We have the machine now for about 1 1/2 years. I can only agree with the previous reviews vollstens. After a short time the problem began with the Bohnennachrutschen. A demand in the product promoter in the media market brought only shake their heads in disbelief that he had something of no customers ever heard. As a tip I was told that I should press the morning before 1 cup dispensing short time in the beans, so they slide better. By the time you get used to everything ... Nevertheless we are angry regularly that the beans do not slide down once in a useless coffee charge in the pulp container disappears, unfortunately not free. Meanwhile, I have at least partially identifies the vulnerabilities: 1. When fall when filling the bean container beans or parts in the area of the switching lever, which unfortunately can not be excluded and often happens, the lever can not be turned over until it stops. Then the inner slider is not at the bottom, forming a barrier. Unfortunately, that's "out fumble" the disturbing beans / pieces in the switch area very difficult (tweezers ...). 2. My guess there is in certain beans a non-recycled "crumb rest", which sets and prevents the slide can not be pushed right to the bottom in the area of the slide mechanism between them and the grinder. One can find good in bean container is empty; it remains a "ridge" as a barrier up. The can not press down with force. As a small "emergency solution" can rumkratzen with a shish kebab in the above gap until the slide goes down completely. As a reminder: We are talking about a brand medication manufactured by the company Melitta in the price segment of up to nearly 1,000 euros !!. Therefore, this lack is not acceptable. Unfortunately, our guarantee will expire in a few months. Because us the product promoter has no hope for a solution, I do not see any chance of success at the service of Melitta (see also previous speakers). I can therefore this product under these premises do not recommend. PS: The rest of the machine is good, temperature, taste and so on! Only very, very loud !!
