Delonghi Magnifica S - No main spout pressure

As title states, no pressure. Liquid comes only upon first run. When grinding coffee, nothing comes out and it sounds like pump is stuck. Pump is not broken as hot water/steam spout works fine and water comes out hot and with decent pressure.

What done so far:

\* Manualy cleaned heating element

\* Manually cleaned tubes going from heating element to and after brewer unit

\* Cleaned the main spout inside

Any suggestions are extremely welcome!
