Centralized payment wiring for Miele Washing Machine

[pepoLavigo]

Hello! this is my first post in this amazing forum.
I'm facing some problems while setting up the centralized payment system with some these Miele machines.

The particular model is PW6065.

I understand that there is a connector with 7 poles. The first two (1 & 2) are used to set start permitted.
Number 6 should be earth ground

I have the following doubts:

1) In which pin can we read the occupation information, and how?

2) Does the machine provide the voltage supply for the connection of pin 1 and 2 during the start permitted configuration?

Thanks a lot!
Best regards,
Pedro.
