    Baxi solo 2 pf50 - intermittent ignition problem

    Here's a puzzler for you. We have the above boiler, and when heating/hot water is called for after the boiler has been off a while and cooled, then it can take an age to light the main burner. Once warm, it generally lights ok if there is another call for heat. Since this problem started...

    Noisy Baxi fan?

    Baxi solo Pf2 50 - has had recent new PCB and pilot kit to solve non lighting burner. Has recently developed a noise, that I would guess is fan related, as it is a low whistle tone (although thats not a very good description..) Its intermittent, if the boiler hasn't been on for a while and...

    Baxi solo 2 Pf 50 - Burner fails intermittently help plse!

    After an hour or so looking at it, the next stage is to replace the pilot as suggested above! Engineer reckons the pilot is in the wrong place and not necessarily cancelling the call for the pilot. It is also not lighting the burner properly (when it does it at all) as it lights one...

    Baxi solo 2 Pf 50 - Burner fails intermittently help plse!

    if it helps, an electrical spark can be seen around the pilot, thru the viewing window. The pilot is definitely present and looks strong, but there is a little blue spark appearing quite frequently

    Baxi solo 2 Pf 50 - Burner fails intermittently help plse!

    thanks Corgigazza. The problem seems to occurr when the boiler has not been on for a while (i.e previously reached temp, shut off normally, then is called back into service). Today, it was running okay, then we went out for 4-5 hours. I didn't touch the heating, leaving it to run as...

    Baxi solo 2 Pf 50 - Burner fails intermittently help plse!

    Well the saga continues. Engineer called to replace PCB on Wednesday. Was working when he left. By 11pm that night it had gone off again. Same sort of issue, wouldn't fire the main burner, it sometimes clicked on and then straight off. Buzzing noise which happened when starting from...

    Baxi solo 2 pf - several tries to ignite main burner

    Have had PCB on boiler replaced last week, as it was buzzing when it started up and was not lighting the main burner. Now it will start up, but when its not been on for a while it takes a few tries to light the main burner (clicks on, then off immediately but after 3-4 tries fires). It...

    Baxi solo 2 Pf 50 - Burner fails intermittently help plse!

    Thanks for the advice, i will discuss it with him. I should have mentioned that if we turn the boiler off completely at the wall switch, then turn it on, we get about 10 seconds of 'buzzing' from the PCB area, before any action at all - if that makes a difference. When he first looked at...

    Baxi solo 2 Pf 50 - Burner fails intermittently help plse!

    The engineer who looked at it yesterday thinks its the PCB and is fitting one tomorrow - should I be worried that this won't solve the problem!? Noting these are £150+

    Baxi solo 2 Pf 50 - Burner fails intermittently help plse!

    Problem with the above boiler, in that when it fires up after being off for a while it can sometimes get all the way through the sequence up to lighting the burner (i.e boiler, fan and pilot indicators lit, a pilot flame visible) but then not actually light the burner. If left for some time...
