Hi, my old moulinex blender (D72 "Turbo blender electronic") is completely dead. No response when I plug it in. My flatmate killed it by letting banana smoothie dribble into the base unit. Any suggestions how to diagnose the fault? Also, would a wiring diagram help and where I can get one? BTW I'm a power systems engineer. So I'll know what you're talking about when you use technical terms. I just haven't been trained to fix light appliances. Thanks for the help.
