Introduction

Note: The brewing units for the EQ9 is totally different. These instructions do not cover it.

What you need

Step 1

              Revision of the brewing unit
  • Picture of the brewing unit. The first gasket to be replaced is on the blue water inlet.
  • This seal can be replaced immediately without further disassembly. The gasket is under strain and should be replaced quite often. It slides better when thinly coated with food-grade silicone grease.

Step 2

  • The second seal, which should be replaced more often, is located on the upper piston. In theory, it could also be replaced without further disassembly. Since opening the brewing unit is not difficult, it can be cleaned more thoroughly.

Step 3

  • Remove the cover from the upper piston. Reach under the notches on the left and right, a plastic tool is helpful here, but you can also use your fingers. Remove the cover.
  • Now the upper piston is easily accessible from two sides and can be cleaned quite well.

Step 4

  • Place the brewing unit on the work surface as shown.
  • Unscrew the five Torx T10 screws.

Step 5

  • Lift the upper side plate. The rubber bumper at the top of the piston will probably fall off. It must be pushed back into the top of the pin on the side plate during reassembly, with the smaller bumper facing down.

Step 6

  • Pull out the piston completely.
  • Unscrew the Torx T10 screw on the brewing filter.
  • Take off the brewing filter.

Take off the brewing filter.

Step 7

  • Using a blunt tool, lift out the lid above the crema valve. Lift off the lid.
  • The lid is stuck very tightly. Pry it up all around with the tool to lift it up gradually.
  • Pull out the crema valve.

Pull out the crema valve.

Step 8

  • Lift out the cylinder with the lower piston.
  • Now the two Torx T10 screws on the blue water outlet can be removed and the water inlet can be cleaned. It is not absolutely necessary.
  • Now the brewing unit is largely disassembled. The lower piston can also be removed, but it is usually sufficient to thoroughly clean the parts that have now been removed. Replace the O-ring on the upper piston and on the water inlet (possibly on both ends), grease them and the cylinder thinly with food-grade silicone grease.
  • Reassemble everything.

Work through the steps in reverse order to reassemble your device.

von welcher Siemens EQ ist diese, meine der EQ9 sieht ganz anders aus….

Gibt es hier schon jemand, der sich mit meiner Brühgruppe auseinandergesetzt hat?

Grund: Sie macht gerne Schwierigkeiten: BRÜHGRUPPE REINIGEN, obwohl sie sauber ist . Nach Fetten geht sie wieder eine Weile…. In anderen Foren liest man etwas davon, daß an irgendwo einen Gummi (incl. Kerbung) einspannen soll, der dann ein Teil, das klemmt und die Meldung verursacht, in die Richtige Position bringt….

VauWeh - Nov 23, 2020

Stimmt! Die Brühgruppe der EQ.9 ist eine Neuentwicklung und ganz anders. Aber die Maschine dürfte noch so neu sein, dass Garantie drauf ist?

Hallo, VauWeh - leider nein, ist schon 1,5 Jahre über Garantie.

In der Garantie-Zeit ging mir die Brühgruppe insofern kaputt, daß der Druckschlauch durch Abknicken und Überdruck gerissen ist.

(Leider bekomme ich diesen Schlauch nirgends, schade um die fast neue Brühgruppe)

Die Reklamation hat zu einem sofortigen Neuversand geführt, aber genau diese bringt den Fehler “Brühgruppe reinigen”, selbst wenn sie sauber gereinigt und gefettet wieder eingebaut wurde. Nun habe ich gerade Ruhe, nachdem ich sogar die Spindel mit Silikon-Öl besprüht habe.

Danke für die Info. Die EQ9 kenne ich (noch) nicht. Habe mal gegoogelt, das Problem scheint ja häufiger aufzutreten. Hmmm, das Gerät ist doch ganz schön teuer…

so, mittlerweile ist die 2. BE blockiert, die 3. hat einen Riss (während der Reinigung mit Tablette -vllt. weil diese “hochkant” hineinfiel???- Hast du %&^*, die gerissene zu zerlegen, um Sie kennen zu lernen und dabei gleich das Gehäuse der Ersten, wo der Schlauch geplatzt war, zu tauschen? Weiteres per PN?
