When I prepare my double espresso small drops of water (not coffee) that are NOT passing through the portafilter will drop into the cup. I have tried to grind the coffee so that it will be more coarse, or put into the basket smaller quantity -then fewer water drops will appear coming down, but nevertheless they will be there

The group gasket is either dirty, or there is some damage on the basket of the portafilter that is letting the water flow.
