I am Frank, and new.
I have a S8, model 13180, which is a very old model.
I completely cleaned every part of the grinder, and rebuilt correctly. But "fill beans", of course, full beans in the container.
I also have a F7, JURA, so I swapped them. What happened?
The F7 did not work on S8;
The S8 worked on F7 with burned smoke.
And then, I tested the plugs of the grinders, and the contact pins on PCBs.
F7 is 2V, S8 is 0.5V, the pins are same with plugs.
I was wondering if the voltage were correct? My understanding is the grinder of F7 could not run on S8 because it needed a 2V, but the s8 only provided 0.5V. And the burned smoke, because the grinder of S8 could not cover 2V.
And then, I inspected the PCB of S8 visually, found a cable was completely loose, nearby "LOGIC MASK 4" or "LOGIC MASK 3". I did not know which one it should be, but I tried them one by one, still no working.
I also found the "c8" or "cm4" had two empty holes, what they should be?
I see many topic about the "fill beans" error, but could not find an answer.
Thank you for any help.
