A:Answer I had to replace my older Keurig. I tried resetting and de-liming the machine, but "prime" kept coming up unless I unplugged the machine and restarted each time. It would work, but got very tired of doing this every time I wanted a cup of coffee, so I bought a new smaller machine for the office. Go to You-Tube to see ways to fix your older machine. The reservoir doesn't hold much water and is designed for single use, which is okay, but a hassle to add water each time I use the machine (also needed to keep an unused cup to add water each time). I don't use Keurig at home anymore, for convenience I will use a Nespresso machine or for more coffee a traditional coffee maker with a burr grinder. If I were to compare the taste of each machine, the traditional coffee maker is better. I stopped making coffee with a French press and pour over method because it was more work to do. I hope this was helpful.
