What does Jura Professional Service cover is not fitted mean?
A cover on the back of the machine closes off the service area, and the machine checks that it is in place before it runs. If it is missing or not seated, the machine shows Service cover is not fitted and blocks product preparation. The manual's action is to fit the service cover. It is a protective prompt, because the area behind the cover contains parts that should not be reachable while the machine is running. The message typically appears after cleaning or moving the machine, when the cover was taken off and put back without clicking in. If the cover is on and the prompt remains, the cover may be slightly misaligned or the detection switch dirty or damaged. The wording applies to the GIGA X8. Because the check happens before every product, even a cover that is slightly loose can bring the message back after it has cleared once.
