Potterton puma 80e - no pilot light?

Boiler been working fine until Sunday night, Ran a bath as normal but then also tried to fill the sink but no hot water or central heating.
Mains light lit but boiler wont fire, No pilot light.
There is a red led illuminated on the control board when hot tap is on and you can also hear the clicking of a switch when hot tap used but no pressure or hot water.
Any ideas please
