Hi,
I have the above boiler and am experiencing the following :-


When the timer calls for water the boiler will not ignite. I can hear
the ignitor clicking but there is no ignition and the 'lockout' light
comes on. If I reset the boiler as per instructions it works OK -
igniting multiple times as required until the next new timed period,
when the above sequence has to be performed.


I have check the pump and motorised valves and they are OK so I suspect
the boiler. I rang Baxi who have quoted £219 for a repair. I stated
that the boiler was 3.5 years old and already on its second PCB so I
was reluctant to spend another £219 on it just yet.


Does anyone have any experience with this problem ?


Any advice gratefully recieved

No particular order:

No gas - PCB, gas valve, gas supply (yeah right) or blocked injector.
No flames - spark electrode shorting (but still ticking), igniter pylon
broken, electrode missing or misplaced, debris near ignition area
No detection of flames - lead, pylon and electrode (maybe same as above).
or PCB.

As you can see the PCB mightn't be the cause.

Thanks for the reply Ed,

What I can't understand is that if it's not the PCB, why does resetting
the boiler make it work ?

I am going to take the firefront off this weekend and see if I can
detect any of the problems that you've mentioned.

It's an intermittent fault give it another go and you get lucky.
This means that it's not likely to be something hard like a broken wire or
a bad gas valve.

Thanks again Ed,

I'll give it a good clean and disconnect / reconnect all the electrical
connections.

Id recommend that you test the polarity to your BBU. If ok, ensure that your getting 240v to the appliance..If your getting a spark at the pilot and no flame, check if there is gas to pilot, at time of ignition..you have an oxy pilot and if there is fluff-lint, around the pilots air port then it will not light. try these checks ...post me the results ...good luck....ps you have to be gas qualified to work on any gas appliance

Hi I have the exact same problem but we are in 2018 and biker is old. I do not
see a resolution confirmation to the above. Could thermostat sensor 232215 be
the culprit?
