Potterton Performa 28i boiler - air pressure problem?

tukky142 · 10 Aug 2008

Hi,

I had to drain down my system yesterday to remove a rad. When I re-filled the system the boiler would not fire up. The fan neon light was flashing - (fault guide says problem with air pressure switch).
I opened up boiler to find the band clamping the fan outet elbow to the flue had snapped. Think this was casuign the air pressure problem I put a large jubillee clip around the joint to seal it back up. Still boiler will not kick into life. There is nothing blocking flue so it must be air pressure switch I presume - anyone with any other ideas?

Cant really help you there you should not attempting to repair your boiler as you are not qualified and it is a safety issue !! call a corgi engineer out

i understand what you are saying but I am an engineer by trade and to remove two screws, three elec conns and two tubes and replace the pressure switch why would I need to call someone out. If this doesnt work then I would call someone out.

if the fan is running then it is almost certainly a problem with A.P.Switch or Venturi which is where hoses connect onto fan

how can you tell if the venturi is no good? - is there a test you can do?

Out of interest exactly where does it say that?

ok to be exact the guide says check elec and tube connections, check for blockage of pressure tubes, restriction in flue and check venturi - if not any of these change pressure switch
