Recently, my Gaggia Platinum Vision seems to have given up the ghost. The machine will not make coffee, or even advance to the main menu. Upon cycling the power, I can hear a couple of clicking / clunking noises (which are louder if I turn the steam knob on), then the message "dispensing failed" flashes on the screen, followed by the wrench and "restart to solve problem" message. Restarting does nothing but repeat that cycle. Also, I get this message whether I have the brew group inserted, or not (trying to troubleshoot). I have maintained the machine per instructions, have lubricated the brew group and checked for free movement, cleaned the grinder, brew head, and descaled within a couple weeks. The machine seemed to be working fine until this problem occurred. Any chance this is user serviceable? I love fixing things myself.
