Does anyone have a Fisher Paykel Dishdrawer (dd603) main PCB Schematic? I am having a problem with one of the transistors that drive the dispenser solenoids. It keeps melting down! I could probably diagnose the culprit component(s) on the board, and it would be infinitely easier if I had the schematic for the board (and for the other boards in the system (chassic pcb, LCD pcb, main pcb). Does anyone have these? This would probably be an inside job - any F&P engineers out there? Anyone else have this problem? Thanks!

By the way, its the Rohm D1867 npn transistor that keeps melting down and frying the solenoid coils at the same time.

I am suspecting the 24v supply too. Do you know if that is on the same pcb or is it down below on the chassis pcb? The transistor literally burns up and melts down on the board. But it works long enough to fry the solenoid coil (it now measures 0 ohms vs about 70 ohms b4). I did have 2 extra solenoids from replacing the dispenser, but now I'm out of extras. Both the upper and lower boards seem to have solenoid problems, but only the top one burns up... Any more tips would be great. Thanks! matt
