Remove the Jura sign.

Step 3

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!!!!

Step 5

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.

Step 6

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

Step 7

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!

Step 9

              Water Heater

Here is one of the two water heaters removed.
A resistance measurement gives an indication of whether the heater is defective. Pull off one of the spade connectors. If the resistance is infinity or zero, then everything is clear… it should be in the 40 - 50 ohm range. But there could also be a short circuit from the heater to the metal housing, here the resistance must actually be infinite.
To check whether the heater is limed, you have to detach the two pressure hoses and blow into them. That has to go very easy.

Step 12

The two water heaters are fixed in the middle with a Torx T25 screw (marked in red). The locknut on the back is loose in the carrier and often falls out while turning the screw.
Unscrew the screw on the heater to be replaced. Watch the lock nut on the back.
Carefully remove the connectors on the sensor cables. For assembly, remember which sensor is connected to the red wire pair and which to the green wire pair.
Gently remove the water heater. It is still connected by hoses and wires.

Step 13

Remove the cable shoes from the water heater connections.
Remove both Torx T25 screws from the brackets on the thermal fuses. Remove the thermal fuses.
Remove the Torx T25 screw from the eyelet of the yellow / green ground cable. Detach the cable.
The thermosensor may stay. If it is defective (the machine then reports Error 4), it has to be replaced

Step 14

Now only the hoses are connected. They are attached with clips.
The clips are easy to open and close: attach a pair of pliers as shown in the photo and squeeze them together. The clamping plate falls out immediately and releases the clamping ring, which can then be compressed with the pliers and pushed away.
To close the clips, you must first insert the clamping plate and press down firmly with your fingers or pliers. It then snaps in and secures the clamping ring. To understand the principle, look closely at the clips in other places.
When the clips are open, the hose can be pushed off with some force.
