Does the red status led in the centre of the control board come on when hot water is drawn? You need to remove ONLY the front decorative cover to see the control board, two fixing screws at the base of it. If not the boiler won't fire when the CH is off.
The trigger for this is a pressure switch, replacement of which is beyond DIY scope.

Hi - hope someone can help. I have a VOKERA EXCEL 80SP combi boiler and been without hot water/central heating for two days. The pilot light is on, the fan is on, but boiler not triggering once the hot water tap is turned on.
Hopefully someone come to look at it today but hoping for some advice. Anyone else had this problem?
Thank you.

there is a zoneing valve thats suppose to be in the line to keep this from happening, might even have a check valve either way which ever one you have is bad and should be changed with a new one
