    Grant External combi oil 21e burner lockout.

    SOLVED. Ashtara - I really hope that this is of help to you but I fear it won't be. At the weekend despite the weather I camped out in front of the boiler and watched it. Exciting stuff... As the property neared the set temperature (I think I mentioned it has a smart thermostat) the burner...

    Grant External combi oil 21e burner lockout.

    Hi Oilhead, thanks for the suggestions. We did have a pressure problem, that's what kicked off this whole saga! Happily that now appears ok, after the replacement of the PRV and vessel. Since then we've been chasing what I believe is only a burner issue, which currently seems to be up with the...

    Grant External combi oil 21e burner lockout.

    It was leaking out via the PRV when the failed expansion vessel was still fitted. I asked for the PRV to be replaced at the same time as the new vessel just to be sure. It was neant to be a a good thing, bit of belt and braces just to make sure the boiler was 100%! The burner led flash thing has...

    Grant External combi oil 21e burner lockout.

    Ah nuts, thought it might be a bit too good to hope for! The pressure relief valve was replaced at the same time as the expansion vessel so at least I can be confident that it will be working properly. :D

    Hi Bob, he's actually already done that without my having to ask, he has been great about it all - he's not taking the mickey I don't think and seems to be treating it more as a personal challenge than to rack up big bills. I have just sat outside (in the blimming pouring rain! :rolleyes:)...

    Blimey Andy - thanks for the incredibly fast reply!! I did see in the installation manual about that, thought it worth double checking. :) Thanks so much for all your help, will see what they say.

    Grant External combi oil 21e burner lockout.

    Hi Andy, Well I did what you suggested this week and although the flow appeared fine I gave the fire valve a quick blast with the air duster anyway as I was there. Once back together and bled the boiler is running fine but now rather than the burner locking out, the boiler control unit seems to...

    Grant External combi oil 21e burner lockout.

    Hi guys, thanks for your replies, really appreciate the input. The boiler always starts immediately on reset and whilst heating the house fires on and off merrily, it only seems to have issues once the gap between fires gets slightly longer. The last two times are what confuse me though as the...

    Grant External combi oil 21e burner lockout.

    Hi folks, once again I am in need of your expert help I am afraid! Just before Christmas my boiler was losing all pressure in about 24hours. For months it had had a very slight pressure loss that took about 8 weeks to drain but it sped up. After re-pressuring a couple of times it got even...

    Thanks oilhead. As a result of your and awowens help I was able to ask the boiler engineer sensible questions. Thanks also to the awesome engineer who spent a lot of time educating me, I now understand the boiler and the way it operates so much better than before. The issue turned out to be...

    Thank you both for your helpful replies. :) I have taken the fuel checks as far as I can, checking the pump it feels (vibration) like it is working and smell wise there is a strong oil smell now, much more there now than it was this morning which suggests to me that it is getting through. I...

    Grant External combi oil 21e not firing

    Hi, I have checked as much as an amateur can! Tank is 3/4 full, I carefully undid slightly the bleed valves on the inline filter and on the side of the pump, both immediately bled out oil, no air, bubbles, gunk or water. Are there any more checks I can do to be sure?

    Grant External combi oil 21e not firing

    Hi all, I have search about and tried a few of the suggested things that I found but none of the threads I've seen quite sum up my boilers current symptoms. I purchased my house about 9months ago and thinking it sensible, I got the boiler serviced straight away. It is a few years old (4-5?)...
