Ferroli optimax anyone knows what fault D01means?

And D02. Heat picture is showing over radiator but the burner is not coming on and the boiler is very new.

im no expert mate but i dont think D01/D02 are faults.D01 shows when CH is on but the burner is between burns, and D02 shows when CH is on but you have just run the hot tap. If everything is working ok, they are quiet normal.
