Linea Max

[GazaM]

Hi, I wonder if you can help.
I have a Linea Max, installed about 5 years ago. Until last month the reliability was great.
About 1 month ago I had to replace the expansion vessel, this was done and anti corrosion and sealer was installed at the same time.
Now I have another problem:-
When the system is cold i.e. overnight, it flags a code 04 (pressure too low) the pressure gauge is reading 1.2 BAR.
When I reset the system it works OK and will work fine until the next morning, when the same thing happens again.
Any help you can give would be much appreciated.

what kind of sealer did you put in and why?

I put in some screwfix no no nosense leak sealer, seemed a good idea at the time. My system was loosing a small amount of pressure over time and with most of the pipes under the floor (that now has tiles on it) the leaker sealer seemed a better bet.
