I agree with the previous writer: It can only make coffee, but very well. I already own the second machine. And in the meantime I repair the thing myself (change seals, replace general wear and tear). There are great descriptions at https://www.komtra.de and also the necessary, mega-cheap spare parts.
Conclusion: a super coffee machine that simply does what you bought it for. It makes great coffee. I can only recommend it. Because compare the price. Top.
Best regards

No. That's what kettles are for.

No, you can't, but the coffee is good.
