Unfortunately, we often have a problem with the machine which manifests itself as follows: with the capsules for milk or chocolate etc. it often happens that they "explode" and then run out everywhere and splash in all directions. After cleaning, I put in a new capsule and it works as it should. I can't understand why this problem occurs. This has never happened with Delizio coffee capsules. So unfortunately we can throw every 3/4 capsule unused into the waste.
