I have adjusted the boiler water pressure at 1.5 as instructed by the engineer but every time the central heating comes on it increases to 2.5 and error E40 (water pressure too high) comes up.
But when I bleed the radiators to decrease the pressure after a while the error E37 (water pressure to low) comes up.
It is happening every couple of days.
Keston won’t come and have a look as it is over 10 years old boiler.
Any helpful suggestions will be much appreciated.
