Saeco Aroma Chrome no longer draws water

Hi everyone
, thanks for the tips on how to jump start the pump, I had a question about Saeco Aroma (chrome/nero) maintenance: Since my machine is probably clogged and I need to take it apart, I thought it would be a good opportunity to change all the seals. The model is still the one with the toggle switches and therefore with safety much more than 10 years old. Can you give me a hint where I can get a useful set of gaskets for the AROMA? I don't know which rings are used and would like to exchange the rings directly when dismantling the machine and not first remove, measure and order all of them.
I am
happy

Tx for the tips. The bike pump was the savior also in our case!
