At the beginning you have to only a few cups make coffee (about 2-3 times) which are then thrown out, but of course I have taken cheap coffee. One has to enter the pot, so to speak first. But then you have a long and really a lot of it.
Cleaning I carry out only with hot water, not for the dishwasher. The water tank is running after some time inside, but also that is perfectly normal and does not detract from the taste.
After non-use (eg vacation period), you should screw together before, put a tea bag with coarse salt in the dry water tank, it pulls some moisture gradually sweats anyway. The salt absorbs moisture and there is no unpleasant odor. Also one must sometimes pull a long time, the screw in the cover and to exchange the seal. (The seal when used daily, about every 4 months. Power mostly by noticeable that water when cooking emerges from the middle and evaporated.)
When you have filled in too much water, then do not scare that valve lets the steam then very loud from, but nothing else happens. Always so much water, fill to just below the valve indoors, then this does not happen. I have forgotten to fill before water and put the stove and wondered that nothing rattles it (the morning) because the gasket was blown and I had to replace the, after that everything was back to normal.
I have several versions of Bialetti and the purchase is worth all the time (and Bialetti is better than other machines of the same type by far).
