Thank you all, fixed it myself after calling Keurig support, telling him I did all the usual cleaning suggestions in the manual only to find the water draining back into the reservoir. He seemed to think this was not only odd but was probably due to a malfunctioning motor, and a new Keurig was the solution. I decided to explore online to see if others had this problem and here you are. Helped to poke up the valve that disperses coffee With paper clip, and blew on the white return valve into the reservoir. It started working, slowly so blew again on return valve, then more vinegar water flushing, it’s is perfect. Now, no thanks to KEURIG.
