Lochinvar KBN150 not turning on.

thewireman Member Posts: 6
Hi guys.

I have the Lochinvar KBN150 boiler and it was running just fine for a couple of days when I installed it until I had to shut it down to tighten the fittings due the water leaks. As I tighten the fittings and tried to turn it back on, the screen will light up but no display. It would also make the clicking noise, coming from the control board. Does anybody know what's going on?
