Hi, I was wondering if some kind person could give some advice on an ongoing problem we are having with our boiler. When you run the hot tap or switch on the central heating the boiler very rarely fires straight away. It makes a whirring noise over and over again as it attempts to light . Sometimes it lights after only a few attempts, but other times it continues to try but the fault on Fan or Flue neon begins to flash. Normally it will light..... but this can take some time! This is obviously more of a pain with the hot water because it can take a couple of mins to get any. Occasionally you will have to turn the tap/central heating off and leave it for a few mins before trying it again. Any suggestions on what it may be/cost to repair/if i can do it myself or need to get someone in? Thanks.

sounds like it needs a service 
It had a service about 6 months ago. We mentioned this problem to the plumber but he wasn't sure exactly where the problem was as the fan and flue appeared to be fine. It was working ok that day. Hence trying to see if anyone else has come across this issue

Air pressureswitch would be the most likely or blocked/damaged venturi.
If it was getting into ignition sequence the left hand neon only would flash
