Anyway, the machine is really good and the coffee is delicious.
It's not like that I had no problems. Now a small tip from me.
When the engine buzzing too strong or too much water vapor comes from the capsule compartment or more of water in base as in the cup or milk frother works only with half power or is no longer able to foam the milk or, or, or ... .. then the following makes.
Disconnect the steam / hot water nozzle with small turn to the left.
The white Eumel (the thing to move the hot nozzle) upwards to the bend.
The small black nozzle part on the flat was still attached to the hot water nozzle Unscrew (counter-clockwise). The little now visible seal left as it is.
Sets both parts overnight in a container of K tabs (the tabs for the third teeth, at Rossmann there Tabs, other brand, a whole rolls for ca.1,00-2,50 Eur)
Now descale the machine. After 3x descale with fresh water can pass through. Here again provide the steam / hot water knob in the meantime on steam.
Now take the nozzle parts and freed them from the last dirt with a safety pin. It can be quiet deep incursion into the openings.
Then rinse with clear running water and reassemble.
The machine now runs quieter than after the very first start. The milk is foamed within 3 seconds. No steam from the capsule chamber. You will be amazed.
I hope I could help
