Wires were unplugs to remove part to be serviced, when putting wires back, they wrote something wrong, the boiler works fine, there's heat coming fine, however, it keeps on building pressure until the emergency pressure valve goes off. Somehow the wires were connected wrong and they can't figure out hoe it goes, they won't try switching around because they can cause a lot of damage by connecting the wrong wires. Can someone help, Do you know where the wires go? Any help would be appreciated Thanks.
