Incidentally, the inlet hose shown in the one picture (which looks like the scope of delivery) is also not included. Otherwise it is correct. A Bob Pop Cassette, 10 Bob Tabs and the operating instructions are still included.
Logically, the waste water must go into the drain as it contains washing-up liquid. This is done by means of a hose that can be draped around the sink tap using a device and the end of which is placed in the drain. This is all included in the delivery. Additional hoses and installation options are not included. For further options, I recommend you visit the manufacturer's website, where you can also find operating instructions, for example. -Galaxus supplied me with a CH cable in addition to the EU cable.
