Hello I have a Glow worm Ultimate 50FF which I had serviced in November 2010 and has been working fine since then.
When I switch it on the radiator pump runs but the boiler is not firing up.
The flue fan is not running. As I understand the diagram on the inside cover it should run (activating the air pressure switch) before it will attempt to light.
I opened the PCB cover and there is no power on the terminals feeding the fan. Both fuses are ok. I would be grateful for any suggestions.
Andy
