My boiler turned off and when I went to check my Beckett GeniSys 7505 was flashing red. I've pushed the button to get the boiler running but so far it's happened at least 3 times in the last week.

Should I call to get it serviced or is there something I can do besides pushing the button to get the boiler to start?

I should say that I'm not very handy with that sort of thing so any advice is welcome...
