Steps:

1. Unplug the power cord!
2. Remove the water tank and the drip tray. Remove all coffee beans from the storage container.

3. Flip open the lid of the bean compartment.
4. Unscrew the two slotted screws inside the bean compartment. The screws have a rubber washer and will not come out completely.
5. Remove the bean compartment.

6. The top cover is fastened with oval head screws. Unscrew them.
7. These screws have an oval head that makes them look like rivets (picture 2). You need to use a special bit - also available at iFixit - for their removal. Here a DIY guide. 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!!!

8. Also remove the two oval head screws underneath the ground coffee compartment lid.

9. Now you can pry up the top cover all around.
10. Remove the top cover. This often requires a little force.
11. Use plastic tools to avoid scratching your device.

12. Turn the device with the back facing you.
13. Turn the Jura label a few degrees counterclockwise. If it's hard to do, use a small suction cup.
14. Remove the Jura label.

15. Underneath the label you will find two Torx T15 screws. Remove them.
16. Carefully pull the top of the chrome cover slightly outwards, then push it down and put it aside.

17. Remove the Torx T15 screw on the side panel with the water tank.

18. Pull the right side panel slightly towards the back.
19. Remove the side panel.

20. Pull the left side panel slightly towards the back and remove it.

21. The drainage motor on the J6 and following is fastened with two Torx T15 screws. Unscrew those and pull out the motor.
22. For now leave the cables connected to the motor. Trigger a flush and observe if the pin moves back and forth. If not, the gearbox is blocked. You may get it going again by the following steps

23. The gearbox (the black plastic part) attaches to the metal engine block with four metal tabs. Straighten the tabs with a small screwdriver.
24. Pull the gearbox off the engine block.

25. Turn the armature of the motor while holding the pin. Check whether the pin moves back and forth.
26. This may already have released the blockage. Grease the worm (and the pin) again a little. Position it so that it protrudes about 3 mm.
27. Reassemble the motor and bend the retaining tabs on the metal housing until it is tight.
