Introduction

Jura Z models have two outlet valves. These valves must be checked more often. The valve plunger often breaks off and the plunger then gets stuck. The seals age over time. A remedy is a new plunger, preferably made of metal.

    • 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!!!!

    Hi there - really trying to find the tool to use for this. Please advise. Is there a link to it that I can buy?

    • 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 Schritt „5“ fehlt der Hinweis auf die noch zu entfernende Schraube unten am vorderen Teil der Seitenwand.

    • 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.

    • Pull out the clamp on the lower outlet valve.

    • Carefully slide the lower outlet valve to the left so that the pressure hose comes out. Watch out for the O-ring. It will either get stuck in the valve or on the end of the hose. Replace it with a new one when reassembling.

    • Lift out the valve. The two hoses on the left can stay on.

    • The cover on top of the valve is held by three detents. Gently release the three detents with the flat end of a spatula and lift the cover straight up.

    • Carefully lift out the spring and valve stem. Pay attention to the sequence for later reassembly.

    • Open the cover on the upper outlet valve in the same way.

    • Gently lift out the valve plunger.

    • Both valve plungers on this unit were broken. They were replaced with new ones. The plastic model is shown here, but a metal valve plunger will never break again.

    • If the plunger is still good, all you need to do is install new gaskets. Coat the seals thinly with food-grade silicone grease.

Conclusion

Work through the steps in reverse order to reassemble your device.
