Good morning,
I purchased a Siemens EQ 8 Series 900. It was described with a defective grinder.
I was able to find and fix the problem relatively quickly. Now I have the problem that it grinds for 2-3s and then just stops, but without an error message. In the service menu, the grinder turns on for 5s and grinds beautifully. "Grinder has been replaced with a working one."
What I noticed, however, As soon as I want to turn off the machine, the machine flushes and starts up again immediately. However, the icons of the selection are then gone, these only appear again when I want to select another coffee. Now could it really be that the control board has a quirk?
Oh yes... The problem of the grinder was the circuit board. There were 2 transistors burned, which are responsible for the grinder, so my guess is that more is defective on the board.
