Instructions for pump replacement Saeco Cafe Prima

Hello. I have a Saeco Cafe Prima with which I am very satisfied. Recently, however, there has been a problem with coffee dripping out very slowly. The Pumpengeräusch is much louder than before. I suspect the pump is defective. Is that true?
I find the spare part on the web but no manual für the repair. Can anybody help me?
Many thanks in advance and a happy new year to all of you.

If you have them then times with descaler with Amidosulfonsäure descalkt?
Sicherlich you can change the pump.
Schau mal nach Saeco Vienna Pumpe ausgetauschtche. (identical KVA)
MfG Chris
