Power supply fault in the gas solenoid valve. The gas valve (block 122062850) does not open or its coil is open/stuck, so no gas reaches the burner and the PCB locks due to the absence of a flame. Check by measuring if a command reaches the solenoid valve during ignition and the resistance of its coils; if there is a command and the coil is out of range or does not open, replace the valve.
