I had the same problem. There's another clear rubber pipe underneath, that runs from the front right to a pump in the middle. I had to pull it off and dry it with a hairdryer before mine would light properly. Blast into the hole the pipe came off too to dry the sensor if there is one.

I have a similar problem with this boiler. When CH on, boiler overpressurises, (check relief valve outlet) You will then lose water from the CH loop and will have to repressurise when the CH loop cools. The problem is most likely caused by a loss of air from the expansion tank, which will need re-charged. This is not a big job as it has a standard tyre type valve connection but needs an accurate pressure gauge. Probably best left for plumber.
