I got mine from Galaxus with a CH plug (T13).

I bought the machine in Switzerland and also use it in Switzerland. As noted by Aschiperr78, I received it with the Swiss plug (T13), which is perfect for me. Probably true for the majority of buyers in Switzerland.
If you absolutely need a Suko plug, cut off the CH plug and install a Schuko F, or use an adapter.

Hello Michael
I am an end user. You have to address your technical question to Siemens.
Good luck and greetings
