Dunkirk boilers

Options
I have a Dunkirk D247 hot water boiler. It started firing up for a couple minutes then would shut off for 45 seconds and then fire up again. I turned off the power and when I turned it back on minutes later the electronic spark kept sparking , the pilot was lit but low flame and the boiler would not fire up. Any suggestions would be appreciated

    First guess would be to clean pilot burner and also clean flame sensor. BTW, don't lose the orifice out of the pilot burner.
