If you're experiencing these symptoms, then you need to refresh your Miele CM7 brew unit:
- coffee is cold and doesn't taste good (too light)
- water in waste container
- no water coming out of distribution while rinsing
It's easy, and much cheaper than a brand-new brewing unit!

T15 bit must be at least 1.7 inch (4.4 cm) long, and at most 0.3 inch (0.75 cm) thick. T10 bit can be any size.
-
Blower and sharpy (on left) are must-have for cleaning the filters.
-
-
-
This is the kit I used. It comes with 3 O-Rings, and some grease.
-
Note: the sharp plastic tool is not provided with the kit, I used it to remove old O-Rings.

-
Push the axle to the right.
-
While maintaining the axle (there is a spring), push the release tab on the handle.
-
Rotate the handle to the bottom of the brewing unit.
-
Release the axle, remove the screw (T10) for the handle.
-
Slide the handle to get it free.
-
-
-
Remove 7 * T15 screws, all the same.

Pull the upper body upward.

You are now with 8 screws: 1T10 (at left) for the handle, 7 T15 for the body.

-
-
Remove the upper cover and the spring-loaded axle (both may fall when opening the brewing unit).
-
Rotate the brewer to face the upper filter, then pull it (you may need to negotiate with the elbowed pipe).
-
-
-
Unscrew the elbow part, remove it, change the O-Ring on the smaller part (the other O-Ring never move and shouldn't need a change!).
-
Using a robust, thin tool, apply pressure to extract the axle. It may pop up, please be ready for it.
-
Extract the lower filter.
-
-
-
Cleanup the brewer body, taking good care at the hole at the bottom.
-
Using a torchlight, you can check that it is clean.
-
Insert the tip of the axle lever in the filter rod, then push the axle back in place. Note: the emptied parts of the lever are to go to the bottom.
-
-
-
Unscrew the filter, T10 Torx.
-
Also remove the plastic retaining part.
-
Cleanup the upper filter (same method as for the bottom one), change the O-Ring.
-
Ensure that the spring-loaded valve is moving freely (tip: you can gently use your T10 bit).
-
Put back the plastic retaining part and filter in place. Note: the emptied side of the retaining part is to go on the O-Ring side.
-
-
-
Change the little O-Ring on the side of the brewing unit.
-
Put the brewer back in place, in line with the top part.
-
-
-
Insert the top cover, ensuring that the tab will go in its place.
-
Rotate the brewer clockwise, then rotate the upper axle counter-clockwise to hang up with the brewer.
-
Insert the bottom spring-loaded axle, make sure you insert it the right way round.
-
-
-
Check the upper cover. It is OK to have the 2 little tips visible.
-
Reinsert the handle, slide it on the axle, fasten the screw. Then rotate it back to original position (then, it shouldn't be able to rotate back).
-
Enjoy your coffee!
