Thanks for the great video!
I am experiencing an issue with my Magnifica S espresso machine. Seemingly at random, but quite frequently, the water that should flow from the coffee dispenser instead flows directly from the bottom into the drip tray. This happens both during startup, when the dispenser goes through its initial rinse cycle, and when I press the button to perform a rinse. Unlike in your case, the hot water flows only to the drip tray and not in the waste container.
When I attempt to make coffee, the machine starts pumping water, but after a few seconds, it switches to the cleaning and emptying phase for the infuser without dispensing any coffee. The ground coffee accumulates as powder in the waste container. Sometimes, I can temporarily resolve the issue by performing multiple rinses, but only in 50% of the cases am I able to obtain the desired coffee.
On some occasions, however, the machine works correctly right from startup and throughout the coffee dispensing process. Do you think I should replace the pump or the mechanic valve as you did? Thanks again

I have disassembled everything including the mechanical valve to check if everything was okay. The observations are that there are no o-rings consumed, as well as that I see the hot water coming into the mechanical valve but then exiting directly from the little pipe that goes in the steam dispenser/mechanism, and from it the hot water flows from its bottom which is going to the drip tray.
For some reasons, the hot water does not go through the infuser but it exit directly from the mechanical valve.
As I have not seen cracks or orings consumed in the mechanical valve disassembly, I'm thinking about if there is not enough strength for the electrical motor to push the infuser up and somehow preventing the mechanical valve to work as designed.
If you have any view on it it will be great😊

I have the exact same issue and having no luck online, did you solve this?

​@@adamphillips9954 Hi, yes, I solved by buying a kit of o-rings and replaced all of them. Since then the machine works as new, great success :) Even if I did not see any cracked o-ring, they were probably more stiff and they let water through. I bought the kit in amazon.

@@adamphillips9954 I followed all the steps illustrated in the video "Delonghi Brew Piston Infuser Repair | Step by Step"
