Hi all,

Any help much appreciated with a LED illuminating showing "ignition lock
out" warning
when i try to run the hot water or turn on the heating. The water warms
briefly
then turns cold after an audible click is heard. The fan, pump and
everything else seems
to continue to run,

any advice much appreciated ,

Ideal do a wide range of boilers, my advice would be to be a bit more
specific ... what boiler is it ?
