I have a Linea 28 which first thing on a morning the pressure gauge is zero and the fault code 04 is flashing. To get it working, I have to put a little water in and reset, no problems. However once the boiler is warmed through say 1 hour the pressure reads 3bar? Once the boilers off again and cold it drops to zero. Whats going on. Any help appreciated.
