简介

The outlet valve prevents water from flowing back. It is a common source of failure, often becoming leaky or impermeable. Maintenance is quite simple and should be done regularly.

  1. Unplug the power cord!
    • Unplug the power cord!

    • Remove the bean compartment.

    • 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!!!

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

    • Now you can pry up the top cover all around.

    • Remove the top cover. This often requires a little force.

    • Use plastic tools to avoid scratching your device.

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

    • Turn the Jura label a few degrees counterclockwise. If it's hard to do, use a small suction cup.

    • Remove the Jura label.

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

    • Using your finger press the black plastic detent down.

    • Push the ceramic valve upward to the right.

    • If you want to replace the valve, you have to disconnect all cables and hoses. If you are only removing the valve to access other components (outlet valve, heat exchanger), you do not need to disconnect the connections.

  11. The outlet valve ist exposed. The lime traces clearly indicate that this valve is leaking. The valve ist connected on the right side to a raccord and held by a metal clip. On the left side are two connections to hoses.

    • The valve ist connected on the right side to a raccord and held by a metal clip. On the left side are two connections to hoses.

    • Using a pair of sharp tweezers pull out the metal clip.

    • Push the valve to the left. There is an O-ring seal on the connection, do not lose it. If possible, replace it during reassembly. The two hoses can remain connected.

  12. Three clips hold the black cap on top of the valve. Using a flathead screwdriver carefully losen them and lift off the cap. Take out the spring, the valve piston and the seals with the spring plate. Note their position for reassembly. This valve had a broken piston and aged seal. They were replaced, the piston from the repair kit is now made from metal and will never break again.
