ARGO Electric Boiler Circuit Board

I have an ARGO Electric 2 element boiler. I turned it on yesterday and I get all the lights on, TT, safety switch, circ etc. that tell me its working, after 30 seconds I hear a relay fire but no lights for elements come on. I have jumped the thermostat, tested the RTD sensor and the elements. Everything checks out.
I pulled the board to have a closer look and some of the relay blocks were loose. I re soldered them and swapped one out with one of the unused ones down below to test. Still nothing. What am I missing or am I going to spend $450 on a board?

Its getting cold at night.

Welcome to the forums.

Not really familiar with that unit but if I can find a manual or wiring diagram I may be able to help you. Post the model number of that unit.
