EXPLANATION: It is normal at that type of machines when they stay long unused you may have trouble with pump. The pump has 2 non return valves, very small and very sensitive ones. If they don't work properly the piston of pump cant pump watter for brewing coffee. SOLUTION: 1 - You should replace the pump, it will provide pressure and you will be able to get coffee from coffee brewing outlet 2 - (in case you cant get new pump fast enough) You open the pump carefully, the non return valves are in outlet part of pump. Before opening you can try blowing with compressed air = 4 bar (5-10 seconds) many times that helps to get in order the valves without opening pump.
