How To Fix Keurig Prime Error? Complete Solution

When your Keurig coffee machine says prime, you need to prime the machine to brew a cup of coffee. When your Keurig 2.0 or 2.0 K500 brewer displays the word prime, your brewer has trouble making the necessary water pressure to push water through the K-Cup, filter, and into your cup of coffee. There are several reasons why this could happen and how you can fix it to brew your morning cup of joe.

What is the issue with Keurig prime membership?

The problem with Keurig Prime is that it’s not always accurate. Sometimes it says coffee is ready when it’s not, or it takes too long to brew a cup. This can be frustrating for customers trying to get their morning caffeine fix. You can do a few things to try and fix this issue.

Check the reservoir on the machine. If there isn’t enough water in the tank, your machine will struggle to produce enough pressure to make a full cup of coffee. Fill up the reservoir if needed. 

If your Keurig was accidentally unplugged or turned off, plug it back in and turn it back on. That should solve the problem quickly and easily.

You might also want to look at what size pod you’re using if your machine doesn’t seem like it’s working correctly. It might just need more time to work its magic.

Reasons behind Keurig prime issues

The most common reason for a Keurig not priming is that it needs to be descaled. This can happen if you don’t use your brewer regularly or live in an area with hard water. If your Keurig displays the prime error message, the pump is not working correctly and needs to be replaced. Sometimes, simply unplugging the machine and plugging it back in will reset the pump and fix the issue. (Enjoying this blog?

Other times, you may need to descale your machine or replace the pump. To descale, run two cycles of water through without adding any K-Cups. After that, fill the reservoir and let it brew just one cup of hot water before running another two cycles of plain water. To replace the pump on a 2.0 model, follow these steps:

  • Make sure the unit is powered off.
  • Remove all parts from inside the unit.
  • Locate where the old pump was connected.
  • Put a new screw on top of the new replacement part at the connection point.
  • Put a new replacement part in place and reassemble Keurig as per original directions.

First, unplug the machine and wait a minute before plugging it back in. If that doesn’t work, hold the brew button for five seconds. If it is unsuccessful, you might need to descale your machine.

You can do this by following these steps: Run two cups of water through the machine without any K-Cups inserted. After this, use one cup of white vinegar to rinse the reservoir and dispenser lines inside. Pour white vinegar into both openings on top of the reservoir until they’re complete, then let it sit for 30 minutes with a paper towel covering them (to keep spills contained).

Afterward, run another two cups of water without any K-Cups inserted again. Rinse out any remaining vinegar residue with cool water (make sure not to touch or move anything while doing so). And finally, run three cups of clean water through with no K-Cups inserted before using your Keurig again.
