Few reviewers complain about the low drying effect, which also suggested me that this may be somewhat exaggerated claims had. We have now tried all the programs and each time the dish is clean, but -also by adequate Nachtrocknungszeit- "soaking wet" back! To that we all dripping water when removing the upper deck. As I remembered immediately the eternal Gag my colleagues: "Do you want something from Siemens or equal to what clever?" Had I taken the time exceptionally seriously. Our nearly 17 years! NEFF old machine has your job to the end much better done, even if these so had not a great, blue Lichtlein, about here are all looking so ;-) If the dishes come clean and dry from the dishwasher, we were already satisfied. Andernfals can better equal Hand wash! The delivery worked perfectly. The installation and attaching the diaphragm were not a big problem, but you should be somewhat versed technically and have a small selection of tools. The holes for the front panel fixings have to be pre-drilled for example neat - how fast the drill is to come forward out again - It looks really stupid ;-) The socket for mounting machines should always by the way next to it, to be installed in the sink base cabinet for example and not behind it, otherwise it is often not suitable for the plug in the deep! (Just as a note, because here some Amazonis have complained about exactly ;-)
