Introduction
If the coffee or steam no longer gets hot, or water drips out the back, one of the heaters could be defective. Often you can also see traces of limescale. A first step is to measure the resistance of the heater, it should be around 50 ohms. The instructions show how you can get it out, either to replace it or reseal it.
What you need
-
-
Lift out the coffee tray
-
Remove the lid sealing the coffee bean container
-
Remove all of the coffee beans you can possibly remove.
-
Pull the adjuster of the coffee bean grinder straight up
-
Remove the four T15 Torx screws
-
-
-
The top cover is now free. Lift ´er up and set ´er aside.
With the Impressa XS 90 there is an additional cover above the grinder that has wires glued to it that prevents you from taking the top completely off.
-
-
-
Remove the knob for the steam valve by simply pulling it off.
-
The front cover is secured with a Torx T15 screw. Remove it.

The backpanel is secured with two proprietary screws with oval head. They seem to be rivets, but in fact are screws. The only purpose is, to keep us out of our own devices. You can remove them using an oval drive bit. (Part of some IFixit tool collections or available at a Jura provider or iFixit). In a pitch try needle nose pliers. Here a DIY guide.
-
Remove the two oval head screws on the lower edge of the backpanel.
-
Lift the panel up.
-
-
-
-
Remove the two Torx T15 screws at the bottom of the side panel.
-
Remove the Torx T15 screw on the front bottom right.
-
Remove the Torx T15 on the right underside of the front access door. Flip the door open a few inches.
-
-
-
Pull out the clamp at the bottom of the black angle piece.
-
Pull out the hose, this may be a little difficult.
-
There is an O-ring seal at the end of the hose. It may be stuck in the contra-angle connector. Remove it and replace it with a new one during reassembly.
-
Check that all connections to the cage are really loose, depending on the model they may be different.
-
-
-
The pressure hoses to the boiler are connected with Legris connectors. The hoses can be very tight. If you can't loosen them, you'll have to cut them off right at the Legris connector. This is not a problem if you replace the thermoblock anyway.
-
First press the tube in firmly so that the seal loosens a little. Move the hose and the outer small ring at the end back and forth a little.
-
To get the hose out of the Legris connector, you need to push the small ring at the end firmly in with pliers and pull the hose out at the same time.
-
Thus, the hose is reconnected to the Legris connector:
-
First shorten it about 4 mm so that the connection point seals well.
-
Insert it into the connector and pull it back again briefly, then it should be tight.
-

Hallo,
Das ausbauen des Thermoblocks ist bei mir nicht das Problem.
Bei mir hat der Heizkörper einen Schluss.
Ohne Erde funktioniert die Heizung aber das kann nicht bleiben.
Wo bekomme ich denn eine neue Heizung her.?
With the Impressa XS 90 there is an additional ground beans funnel that needs to be removed that hides two of the four torx screws
