Jura Z 5 Model drain valve solenoid replacement

简介

Removing and replacing the solenoid for the drain valve is quite simple. If the drain valve is not opened properly, the most likely failure pattern is as follows: after rinsing, the pressure is not taken from the brew group, the brew group motor continues to try to work, sounds very agonized. This process repeats itself a few times.

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!!!!

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!

步骤 10

In newer models, there is a drainage motor instead of a magnet. In principle, it is removed in the same way as the magnet. Use these instructions
Remove the two Torx T15 screws on the drain motor and take out the motor. The side with the blue cable is marked with a dot.
If you have only removed the motor to make further repairs, you can proceed to the next step.
First leave the motor connected. Trigger a flush and observe if the pin moves back and forth.
The motor does not necessarily need to be replaced. Bend away the four metal tabs on the motor flange and detach the metal housing from the black gear case. Now you can try to turn the armature. The pin should move smoothly back and forth. If not, some silicone grease on the drive worm can help.
