The heater core sprung a tiny pinhole leak and got some components wet. I popped the hood, found the breach, turned off the water and managed to McGiver the leak and put the hood back on after a few days to let it all dry out. At this point it'll fire up intermittently. Sometimes at about half the temperature. It was set @120 degreesF and seems to run @ about half that when it doesn't fully kick in. Is there a trouble shoot/ reboot or something I can do to bring back consistent hot water?
