So, since I've never had to do any repairs on this machine, I really don't know a whole lot about it. Recently the water temp has taken a dump. The first thing I thought was maybe the thermostat might need to be replaced, but I'm wondering if there are any other things that would cause the machine not to produce hot water. The diverter is ALWAYS open and the radiator cap is barely warm. Any thoughts?
