I had previously been a similar device from Siemens, using the same wash programs which has kept 9.5 years. This new device is quiet and consumes 10 liters of water considerably less than my predecessor device. The average duration of the program in the program "Auto", however, needs 2 hours and 40 min. Approx 20 min. Longer than my old machine (you can not outwit physics halt, less water means longer duration). But the total energy demand is lower than in my old device despite longer duration. In addition, there is a nice add-on program button "VarioSpeed" with the programs "intensive", "car" and "Eco" the term can be halved ("... is obtained by increased energy consumption at a constant cleaning performance." Writes the manufacturer). Furthermore excites me the "info-blue light" that casts a blue dot on the floor under the front door. At the end of the term, the machine will beep as usual, and the lights go out. So I no longer tear during drying the dishwasher on, because I'm not sure if he is already finished) The delivery worked on time and without problems. I managed the installation thanks to the well-illustrated manual itself. Another little tip: If your installation space larger than 608mm (width) or the device are similar to mine in the corner or on the edge of the kitchen, then the side walls do not have enough stability for the supplied screw aside. The machine must then be screwed onto special sheet metal angles to the work surface (front door open accessible). Attention this metal bracket are not included. You have the Mat-No. 622 456 and can be ordered via the Siemens Customer Service. I have broken down this angle from the old machine. The sheets are top, front on the machine is clicking (the slots on the machine are still the same as the old one). But you ordered rather new. Otherwise, I am very satisfied.
