My old Machine has started making very weak coffee...
I have had my machine since aprox. jan 2007, and it has been making very weak espresso for about six months now. I have taken the screen out and cleaned it, as well as run vinegar through it multiple times. The vinegar stopped the steamer from leaking but the coffee is still weak. I do not think that it comes out as hot as it used to either. Although i do not have a thermometer, this is leading me to believe that the burner has gone bad... the lights still come on like normal and the steamer works great.
