Mend Potterton Prima F Boiler

How can I fix a Potterton Prima F Boiler?

I have a Prima F Boiler. The problem I am having is when I call for either hot water or central heating the fan kicks in for around 10 secs then stops. 20 Seconds or so later it starts again. This action continues but with no flames, resulting in no hot water.

I have spoken to my friend he believes that it may be the flow switch. Can anyone else give me light o my problem.

after fan you have air pressure switch then ignition clicking and gas so you'd work from there,

poss a.p.s not working or venturi blocked or cracked pipes or broken ignition or faulty gas valve solenoid etc.

few things to check and in RGI area only so time for an engineer
