Morning.
Either you've got a problem with the flow of gas and there's no gas to ignite and hence no flame for the ionisation probe to detect or the probe is faulty and is not detecting the flame properly and has shut your system down. Chances are your gas supply is ok (you have paid your bill ?) and it's the probe at fault. Sometimes the system has a hiccup so try turning the whole boiler off and waiting a while and then turn it back on and see if the same fault returns or is cleared.

It really helps to give make and model of boiler.
Don't know if it's one which has a glass viewing window which enables you to see the burner, but if so, observe carefully what happens when it tries to start up, and where in the sequence it fails.
Another cause of this failure on some boilers is the live and neutral connected wrong way around. Has anyone done any electrical work on the boiler supply just recently?
