No water or liquid came out, only powders in the bin box. help :(

I bought this machine almost 20 yrs ago, I didn't have a chance to use it. I tested it this morning. Firstly, I tried to clean the pipes inside. I followed the instructions from the website, but no liquid came out. I gave up trying; and and then I wanted to let it make a cup of coffee. Then I realized that it would not make any liquid at all!

The water tank was checked, and it was fine. WHERE is the problem? Wrong operation of the cleaning? or I should have a magic spell to wake a "new" machine up? HLEP:((((((((
