V input, fuse, and low voltages; if missing or shorted, replace the board. |
| 3 02 | Communication error (GP–GIU). | Communication fault between the main PCB (GP) and the user interface; after checking wiring/connectors and 5 V, if there is no signal on the bus or the fault persists with a tested display, the cause is the PCB. |
| 3 03 | Main PCB fault. | The control electronics detect an internal fault in the PCB (e.g., relays/outputs or supervision); confirm by measuring service voltages and signals; if abnormal or intermittent, replace the board. |
| 3 05 | Main PCB fault. | Internal fault of the main PCB; check 5/12 V sources and the condition of relays/driver; if the measurements are not correct or the error persists, replace the PCB. |
| 3 06 | Main PCB fault. | Fault detected in the PCB (control components/circuits); check low voltage supply and circuit continuity; if there are deviations, replace the board. |
| 3 07 | Main PCB fault. | Self-diagnosis identifies a critical anomaly in the PCB; check voltages/outputs and, if it persists after reset and peripheral check, replace the PCB. |
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.
