Step 3

  • The top cover is fastened with oval head screws. Unscrew them.
  • 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!!!

  • Now the grinder is free. Again take a picture, then pull out the axis of the adjuster with moderate force.
  • Depending on the model you will find a silicon sealing on top of the grinder ring, remove it.
  • Watch the fabrication signs , here green. This alignment must be restored later. Now turn the great black gear about 90 degrees counterclockwise. The grinder ring is free and can be lifted off.

              The Grinder Cone
  • In the next step be very careful not to loose these three springs, balls and cartridges.
  • The grinding cone is fastened with a long Torx T20 screw. The screw head is often covered with remnants of coffee beans. Expose the head and turn the screw out counterclockwise.

Step 13

              Cleaning
  • In most of the cases the mill is full of sticky old coffee powder. Clean everything thoroughly for excellent coffee aroma.
  • The felt ring around the drive axis can be pulled out carefully using a needle. Clean it. For the inner grinder use a paint brush and a wet cloth, the other parts can be cleaned with a brush and warm water. Each part must be dried well before reassembling it.

Step 14

              Change The Grinder Ring
  • Push both of the small latches alternately. Then the ring cover should come out.
  • Two clamps hold the grinder ring in its place, push them aside and it should come free.
  • Again clean everything. Press the new ring and cover in its place. With that the grinder ring is exchanged.

Step 15

              Change The Grinder Cone
  • First insert the cleaned driver, then the three sleeves, springs and balls. Now fit the grinding cone on the three balls.
  • Then fit the auger, screw in central screws. When screwing in, push the cone downwards and make sure that everything meshes.
  • This screw turns into plastic. If it doesn’t fit properly, the thread will be damaged. So first turn the screw counterclockwise until you feel that the first thread is engaged. Then tighten it turning clockwise.

Step 16

              Reassembling
  • Insert grinding ring. The black gear is turned to the right again until the three marks are aligned. Then reinstall the adjuster drive shaft as it was originally.
  • The adjustment oft the new grinder burrs musst not necessarily be the same as the old ones. You can approximately find the mean position, which was marked before, by turning the outer ring as far as possible clockwise, then turning it fourteen clicks backwards.
  • It is a good idea to check if the grinder rotates freely. You can remove the meal hopper and look at the millstones from the side.
  • Then install the remaining parts in reverse order.
  • You can set the grinding degree nicely by placing an empty roll of toilet paper perpendicular to the open mill and filling it with a few coffee beans. Plug in the plug (be careful!), choose a cup of coffee and watch as the coffee grounds fall out of the grinder.

              Before - After
  • These two pictures are no fake: Before repairing the grinder the coffee is thin and transparent. With new stones the coffee is strong and has a fine crema. The repair was a real success!
