pressure problem code being shown is f.75?
The boiler pressure is about 1.5-1.8 but when the heating is put on the boiler does not seem to be able to take the water and the heating system on at the same time. Everything seems to shut down thus showing us the code f.75. what can i do as winter is fast approaching.
