Starbucks Verismo K-Fee Fix For Pump Running But No Water

Pump running but no water fix for Starbucks Verismo machine. This was a machine given to me which had been sitting for a few years which is why I state when water finally was pouring from the spout that it was dirty.
There might be a cheaper way to do this fix, perhaps just some 3/4 flexible tubing that you could stick in the water inlet and perform the same procedure.
