Αντιγράφω κι εδώ από ξένο φόρουμ που το πόσταρα (οπότε και συμπαθάτε τα αγγλικά) για επισκευή Melitta που εμφανίζει System Error 14:
I had this error after the machine hadn't been used for about 30 days. Internet knowledge seemed to indicate that this relates to the bean select/grinder mechanism and suggested a cleanout should sort it out. I vacuumed everything out but the error was still there. At that point I decided to bite the bullet and tear the machine up.
This happened in the morning before I had my first dose of coffee, so I had to take my old Mokka pot out (which doesn't work on induction hobs, as I found out):
After I disassembled it (took a bit of time as there is a hidden screw that is not immediately evident), I got to the hopper and grinder system. I cleaned everything out again but the error was still present.
I then removed loads of bits, connectors etc to get the bean select system completely out and I reckoned it was the actual motor/gears/shaft that had jammed, which was not easily accessible. Removed the motor assembly cover off (a few clips around its case), applied power to the motor directly and it wouldn't move. Pulled the motor out, applied power and it moved freely. I then moved the gear mechanism by hand, reinstalled the motor and powered it up again; it now moved without an issue.
Buttoned the machine up and it powered-up without an error.
Hope this helps someone.

Follow this guide to get the basic panels off:

What you see once you take the top panel off:
Location of clips on top panel so you can target them individually (I used a trim toolkit for these)
To take the left side panel out (the one with the on/off switch) you need to unplug this connector from a circuit board that's mounted on it (along with a water pipe, but that's obvious):
