The boiler has stopped working (no CH or DHW but fan and pump working) the manual says to check the air pressure switch is functioning OK.
The ventura (the white one) was brittle and completely shattered when I removed the tube and now needs to be replaced. I'm presuming the red one also needs replacing and planned to change both but cannot see how one would do this without having to remove the fan assembly from the combustion chamber.
Is this now a job for an engineer?
The APS tested OK with a mulitmeter by the way as did the overheat stat. I could only check the flue from the outside and could see no obstruction.
