Combi Boiler Problem - Pressure too high
Honeysuckle777
Posts: 4 Newbie
Eek!!
I have a 7 year old Baxi combi-boiler and this morning the flame failure light was flashing, so I reset the system as per the manufacturer's instructions. Everything started working again, but I've now just noticed that the pressure guage reading is very high - at around the 3 bars mark. I tried to bleed some water out of the radiators to take this down a bit, which initially did the trick, but now the pressure is rising again!!
Help!:eek:

when that happened to me a couple of years ago with my combi-boiler it was the heat exchanger that had cracked. needed replaced and was fine after that.0

Hopefully it's something relatively simple to sort. Just having a nightmare trying to find a plumber/heating engineer who isn't booked up into the new year now!0 -
Do you have a filling loop? If so,are you sure its shut off/disconnected? Is there any water coming out of the pressure blowoff outlet (outside)Feudal Britain needs land reform. 70% of the land is "owned" by 1 % of the population and at least 50% is unregistered (inherited by landed gentry). Thats why your slave box costs so much..0

There is a filling loop - it has one of the permanently attached ones, and I have just tightened up the nut on the valve which seems to have slowed the pressure rise a bit, so thank you for that!! :T
Surprisingly, there has been no water coming from the outside overflow/blowoff outlet though. An annoyingly, the 'flame failure' thing has just happened again, so I've just had to reset. Seems there is definitely something wrong!0 -

I'm in West Lothian (Broxburn) which is about 10 miles from Edinburgh.

Forsooth...you are way too far north for me.....what exact model is it?
If the filling loop looks like a slivery braided flexible hose,then it shouldnt be permanently attached. It should be detached and caps fitted to the valve outlets. there is a slight possibility that the inlet valve is not shut off properly or may be passing a little.
The flame failure may be a separate issue.Feudal Britain needs land reform. 70% of the land is "owned" by 1 % of the population and at least 50% is unregistered (inherited by landed gentry). Thats why your slave box costs so much..0 -

if it is the heat exchanger - its not cheap
was £270 to fix a few years ago on a wocester bosch combi
good luck
hopefully it wont be that and something simple and cheap0 -
