CodeWhat does it mean?Cause and diagnosis (this part)
03Lack of pressure in the heating circuit.If the water pressure switch (122450050) does not close even though the system is >1 bar (membrane/switch faulty or defective connections), the electronics interpret insufficient pressure and lock with 03. Verify by increasing the pressure to 1.2–1.5 bar and measuring the continuity of the pressure switch: it should close under pressure; if not, replace it.
