CodeWhat does it mean?Cause and diagnosis (this part)
A04Water pressure switch alarm.The water pressure switch does not close/open due to insufficient pressure or a fault, so the PCB does not receive its signal and triggers A04. Check pressure on the manometer (≈1–1.5 bar) and verify continuity/functionality of the pressure switch with a multimeter under pressure.

Verify the reference 20046189 printed and ensure your model is on the list of compatible ones; also compare the connections with the original part.
What is it used for?
