I had just been about 9 years surprised that coffee machine in use and was, as I have found exactly this machine (identical) again on Amazon. Before first so the machine has to be flushed with clean water. After after the 2nd rinse the water in the pot was still milky white, I've attached a third rinse, with the same result. In filter element and in the hole of the can lid, a white deposit has settled. The customer service of Melitta could not explain that too. I was sent a return form, the I found in my mailbox the next day. I immediately sent and after 3 days I was in possession of a new machine, the machine. I have forgiven the 5 points because of the prompt delivery and exchange because of the friendly and courteous customer service. From the quality I could convince already in the past nine years with the predecessor engine me yes.
