Question 1

What does fault code 3 03 mean in Chaffoteaux?

Accepted Answer

Main PCB error The main electronic module (PCB) does not pass its internal self-diagnosis; check power supply voltages 230 Vac/5–12 Vdc, fuses, and visible damage on the board. If the issue persists with peripherals disconnected, replace and parameterize the board ref. 030004256707.

Question 2

What does fault code 3 05 mean on Chaffoteaux?

Accepted Answer

Main PCB error. Self-diagnosis detects a fault in the internal circuits of the PCB (outputs/relays/logic). Check 5–12 Vdc rails and unloaded outputs; if the error persists when isolating peripherals, replace and parameterize the PCB 030004256707.

Question 3

What does fault code 3 06 mean in Chaffoteaux?

Accepted Answer

Main PCB error Internal anomaly of the PCB (e.g., watchdog or power supply). Check stabilized voltages, fuse, and soldering; if after resets and disconnection of loads the fault persists, replace/parameterize the PCB 030004256707.

Question 4

What does fault code 3 07 mean in Chaffoteaux?

Accepted Answer

Main board error Additional internal fault detected by the main board's self-diagnosis. Confirm power supplies/damage to the PCB and rule out shorts in peripherals; if not resolved, replace and configure the 030004256707.

Code	What does it mean?	Cause and diagnosis (this part)
3 03	Main PCB fault	The main electronic module (PCB) does not pass its internal self-diagnosis; check supply voltages 230 Vac/5–12 Vdc, fuses, and visible damage on the board. If the issue persists with peripherals disconnected, replace and parameterize the board ref. 030004256707.
3 05	Main PCB fault	Self-diagnosis detects a fault in the internal circuits of the PCB (outputs/relays/logic). Check 5–12 Vdc rails and outputs without load; if the error persists when isolating peripherals, replace and parameterize the board 030004256707.
3 06	Main PCB fault	Internal anomaly of the PCB (e.g., watchdog or power supply). Check stabilized voltages, fuse, and solder joints; if after resets and disconnection of loads the fault persists, replace/parameterize the PCB 030004256707.
3 07	Main PCB fault	Additional internal fault detected by the main board's self-diagnosis. Confirm power supplies/damage to the PCB and rule out shorts in peripherals; if not resolved, replace and configure the 030004256707.
