Burner indicator keeps switching off.

Hi,
I have a britony combi boiler and need a bit of help!

When i turn my heating & hot water on the burner light comes on then after about 10 secs turns itself off. This then prevents any hot water and heating.

Any advice would be much appreciated.

Thankyou

Is there continuous ignition ? may just be the flame sensing electrode is not sensing the flame, could be a faulty electrode or could be a break in the HT lead.
