Boiler pressure has been fine since engineer removed blockage in pipe in boiler connected to expansion vessel. CH stat on boiler (not room stat) turned fully up & pressure ok now. Thanks for all posts to help resolve this issue as we felt we were being forced by insurance company to have...

UPDATE Different engineer has been. Sorted LF error code by clearing condensation pipework within boiler. He drained boiler, checked pressure in vessel & added more air as not enough in. He wasn't satisfied with this though, as he was not happy that pipe from vessel seemed to be blocked. He...

Thanks for you comment, however I have insurance policy which covers the boiler. The fact is the engineer has not dealt with the expansion vessel pressure correctly, which has been stated on this post by other members and I totally appreciate their input. And refusing to replace a PRV which was...

Thanks for diagram & explanation, now understand concept. Will get this checked properly tomorrow. Will update post once done. Cheers.

Thanks for response. So i don't misunderstand you, the engineers are checking pressure in vessel directly by using gauge on it. They are doing this when system pressure gauge is showing 1bar, ie they have not drained system. Would this mean that pressure reading they are getting is false on...

Would it be good idea to change pipe attached to expansion vessel & check its pressure with boiler drained as next step to resolve rising pressure problem? At the moment getting no error code on boiler and have turned down boiler CH stat to very low, so pressure only rises to 2.5 bar as boiler...

But the internal one was not failed ! Just the communication pipe blocked and these can usually be unblocked in 20 min. But you get very dirty and wet if you don't do it properly! Is this the pipe from expansion vessel you mean. If so 1st engineer said he cleaned it when he had boiler...

Did they check the exp vessel pressure with the boiler drained and drain or vent open ? I know you have had a new one fitted but it could be flat/faulty. Also just because the pipes and rads get hot there could (and i mean could) be a restriction somewhere (doesn't mean you need a power flush...

also 2nd engineer who called out was highly recommended. In last hour another engineer has been out who has no idea why pressure is rising. as you say its not difficult to diagnose when in front of boiler, so why cant any of these engineers see what the problem is. Any advice will be greatly...

thanks for reply, will either of those issues have possibly anything to do with pressure rising?

Hi can anyone help me with a problem with my IDEAL ISAR HE30 boiler. When CH is on pressure on gauge rises to above 3 bar within 15mins & then leaks via PRV & out thru pipe outside, needing to refill to 1bar when cold. So far had 2 different engineers, 1st said faulty pressure gauge, then he...
