| + | [* black] The first thing to check is the PRESSURE gauge. Quite often there is a marker (the RED needle). This tells you the pressure the system normally sits at. A little more or less is not a problem, but the one here reads (the black needle) ZERO. That means the system has lost its pressure so can no longer work. Time to call in someone to maintain it. |
