This boiler suddenly stopped working, there have been no problems or indications, the orange light does now not come on. I have powered down and restarted to no avail, found and checked the 2 amp fuse. what is the significance of this orange lamp? Is there a reset button, I found a brown coloured component on the bottom of the electronics housing, but it doesn't move, is it a switch? how does it turn or should it press?
Any help would be appreciated

Thanks Phil,

You pointed me me the right direction

Looks like one of the valves (heating)has quit, because if I reset and manualy move the lever on the valve the heating fires up

Ordered one so hopefully will sort the problem

The orange light is called the "demand" light and means one, or both, of the thermostats is asking for the boiler to light up.

There is a reset button located in the bottom of the casing. There should be a sliding panel with some basic operating instructions on it. Slide this out and it exposes a hole in the casing through which the button can be pressed.
