Vokera HE Compact- Only fires when the front cover is off
ARWadworth
When HW or CH is called for the boiler starts to make its normal firing up
noises (I assume it is the fan) but never actually fires. There is no
ignition sequence or spark.
I took the cover plate off the burner front to have a look at the spark and
with this cover off the boiler fires. Replace the cover and the boiler stops
burning. The fan stays running.
The flue is clear of any debris and I changed the air pressure switch and
checked the tubes for damage. No change.
I realise that the boiler fires with this cover off as air is getting into
the burning chamber through the front and not through the flue.
So where do I look next to find the fault?

Is there an obstruction inside the flue where the sensing tubes enter
the airstream? This could be down to corrosion within the venturi.
Alternatively leaves or cobwebs obscuring the air inlet or flue
outlet. (Other causes not discounted)

==================================
A remote possibility...
My boiler gave the same symptoms for a quite simple fault. The boiler
would only fire up with front cover removed and it did this consistently.
Every time the cover was replaced it failed to fire up. When I removed
the cover to try again I noticed that the small ignition lead was
sparking against the boiler chassis and no spark was reaching the correct
ignition point. The ignition lead was being partly trapped when the cover
was replaced. The strange thing is that the insulation on the ignition
lead appeared to have broken down spontaneously - no physical damage
visible. In my case the lead was able to spark normally until it was
pushed against the chassis, so you might try moving your ignition lead
about to see if it does the same.

Hint: the web portal you are using likes to promote questions from a
decade ago as a current topic.

interface is. I'm not totally sure if they even care. After all they pass
this place off as theirs, when it is clearly a Usenet group and these have
been around for longer than the web has.
If anyone wants to use it legitimately first try to figure out if the post
is very old if possible then quote part of it in your reply, at least that
way people here will know what its about.
Nobody is going to go on that web site to fiddle with the interface to do
what they can do perfectly well with software meant for the job of using the
newsgroups.
