On the machine, I do not want to go big here that others have done at this point already. We have for 3 years, you will find super and no longer want to do without them, but it was only since then everything works with the milk froth ....! After a certain well-functioning early days we had, in fact even the milk froth problem "also get the other Cappucinotrinker obviously inevitably with this machine. But that need not be so. As with us the problem occurred for the first time we cleaned at first the milk nozzle and it was better by -. but unfortunately not in the long run Eventually it became worse again and with a cleaning milk nozzle it was not done then we have the machine out of order several times entkalt and thereby the milk foam was slightly better, but also not really good. as at the beginning. However, we thought that if descale improvement achieved, we are on the right track. It was the same. We have screwed and determined that the hard plastic hoses were right behind the valves inside the machine totally clogged with lime machine . And although we adhered strictly to the Entkalkungsvorgaben the machine and the water hardness was set correctly. We then removed the tubes from the lime and the water hardness set a grade harder. This we must indeed descale frequently, but have since adjusted to 1 year, no more and again problems super milk foam. Conclusion: If this machine buys new does well, the degree of water hardness by 1 degree to be adjusted upwards. Who has been the problem needs to open someone trusts the device. Alternatively, the sales service, the problem was supposed to run in the first 3 years still under warranty. A further tip relates to the purification of the brewing unit.
