My ideal elan 2 boiler ignites from cold with no problem. However after a period
anything from an hour to longer it refuses to fire up. After a period of time
obviously cools down it will then fire up again.
I initially thought there was a problem with the over heat stat, although this
need to be reset as it does not pop up. However I replaced it with some success
as this morning the boiler fired constantly. However the same problem has
again. I can hear the air pressure switch clicking in and the fan is running but
ignition. Was wondering if it could be a pump problem, maybe the water can not
from the boiler quick enough and its overheating and then is cutting out until
down. However why doesn`t the overheat stat click in ?
Have phoned a round some heating engineers so far none want to know this side of
Would a new pump solve the problem or is my conclusion wrong? Don`t fancy being
consistent heat until after Xmas.
Any help appreciated
Very unlikely to be the pump - if that fails, the overheat stat *will* trip
and the boiler will then do nothing at all.
Does your boiler have a row of (maybe 3) LEDs which come on in sequence
during the firing cycle? If so, how many of these are lit?
The boiler is clearly *trying* to fire - otherwise the fan wouldn't run.
Depending on how far it's getting through the firing cycle you could have a
problem with the pressure switch, pilot solenoid, ignition system or main
gas valve. It's also possible - perhaps even likely in view of the fact that
it seems to be temperature dependent - that you could have some iffy
electronic components on the control board.
Agree with you here if the pump failed completely but the pump is at a guess 13
its pumping but I wonder if its not pumping as efficiently as it once was and
rate through the boiler has been dreuced therefore raising the temperatire
Have put in a new pressure switch and I can hear that switching. The PCB is new
as well so
doubt that is at fault.
I had a similar problem and it was down to the fan ,it did this for a while
then eventually failed completely,I sourced a second hand one from
