Potterton combi problems

[ferkh10]

I have a Potterton Combi boiler and there is no power to it. I have checked the obvious things, changed the main fuse, checked the electrical power to the boiler etc.

There are no lights showing on the front of the boiler.

Is there likely to be a simple solution?

Any help would be greatly appreciated.

Is there an overheat reset button on the boiler? Possibly on the underside to the right?
