I have recently installed the above machine in a café, the machine has had extensive use today.
I was called back to the machine, the grinders will no longer activate, but the machine goes through a full espresso cycle and of course only delivers water.
The questions are... 1) is the thermal overload protection on the grinder motors, 2) is there fuse protection on the grinder motor supply , 3) I have most of the information on the machine but would appreciate a schematic diagram if anyone has one available, I ask this because the regular coffee grinder motor is very hot and could have suffered insulation failure.
