Question 1

How do I know if this PCB is for my boiler?

Accepted Answer

Check the reference 65109313 05 printed and ensure your model is on the list of compatible ones; also compare the connections with the original part. It is a Chaffoteaux / Ariston Thermo piece (OEM PCB, with no third-party component manufacturer indicated).

Question 2

What is it used for?

Accepted Answer

The PCB controls the ignition, modulation, sensor readings, and safety features of the boiler.

Question 3

Is the boiler not igniting, locking out, or is the control board unresponsive?

Accepted Answer

After ruling out mains voltage, fuse, and connectors, a damaged PCB causes lockouts, blackouts, or erratic display. Repair the external cause before installing the new one.

Question 4

Which models is it suitable for?

Accepted Answer

Part shared by various models (see Compatibility). If your model does not appear, send us a photo of the marking and we will confirm it.

Question 5

Installation and recommendations

Accepted Answer

After installation, a technician must adjust the service parameters (type of gas, power settings) and check combustion and safety features.

Question 6

What does refurbished mean and what coverage does it have?

Accepted Answer

Part removed from a boiler out of service, inspected and tested. Includes 1-year warranty and 14-day return policy. Delivery within 2–4 working days in the EU.

Question 7

What does the Eeprom Error code mean on Chaffoteaux?

Accepted Answer

EEPROM memory fault on the PCB. The EEPROM integrated in 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.

Question 8

What does the fault code Communication error boiler PCB - user interface PCB mean in Chaffoteaux?

Accepted Answer

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.

Question 9

What does the Main P.C.B. error code mean in Chaffoteaux?

Accepted Answer

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 there are shorts, replace the PCB.

Question 10

What does fault code 3 02 mean on Chaffoteaux?

Accepted Answer

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.

Question 11

What does fault code 3 03 mean in Chaffoteaux?

Accepted Answer

Main board error. 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.

Question 12

What does fault code 3 05 mean on Chaffoteaux?

Accepted Answer

Main PCB error. 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.

Question 13

What does fault code 3 06 mean in Chaffoteaux?

Accepted Answer

Main board error. Fault detected in the PCB (control components/circuits); check low voltage supply and circuit continuity; if there are deviations, replace the board.

Question 14

What does fault code 3 07 mean in Chaffoteaux?

Accepted Answer

Main board error. Self-diagnosis identifies a critical anomaly in the PCB; check voltages/outputs and, if it persists after reset and peripheral check, replace the PCB.
