Hello, I recently gave my Jura E75 a deep clean. In the process, I have disassembled the brew group as specified and reassembled as specified. Of course, I have renewed all zero rings and provided with S-grease. At the first start, the drive made an untypical noise, a few seconds later it banged in the trester bowl and at the same time the same was pushed forward about 3cm from its home position. At the last moment the display showed fault 8. What did I not pay attention to?
Thanks
