Position the machine with the water tank side facing you.
The panel covering the brew group is fixed at the top edge with two oval head screws.
These screws have an oval head and look like rivets. They require a special tool or bit for unscrewing. Here is a DIY guide . In a pinch you can also use needle nosed pliers. Jura wants to keep us out of our own machines!
Remove the two oval head screws and lift the panel out.
There it is: the brewing unit.

One Torx T15 screw
The hot water inlet is plugged in.
