our 4 year old boiler has started to intermittently give a no flame
detection fault code. resetting the boiler usually cures it for a day or
two. is this a common problem on these, and is it an easy fix.


If the boiler has a permanent pilot flame, then make sure it is not being
blown out by the wind coming in the flue / chimney. This happened on ours,
and was cured by a baffle on the outside flue pipe. Pop rivet a small sheet
of galvanized steel around part of the flue to stop the wind from blowing
straight inside.

If the boiler has an electronic ignition, then check all the electrical
connections inside the boiler control panel. Vibration from running fans,
temperature changes Etc. can cause the connector to loosen off from their
mounts. The cold boiler will spark, but if it's hot it wont, sort of
scenario.

It might just be getting old and starting to feel its age. Nothing lasts
for ever, and the old bones will eventually have to give. If you're
confident and competent enough to the testing your self, then go ahead and
check all the things it could be. If you don't feel safe, or have any doubt
about your ability to handle gas connections, then get someone qualified to
check it for you.

I think all of us in the group, wish we could actually see exactly what
posters are talking about in these situations. We could probably diagnose
the problem in a couple of minutes, and fix it in a few hours on most of
them. Ah well, it's not to be. :-)

Good luck with your fix.
