Had a look at top of boiler and there is like a small black screw poking out the top - is that it or is that an auto vent?
I have tried bleeding all the radiators also but still no joy.
Thanks
Hi,
Filled up with the filling loop, pressure is now at one. The boiler kicked in for a few minutes but then went off again. My house is freezing but have hot water. Any ideas?
Thanks
Hi,
My Powermax 140 boiler has no pressure and there is no light on for the burner. The lock out light has not come on.
How can I increase the pressure?
Had this problem a few years ago!
Many thanks for all replies and relevant links!
