So I have taken out the filter tray, check if the spring nor did your service and lo and behold, they began to drone. Nevertheless, I have kept the whole time under water, rinsed and decalcified. Nevertheless drips and drips and drips it. Meanwhile, I have three times a week to clean the heating plate, because it is otherwise too dirty.
Then I signed up with Amazon, and returned the thing. In addition, I have now a Philips HD 7761 indulged instead. Just hope that the problem does not occur there, too. But as I said, one year and no longer think I already meager. The machine was always kept me in good shape. Decalcification was performed every 60 days (timer), since I use the coffee almost daily.
