Coffee grounds in the coffee and only droplets

We bought this machine, because we have done with two identical machines for years good experience, also with regard to the use of non-original capsules. I also think therefore both machines have ceased operations after four years now.
In one case, the coffee was only thin in drops from the machine. Here I removed the locking unit, soaked in dishwashing solution overnight and reinstalled. In fact, this remedy has created.
The other machine was not unfortunately any longer repaired in this way.
You "spit" after the second cup of coffee grounds and had no end in coffee.
The whole was accompanied by uneven noise of the pump. A change of the pump did not help. This as a reference for all those who observed the same phenomenon.

Why I buy despite two machines identical design nevertheless again a 520er?

Quite simply because the machines have worked for four years very stable and, indeed, industrious. We tested with the Lidl-capsules of the first generation, Esprimo, Zuiano and still several other capsules.
All this has been accepted both machines without complaint. The milk froth is wonderfully tasty and also produce with minimal effort. Users of extreme foamer Aerocchino have the bottom line more work, even when the milk foam from this unit is delicious.

They "eat" all caps, working solid and you have to have no fear that any fuses are installed to prevent the use of non-original capsules.
Such there should be at machines of the latest generation.
The Lattissima 520 fits into any kitchen without taking up too much space, requires little maintenance and makes good, hot coffee.

That's why we bought it again.
