I have a Glowworm 50ff that fails to light sometimes. Maybe once a week the Reset LED is solid and Burner LED is flashing fast.
Most of the time it sounds like it attempts to light itself two or three times
a successful light usually sounds like this
fan on..
click click click
woosh
then a pause,
fan on..
click click click
woosh
(reset light out, burner light green)
When it fails the failure mode is ignition lockout (according to manual). I believe I have a new PCB (green LEDs).
Is it most likely a new electrode that needs fitting? Or maybe the thermistor isn't detecting the lit pilot, hence multiple attempts to light?
I'm not a gas registered so have no intention to fix myself, just trying to get an idea of cost.
Its a 20yr old boiler so weighing up repair or replacement
Thanks!
