I had Joe Star* install a boiler (Triangle Tube Prestige Solo-110) a few years back and now I can't seem to reach him and I'm stuck. System was mostly without issue until last year when we had it serviced (by other). After the service, we got this same error message maybe once per month. It disappeared for the warm weather so it's somehow related to heating. Now that its heating season, its back and its daily or multiple times a day.
Had someone come look at it and he wants to replace the ignitor and flame sensor for $. I can't see why that would be the issue being that it fires up easily after hitting the reset? Unsure what the "external trigger" may be or if its something I can address myself.
Anyone recommend someone versed in Triange Tube boilers in the central jersey area? Thanks!
