Potterton Not Igniting

[gibson8206]

This morning of all cold mornings my Potterton Prima F refuses to fire up. This in CH, HW or both combinations.
The pump is revolving.
If anybody can help I'd be very pleased to try any suggestion.

Thanks,

Gibson8206.

Has this boiler got a reset button?

Thanks for the fast reply 75pete. Not too sure, but there is a red plastic screw looking projection I can see when I take the underneath cover off.

Thanks seco services and 75pete. Pushed button and 5 minutes later the boiler fired
I guess it tripped out for a reason so it may be a good time for a service. Only recently moved into the house so not sure when the boiler was last tweaked.
Thanks again and best wishes from,
