CR 757 - brewing group can no longer be used

Hello,

I have unfortunately taken problems with my Nivona CafeRomatica 757.

Gestern evening broth group to clean. Machine was off.
She went out heavy somehow. So I had to shake a bit after turning the lever.

Today it can't be used properly anymore. It's kind of hard, and she doesn't lock up right. The lever cannot be moved non-violently.

The lower part of the brewing group can be moved manually without any problems.
In my opinion, the position in the machine also seems to be correct, I do not see the problem.

Abide pictures about the position of the brewing group.

The only thing I noticed was the upper metal lever on the brewing group, which is supposed to actuate the left upper shifting in the machine, at the bottom.
To operate the switch it would have to be up, no idea how it normally works when used :/
But the lever cannot be moved (what exactly does this upper part of the brewing group do?)

I have already pressed the two switches manually and let the machine switch on (so that it moves to the home position, if that would be the problem).
For the machine everything is okay, but the problem doesn't change.

That can't be that the brewing group just won't go in anymore....

Request help, need Coffee

Hello Oliver,

have come across your thread because I have the same problem. Could you solve the problem back then?

Just in case someone still has this problem:
The next day the brewing unit suddenly went to push in a little further (for whatever reason). With quite a lot of pressure it was even possible to turn the locking lever and the machine runs again...

Das Problem hatte ich auch und habe nun nach langem suchen eine ganz einfache Lösung gefunden.
Durch das intensive Reinigen der Maschine ist lediglich das Gummi im Führungszapfen ausgetrocknet.
Macht man hier einfach etwas Siliconfett drauf, funktioniert das einsetzen der der Brüheinheit wieder einwandfrei.

Thank you very much for the tip with silicone grease! for
one hour I almost
took
my life at the brewing group
now I

smeared it and everything

was fine. A

thousand

thanks

I haven't had coffee in hours. The grease thing saved our weekend.
Thank you very much.

..You may oil the cone otherwise also gladly with salad oil times a little bit if nothing else to the hand...

Wow! After an hour of desperation and 1000 trying to get her brew group back in, I followed this tip here and poof!!! Thanks

that's exactly how I did it->
used cooking oil - and .... immediately ready for use again

Also thank you very much for this simple and ingenious tip, a little bit of fat on it and you'll be fine again

Thanks for the great tip.
I was beginning to think this weekend was over.

Salad oil on it, then gings. Thank you for this tip.

Hi friends a great tip!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
