I have about 10 (!) Years ago bought a commercially used Jura impressa X90 and immediately given into the maintenance. When it came back with several spare parts for about 200 €, I mothballed it as a "replacement machine" (wrapped in foil in the basement), because I still had a well-functioning machine. Now I want to put it into operation after all these years and everything seems to work so far mechanically/electrically, but not a drop of water seems to arrive in the machine: After the first "fill system / press steam" the pump works extremely loud (probably because it runs dry), no drop ever comes out of any spout, not even into the drip tray. At some point the machine shows ready, but instead of making coffee dry ground powder comes into the marc container, the machine shows "fill system / press steam" again and the game starts all over again. Haven't opened the Jura yet, just checked the tank water drain, it works great. My question: what could be the cause and where do I start and how to get the machine going?
Many thanks in advance,
