I've had my Combi 199 boiler working fine until about a year ago when it started giving me error 10 once and a while. Sometime it happens once a day and sometime once a week or even 2 weeks. I have replaced main board, the igniter, cleaned the burner, replaced the flame detector and made sure there was no blockage on the vents. Even after all that I keep getting error 10.

    Well since you replaced all the parts I'm going to direct you towards the gas supply, as in the gas coming into the boiler. You need to record incoming gas pressure at the appliance, and also check it with everything else that uses gas turned on. Other than that maybe you have a loose wire, but i would start with the gas since it costs no money to fully check that out.

    What the manual say about the E10 code and how to diagnose the problem?
