Problem with setting up the payment system for Miele Washing Machine

[pepolavigo]

Hello!
We are facing some problems while setting up the centralized payment system with some of Miele machines.

The particular model is PW6065.

We 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

We 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!
