What does the fault code EA mean in Biasi?

Flame not detected (absence of ionisation signal). If the coil of the gas solenoid valve (87167077040) is open, shorted, or not energized, the valve does not open and gas does not reach the burner; check voltage at terminals during ignition attempt and measure continuity/ohmage of the coil.

What does the fault code EA 234 mean in Biasi?

EA with additional code 234: electrical fault of the block/gas valve (coil disconnected or faulty). An open/short-circuited coil of the solenoid valve or its wiring causes the 234 under EA; check continuity of the coil 87167077040 and the harness, and replace if out of range.
