I have a POS Versicharge VC30 sitting on my garage floor because it failed: the power available light flashes green, but NOTHING else works (no halo light, no fault light). The car sees that it is plugged in, but displays "unable to charge" (and car charges on other EVSE). Siemens manual does not even list the flashing power available light in the troubleshooting, and Siemens support was WORSE: they asked for photos of the installation, the lights, the J1772 plug, the car's socket, and the dash display. Then they asked for make, year and model of vehicle, and then... radio silence. I complained a week later to their CEO, and the response I finally received was that it was out of warranty. No diagnosis, no parts, no repairs, just buh-bye. Siemens is a huge company, sometimes referred to as the European General Electric, as they make power systems like windmills, as well as medical equipment like MRIs and CT scanners. SHOCKING that there is no customer service whatsoever
