Baxi 105e - Central heating not running continuously

[Jmar2971]

Currently have an issue with my Baxi 105e combi boiler, the hot water is working fine so no issue there and on the first fire up and heating of the water for central heating there is no issue.

The issue that I have is once the CH has been on for around 10 minutes the ignition stops and then every now and again the boiler will fire up and a couple of seconds later stop again, the radiators are then cold. The green light stays on for the CH and you can hear everything running but no ignition and as so no heat. Thermostat is set to around 21 degrees but the ignition is never on long enough to even get past 16-17 degrees.

I have an engineer coming out next Thursday but wanted to know if anyone had a similar issue before?

Thanks.
