  9. Behind the Jura sign are two screws with an oval head. They have to be removed.
  10. 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!!!!

  25. Remove the two Phillips screws on the bean container and remove the bean container.
  26. Lift the cover upwards.
  27. If it is stuck, use a plastic opening tool to carefully pry it open.

  33. The drainage motor on the Z6 and following models is fixed with two Torx T15 screws. Unscrew them and pull out the motor.
  34. 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.

  36. The gearbox (the black plastic part) is attached to the metal engine block with four metal tabs. Straighten the tabs with a small screwdriver.
  37. Pull the gearbox off the engine block.

  39. Turn the armature of the motor while holding the pin. Check whether the pin moves back and forth.
  40. This probably solves the blockage. Grease the worm (and the pin) again a little. Position the worm so that it protrudes about 3 mm.
  41. Reassemble the motor and bend the retaining tabs on the metal housing until it is tight.
