My Keurig 2.0 wasn’t pumping water like when it was new . Run vinegar through my machine and cleaned all removal parts with soap and water. I also cleaned the water feed tube ( sharp pointed small stainless tube) which punctures the coffee pod. I used a tip cleaner I had for a cutting torch. Small and flexible. Or you could use a small wire. I found out a drill bit 1/16 might work but not as good. My Keurig is back working about like new.
