Absolutely disappointed by Siemens zeolite dishwasher

For some time I hear a loud pounding when flushing, which I initially led to incorrect sorting the dishes back. Now the customer service has determined that a part is defective, which makes the water supply to wobble. Approximately 200 repair, to back the fan, again about 50 microns.

From the outset, I am with the dryer performance very dissatisfied, in the hollows of cups, bowls etc. is the water, the cutlery tray is wet, as was the cutlery. I have to constantly wipe dry everything.
To exploit the Zeolithausrüstung, I was told that I should not open too soon the machine. Now it is, the drying would be better if I open the machine in the first half hour after the end. Right, but where is the Enerergieersparnis?

I have a number of devices from Siemens and am satisfied on the whole. But if I'm going to buy a new dishwasher - then certainly not from Siemens.
