Gorenje W6503 washing machine - how to set a Favorite Program?

Hello, despite the manual, I can't set my favorite program on the Gorenje W6503 Washing Machine.
I am asking for help, because when the knob is turned to Favorite Program, only the word SEL appears and there is nothing you can do about it.
greetings

You set eg Favorite program 1. It is SEL. You turn to the program to be remembered. And confirm by pressing buttons 6a + 7 together. The rest in the manual.

Hello, I have an identical problem. maybe someone will help me.
I am looking for a program in the washing machine gornje w7763i with a duration of about 1 hour and a temperature of 60 degrees. There is no. If there is such a time, the temperature is max. 40 degrees. And if the temperature is 60 degrees, again the time is at least 2 hours. 40 min.
I called the hotline and the lady said that I have to program such a program for 60 minutes and 60 degrees. The question is how?
I switch to my favorite program, the display shows SEL and nothing else can be set. The temperature and time buttons are disabled.

I don't want to program my favorite program from the ones that are available. I want to create my own with time and temperature that suit me. Can anyone help me?
