The small threaded plastic plug pushes the spring that pushed the little black valve. I belive that the plastic plug is not supposed to be screwed tight, because it makes the black rubber valva to shut completely.
i know which part you are referring to. I can't remember if I screwed it on to the max or not. Recently, in another video, I also opened the pump and applied the same way to see if I could fix the issue. It didn't work sadly but after letting the pump run a while, After removing the tank, I just dropped water to where the tank plugs into the machine. After a while the machine slowly took the water in and now my other machine is working. Air locked somewhere beyond the pump perhaps?
I opened the pump, checked everything and put it back in. It didn't change anything in terms of water volume or pressure. Still takes 50 seconds just for an espresso at 2nd bar. There were rusted parts inside the pump, maybe this is the cause? Also, the metal piece that is on the inner side of the electric part of the pump, is free and not glued. I didn't want to do anything to not damage it further. I assume it's either the pump and the issues I mentioned, or the control board not providing the correct power output.
I fixed it! Had to change the o-ring of the piston, and now it's as good as new. I followed these videos ua-cam.com/video/GiboQpj0r8Q/v-deo.html ua-cam.com/video/Q0ax4a7ktnw/v-deo.html. Thank you as well!

Thank you for your video pal, you helped me! :)
Great video! My Mini Me has low pressure - is slow to dispense water. I will give this a try and return to let you know if it was successful.

Glad to hear your problem is solved.
@@eniltoh yeah 😃 and it's still working great after 5 months and 1-2 coffee servings per day 👌🏻
Great!
Am technician but when i try power pump direct it works but when in dolce dont work please help...
probably need to check the board already. I have another which has similar issue with a burnt board
You just disassembled and assembled if you have just tested the pump before like end of video it would have worked.
The issue is something else mate
