My Baxi Combi HE 133 Plus boiler (3/4 yrs old) keeps showing the dry fire fault lights. A registered engineer has looked at it and can't find any problems, and if I reset the system it ticks over ok for a few weeks before showing the fault again. One of our radiators needs bleeding a lot (almost every 1/2 weeks) - but I'm not sure if these two things are connected. Any thoughts?

If you have to re pressure the system every two weeks it's not good for the boiler
There is a water leak on the system
