Introduction

If the coffee doesn´t flow right into your cup, but in the drawer the drainage valve might be broken. You can replace the gaskets in the valve or simply the whole valve.

These instructions may also help with other Siemens/Bosch models and with coffee makers from Nivona, Melitta, and Miele—they have a very similar design.

Tools

Parts

Drainage Valve

Step 1

Unplug your coffee maker!
Remove the water container, the brew group and the drip tray with pomace container.
Using a spoon, remove as much of the coffee beans as possible from the coffee bean container.
Depending on the model, additional sensors with cables may be installed on the top and side panels. You have to remove these before you can completely remove the housing parts.

Step 2

Remove the two Torx T10 screws on the top.

Step 3

Remove seven T10 Torx screws on the back.
The two screws at the bottom of the front can remain.

Step 4

Press with a flat-head screwdriver into the openings on the side with the water tank. This releases the latches on the top.
Press the flat-head screwdriver into the opening on the side with the brew group. This will release the last notch on the top.
Lift the top off.
On some models, a cable leads to the sensor on the powder tray. Unplug the connector on this cable first.

Step 5

Slide the side section of the brewing unit about 2 cm to the rear. This sometimes gets stuck and may require some force to remove.
Remove the two tabs from the power switch.
Take off the side panel with the brew group.

Step 6

Do the same with the panel on the other side.
To remove the water tank hose simply pull it of the pump.
Remove the side panel.

Hallo, das ja ganz tolĺ erklärt. Ich brauchte ein Bild von dem Elektronicteil wo man die Kabel sieht in welcher Buchsen Sie stecken.Danke.

Bei den anderen Anleitungen vielleicht, z.B. der hier: Siemens Surpresso Compact microswitches in the gear drive replacement, Schritt 10 ?

Step 7

Rotate clockwise the expansion box about 60 degrees and pull it out.
The expansion box is frequently filled with coffee oils or grounds. Clean it from time to time. It can easily be separated into two halves.

Step 8

The drainage valve is directly plugged to the gear drive. The drive is fixed with five Torx T10 screws on the center panel behind the brew group.
Remove the five Torx T10 screws holding the gear drive in place.

Step 9

Push the gear drive outwards to the left. Pay attention, several cables might get caught.
Lay the gear drive on its side. Loosen the upper water connector by pulling the clamp and than sliding off the hose. Mind the O-ring on the end of the hose, replace it if necessary.

Step 10

The drainage valve is exposed.
Remove the spring on the lower end of the valve.
Lift the upper gray part of the valve. Push the lower part of the valve a little bit downwards und lift it out.

Conclusion

To reassemble your device, follow the steps in reverse order.

Hi, will be a issue if i will cancel the valve by removing the cam and setting up the position as water will go straight away to brew?

Do I understand it right: you want to use the surpresso without a drainage valve? I think it's impossible. Swap it, it's rather cheap.

Hat sehr gut geklappt! Hatte kurz Streit mit der Brühgruppe, aber ich habe dann gewonnen. Danke, sehr hilfreiche Anleitung. Manchmal muss man sich bloß trauen...

Coffee machine did not make coffee, I heard that there was some valve that had trouble opening. I first replaced the 'other' valve; that did not help. After replacing this valve, the coffee machine is back up for a week now.

Thanks!
