      Hello. I'm having problems with the steam function. It isn't getting hot enough to actually generate steam. The gauge only goes about a quarter of the way up. I've kept it on for hours and it doesn't change. Any suggestions?

      Sounds like a defective gauge, heating element, wiring, controller/brain unit, or sensor.  It is best a professional evaluate the machine as guessing which part it is can cost more than an evaluation.
