Miele CM6350 continuous loop decalcifying

Hello dear people,

having the following problem with my approx. 2 year old Miele fully automatic coffee maker (model CM 6350):

The machine wanted to be decalcified-so it stood around for approx. 2 weeks because nobody was at home.
The first time decalcifying went perfectly.
After 5 cups of coffee, however, the coffee flowed out of a high pressure outlet valve only. So I thought I'd repeat the whole cleaning process.
When descaling, the error message "Empty drip tray and grounds container" was displayed at minute 6, although nothing was inside.
I emptied the drip tray and grounds container again and the machine started the descaling process all over again.
(Fill water tank with decalcifier up to the mark... Descaler dissolves in ....0.12h...at minute 6 a short rinse, then again the same..."empty drip tray and grounds container".... )
I have now played along with the game about 100 times - Miele won't let you abort the decalcification process I also cleaned and dried everything I could without disassembling anything.

We have the sane problem with my machine miele 5200 and iam sick of it i don’t know how to abort it ?

Hi we had the same problem... my wife had to repeat the process and when I did it for the third time! I added hot water with the tablet in and then it complete the prosess and was good.
Conclusion: Don't use cold water with the tablet in.

Another nice Miele variant for despair. But ours is a VCA 6401 and this one suggests the following: Descale the unit. Great, understandably without care no coffee. Let's go only this care takes this time no end. So, empty the drip tray; fill the water tank with descaling agent and lukewarm water up to the descaling mark ~ and insert. Now: Insert brewing unit. That's in. How is it supposed to work at all, if the water tank is already inside and the brewing unit is of course already inside. Didn't I have only one or two missing from the beginning? And if there had actually been another one, it certainly wouldn't have fit in there as well. Or have I missed something and am in the wrong film. Seems like a number for stupid. Countless times trying to get out of the dilemma. A pointless exercise. Well then, it's tea time. By the way, there's no such error message in any manual. A call for help from Miele revealed: "We don't know this. Service technician comes, if no Corona with us is present. Mille grazie

Descaling in a loop, 5 times in a row and I don't know how to do it

Hello everyone, I have the following problem with my approx. 2 year old Miele coffee machine (model CM 6350): The machine wanted to be descaled-so unfortunately it stood around for about 2 weeks because nobody was at home. The first time descaling went perfectly. After 5 cups of coffee, however, the coffee only flowed out of one outlet valve at high pressure. So I thought I'd repeat the whole cleaning process again. During descaling, the error message "Empty drip tray and grounds container" appeared at minute 6, although there was nothing inside. I "emptied" them, reinserted them and the machine started the descaling process all over again. (Fill the water tank with descaling agent up to the mark... Descaler dissolves in ....0,12h...at minute 6 a short rinse, then the same thing again... "Empty drip tray and grounds container".... ) I've played this game about 100 times now - Miele won't allow me to cancel the descaling process I've also cleaned and dried everything I can without dismantling anything. Do you have any tips for me on what I could do? I would be grateful for any information! Best regards, Corinna

Perform the reset:
To access this menu, with the machine switched off:
- Press and hold the menu button with the 3 dashes
- Briefly tap the on/off button
- Now press the menu button with the 3 dashes 5 times and hold it down for the 5th time until the reset menu appears.
- Select 'Customer service'
- Select 'Restart'
You can then descale

We have the reasonable problem with my machine miele 5200 and I'm tired I don't know how to cancel it?

miele CM 6560 coffee machine what kind of descaling tablets? are the 6x50g rivtig

Hello, It is absolutely necessary to fill the water tank to the precise low level SS. Remove the tank and look down the side for the SS sign. Otherwise, the descaling process will start all over again.
Good luck and good day to you

Hi, you definitely need to fill the water tank to the exact low water level SS. Take the tank out and look at the bottom of the page for the sign SS. Otherwise the descaling will start all over again endlessly. Good luck and have a nice day

Thanks for the helpful reply! I had just descaled ten times in a row and then read your reply. That was my mistake. The water tank was too full. I filled it exactly to the SS limit and now everything worked. Thank you thank you thank you!

Reinigen Sie die Kontakte aus Metal die sich am Abtropfschale befinden, mit einem Tropfen Handspülmittel unter fließend warmem Wasser.

Reinigen Sie auch den Zwischenraum zwischen den Kontakten gründlich mit etwas Handspülmittel, einer Bürste (z. B. Zahnbürste) und warmem Wasser.

Drehen Sie die Abtropfschale um.

Reinigen Sie die Kontakte auch von unten gründlich.

Trocknen Sie die Kontakte und den Zwischenraum zwischen den Kontakten gut ab.

Trocknen Sie die Abtropfschale. Manchmal muss man die Kontakte 2x reinigen

Ich hatte heute das selbe Problem, nach dreimaligem Entkalken wurde ich stutzig und habe im Internet nach einer Lösung gesucht. In einem anderen Forum wurde ein Reset empfohlen, der aber auch nicht funktioniert hat wie beschrieben.
Geholfen hat mir indirekt hier der obige Post, dass man nur die beschriebene Wassermenge verwenden soll. Ich war mir zwar sicher, dass ich die richtige Menge beim Entkalken verwendet habe, genauso wie in den vielen vielen Malen vorher, wo das Problem auch nicht auftrat. Aber ich dachte mir, lass ich sie mal mit der beschriebenen Menge Wasser nochmal durchlaufen, jedoch diesmal ohne Entkalkungstabletten. Und siehe da, die Maschine verließ die Endlosschleife und beendete den Entkalkungsvorgang.

Vielen Dank, der letzte Tip hat mich und meine CM 6350 aus der Endlosschleife gerettet!
Jetzt kann es wieder exzellenten Espresso geben. Und ab jetzt wird die Anleitung akribisch befolgt, genaue Wassermenge und lauwarmes Wasser….
Toitoitoi!
