Now the machine is already 5 1/2 years old and still doing their services excellent. Approximately 1 times a year I had to unclog with a needle and indeed every single Loechchen the sieve. I have always used filtered water and 3 to 6 cups a day, sometimes even 10 (often visit me friends for the good Esspresso). For several months, the machine is heating up at the pumps and also become louder but they do their services weterhin. The sounds are like kettle and I've just observed that the water bubbles in the water tank and is heated as well. Probably some seal no longer OK Now, (I thought) becomes necessary a second time to clean the shower (there where the water flows) and decalcification. So .. thought and done. Now bubbles in the water tank only shortly before the maximum Hezpunkt (where the green LED lights up) and pump is again quiet as in the beginning when the machine was new. Thank DeLonghi. 26/02/15 - After I made the machine clean and drew a brief sample, I wrote the review here. The next day I wanted to make a Esspresso ... "Play me the song of death" - a small cup and half machine suddenly went out by itself. Further operation of the buttons hate no reaction. Then I realized that no current was. Circuit breaker was tripped. When I came back to the machine, I found a great Fuetze around the machine. Sequel follows...
