Question 1

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

Accepted Answer

Verify the reference 740190001707 printed and ensure your model is on the list of compatible ones; also compare the connections with the original part.

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 fault code 3 01 mean on Ariston?

Accepted Answer

EEPROM display error The EEPROM on the main PCB is damaged or not reading/writing correctly, preventing initialization. Check 5 V/12 V on the PCB, solder joints/continuity of the EEPROM, and reprogram or replace the PCB if necessary.

Question 8

What does fault code 3 02 mean in Ariston?

Accepted Answer

Communication error Communication bus fault of the PCB (BridgeNet/GP‑GIU) with the display or peripherals due to a fault in the PCB circuit. Check wiring/power supply and bus signals; if they are correct, the cause is in the main board.

Question 9

What does fault code 3 03 mean in Ariston?

Accepted Answer

Main board error. Self-diagnosis detects a fault in the control electronics (CPU/timing/regulators) of the PCB. Check the stability of the power supply, reset/oscillator, and if external factors are ruled out, replace the board.

Question 10

What does fault code 3 05 mean in Ariston?

Accepted Answer

Main PCB error Generic fault of the PCB (logic or control stage) that prevents safe operation. Check the voltages of the board, tracks/relays/triacs, and replace the board if the issue persists.

Question 11

What does fault code 3 06 mean in Ariston?

Accepted Answer

Main board error Generic repeated fault in the board's electronics (microcontroller/supervision). Check power supply, references, and control hardware; if there is no external cause, replace the PCB.

Question 12

What does fault code 3 07 mean on Ariston?

Accepted Answer

Main board error Internal error of the main board detected by self-diagnosis. Check sources/clock and ensure there are no shorts in outputs; if everything is correct, replace the PCB.

Code	What does it mean?	Cause and diagnosis (this part)
3 01	EEPROM display error	The EEPROM on the main PCB is damaged or not reading/writing correctly, preventing initialization. Check 5 V/12 V on the PCB, solder joints/continuity of the EEPROM, and reprogram or replace the PCB if necessary.
3 02	Communication error	Communication bus fault of the PCB (BridgeNet/GP‑GIU) with the display or peripherals due to a circuit fault in the PCB. Check wiring/power supply and bus signals; if they are correct, the cause is in the main board.
3 03	Main PCB fault	Self-diagnosis detects a fault in the control electronics (CPU/timing/regulators) of the PCB. Check the stability of the power supply, reset/oscillator, and if external factors are ruled out, replace the board.
3 05	Main PCB fault	Generic fault of the PCB (logic or control stage) preventing safe operation. Check voltages on the board, tracks/relays/triacs, and replace the board if the issue persists.
3 06	Main PCB fault	Generic repeated fault in the PCB electronics (microcontroller/supervision). Check power supply, references, and control hardware; if there is no external cause, replace the PCB.
3 07	Main PCB fault	Internal error on the main PCB detected by self-diagnosis. Check sources/clock and ensure there are no shorts in outputs; if everything is correct, replace the PCB.
