Steps:
- Unplug the machine from the power outlet
- Remove all attachments: water tank, drip tray, aroma lid
- Turn the machine so the back is facing toward the front.
- The Jura sign must be removed. Turn it a few millimeters counterclickwise.
- If this becomes difficult use a suction cup to assist.
- Remove the Jura sign.
- Behind the Jura sign are two screws with an oval head. They have to be removed.
- These screws have an oval head that makes them look like rivets (picture 2). You need to use a special bit for their removal. If the right bit is not available, it could be done with a pair of needle nose pliers. Jura wants to keep us out of our own machines!!!!
- Push the back down a bit and then remove it.
- Pull the right side panel- as seen looking to the frontpanel - backwards and take it off.
- Sometimes it gets a bit stuck and may require a bit more of a pull.
- In this step, you should remove the screws of the left side panel. The side panel can only be removed after removing the top cover.
- Remove the Torx T15 screw on the front wall of the side panel.
- In the side part there is a lid over the brew group. The lid is fastened at the top with two oval head screws. Remove those to remove the lid.
- With the cover removed the brew group becomes visible
- This step shows how to remove the top cover
- Remove the powder tray and all coffee beans.
- The cover is fastened with three Torx T15 screws. Those are easily visible under the covers as well as the small cover on the left back side.
- Remove the two Phillips screws on the bean container and remove the bean container.
- Lift the cover upwards.
- If it is stuck, use a plastic opening tool to carefully pry it open.
- The lid of the bean container is held in place by a small, strong magnet that loosely rests. It is either in the green marked recess, or it remains hanging on the bean container. Make sure it is not lost!
- Pull the left side panel backwards to take it off.
- For some repairs it is not necessary to remove the left side panel.
- The drainage motor on the Z6 and following models is fixed with two Torx T15 screws. Unscrew them and pull out the motor.
- Leave the cables connected to the motor for the time being. Trigger a flushing process and observe whether the pin moves back and forth. If not, the gearbox is blocked. You may be able to get it going with the following steps.
- The gearbox (the black plastic part) is attached to the metal engine block with four metal tabs. Straighten the tabs with a small screwdriver.
- Pull the gearbox off the engine block.
- Turn the armature of the motor while holding the pin. Check whether the pin moves back and forth.
- This probably solves the blockage. Grease the worm (and the pin) again a little. Position the worm so that it protrudes about 3 mm.
- Reassemble the motor and bend the retaining tabs on the metal housing until it is tight.
