Hi @teukuadam,
The tubes that are at the top on both sides are the ones that conduct the hot water from the hopper to the lower part where the filter holder with the ground coffee is. Those tubes are thin so you have to be careful when cleaning the machine.
I saw the water hose, with that size it might contain 4 liters of water.
Great post and you have a great fetish too 😂
If the container is of several liters. Hehehe it's true about the fetish! 😂
Thanks for stopping by!
