Lochinvar lockout issue

I am a homeowner with a Lochinvar Knight boiler, also used for DHW. It was installed 9 years ago and we haven’t had trouble with it until now. I returned home this past weekend from an extended trip and found the boiler locked out, displaying the message “Lockout 1.” It doesn’t cycle past prepurge. I’ve reset and checked fuses. Is this a blower issue? Ignition? Over my pay grade?

    What model? Have you had it serviced regularly? They really do need annual cleaning or they get real plugged up with combustion byproducts. Just an fyi.

    Model no. WHN111. I have had it serviced quasi-regularly, but I would be lying if I said it was annual. I’ll schedule a service and see what I can do in the meantime about cleaning the vent pipe. Many thanks.

    Did it reset and fire up or fail again right away.
