Hello,
I bought a broken Melitta Caffeo Bistro and repaired it. I saw 2 buttons on the gearbox for the brew group, which are operated by a cam wheel. And a button that sits at the top of the brew group.
Does anyone happen to know what function the individual switches have or can someone give me a detailed description of the individual functions the buttons have during a brewing process.smile.gif
Thanks in advance.

The top button is used to detect whether the brew group is inserted.

The other 2 detect the upper and lower position of the brew group.

Thank you and what is the switch that is activated when pressure builds up in the brew group?
