When the machine is working properly, there is a burst of air that empties the remainder of fluid in the k-cup. This stopped happening after a recent descaling. The result is a partially-empty K-cup that leaks the remaining coffee or tea after you open the machine in order to remove the used K-cup. I leave my coffee cup underneath to capture the additional coffee, but the machine is clearly missing a step before completing the cycle.
I’ve decaled the machine twice and also cleaned all needles (entry and exit), but I know the problem is with the missing air flow step or whatever that rush of steam is.
