Boiler problem

[Gazzarooney]

Hi Guys,

I have a "Powermax 155x" Boiler. I keep having a repetative problem with it. All pressure is lost in the system and the boiler goes into "lockout" and the hot water and heating shuts down.
If i open the valve to increase the pressure again and turn the boiler off then back on it fires up and contiues as normal, but about 5 hours later same ting happens.
There is also water dribbling out of the pipe that comes out of the boiler through the wall to out side, think this is some kind of overflow pipe or something.

Any ideas

sounds like you have got a problem with your expansion vessel and your prv

I would call Baxi as they now have taken the spares etc over. Would be worth having the flue inspected at the same time as a BG customer died after calling them out 9 times complaining of fumes.
