Melitta Cafeo E 930-103 brewing unit

After I cleaned the expansion vessel and
changed the drainage valve
in my Melitta fully automatic machine,
the machine does not recognize the installed brewing group


. In the display is still the message "Install brew group" Where can the error be? For help I would be grateful. Greetings BerndAll

Check all cables.
The brew group is detected via the switch in the picture.

It recognizes the brew group again. But I have another problem. After cleaning I suddenly had a small white 2 pin female connector too much. The cables on it are red and gray( maybe black too ) .One cable goes to the connector attached to the outside of the drive box .The second Kaqbel goes to the micro switch at the bottom of the drip tray., Can you tell me where I need to put this culprit. Greetings Bernd

What kind of machine exactly are you talking about? I do not know an E930 -103.
The plug should actually be on the circuit board.

My fully automatic machine has the type
Meltta, E 970-103
.

This problem has been solved . The plug-in point " Mot-Be " was the correct plug-in point for my remaining socket. I would like to thank everyone who tried to help me. Merry Christmas and a Happy New Year Stay healthy Greeting Bernd
