Danesmoor 15/19 intermittent immediate lockout

Morning all.

Another lockout issue with my elderly (Yr 2000) Worcester Danesmoor 15/19 oil boiler.

It runs fine most of the time, but on restart sometimes it just doesn't fire. It doesn't seem to happen mid-run, just when it is restarting.

The motor and fan runs, and I hear one click (from the control box) where usually it would fire up, but it just doesn't. I assume the photocell is then correctly shutting it down. Usually after a few goes of resetting it eventually fires. This is happening every few days, so not all the time, but still fairly regular.

To me it seems like the spark is maybe not working correctly? In which case which part would need replacing?

Other info:
  • Plenty of oil in tank
  • New coil a few weeks ago
  • Serviced in October this year, new nozzle, pump pressure, flue gasses all fine etc.
Many thanks
