How To Prime A Keurig


Keurig is a popular brand of single-serve coffee makers that has become a household name in recent years. With their easy-to-use design and a wide variety of coffee and tea pods, Keurig machines have revolutionized the way people enjoy their morning cup of joe. However, like any coffee maker, Keurig machines require regular maintenance to ensure they continue to function properly and produce a high-quality brew.

How To Prime A Keurig

One essential part of Keurig maintenance is priming the machine. Priming helps to remove any air bubbles from the water lines, which can cause the machine to malfunction or produce weak or inconsistent coffee.

It’s an easy process that only takes a few minutes, but it’s important to do it correctly to ensure the best possible performance from your Keurig machine.

In this article, we will provide a step-by-step guide on how to prime your Keurig machine properly. Whether you’re a seasoned Keurig user or just getting started with your first machine, this guide will help you keep your machine in top shape and ensure that you always get a great-tasting cup of coffee.

What is Priming, and Why is it Important?

Priming is a process that involves running water through your Keurig coffee maker to remove any air pockets that may have formed during storage or transportation. These air pockets can cause your coffee maker to malfunction, resulting in weak or no coffee output, or in some cases, the machine may not work at all.

Priming your Keurig coffee maker ensures that water flows through the machine smoothly and that you get a fresh cup of coffee every time you brew.

Tools You’ll Need:

Before we get into the process of priming your Keurig coffee maker, let’s first discuss the tools you’ll need. These are:

  • A Keurig coffee maker
  • A cup or mug
  • Clean, fresh water

Step-by-Step Guide to Priming Your Keurig Coffee Maker

Now that you have all the tools you need let’s dive into the step-by-step guide to priming your Keurig coffee maker:

Step 1: Fill the Water Reservoir

The first step in priming your Keurig coffee maker is to fill the water reservoir with clean, fresh water. Ensure that the water level is between the minimum and maximum fill lines on the reservoir. Remove packaging from Keurig. Rinse the water reservoir. Fill it.

Step 2: Power On the Machine

Once you have filled the water reservoir, plug in your Keurig coffee maker and turn it on. You should see the power indicator light turn on, indicating that the machine is ready to use.

Step 3: Place a Cup or Mug on the Drip Tray

Place a cup or mug on the drip tray of your Keurig coffee maker. The drip tray is the small tray located at the bottom of the machine that collects any excess water or coffee. Ensure that the cup or mug is large enough to hold the amount of water you plan to run through the machine during the priming process.

Step 4: Run Water Through the Machine

Press the brew button on your Keurig coffee maker and let the water run through the machine and into the cup or mug. You may need to press the brew button a few times to ensure that all the air pockets are removed from the machine. You will notice that the water may have a strange taste or color during the first few runs. This is normal, and it is due to the manufacturing process of the machine.

Step 5: Discard the Water

Once you have run enough water through the machine, discard the water in the cup or mug. You can pour the water down the sink or use it to water your plants.

Step 6: Repeat the Process

Run water through the machine and discard it. Repeat until the water runs clear and has no strange taste or color. This step may take a few minutes, depending on the model of your Keurig coffee maker.

Step 7: Install the K-Cup

To brew coffee with Keurig, first prime it. Install K-Cup and brew. If Keurig hasn’t been used in a while, prime again before brewing.

Tips for Maintaining Your Keurig Coffee Maker

Now that you know how to prime your Keurig coffee maker let’s discuss some tips for maintaining it to ensure that it lasts longer and delivers fresh, delicious coffee every time.

Clean your Keurig coffee maker regularly:

Regular cleaning of your Keurig coffee maker can help prevent clogging and ensure that your coffee tastes fresh. You can use a mixture of vinegar and water or a Keurig descaling solution to clean your machine.

Use filtered water:

Using filtered water can help prevent mineral buildup in your Keurig coffee maker, which can affect the taste and performance of your machine.

Replace the water filter:

Replace the water filter in your Keurig every two months or as per the manufacturer’s recommendation.

Empty the water reservoir:

If you are not going to use your Keurig coffee maker for an extended period, ensure that you empty the water reservoir to prevent bacteria growth and mineral buildup.


Why do I need to prime my Keurig?

Priming your Keurig is important because it ensures that there is no air in the water line, which can prevent proper brewing and damage the machine over time.

How do I prime my Keurig?

How often should I prime my Keurig?

It's recommended to prime your Keurig every time you refill the water reservoir or after a period of inactivity. This ensures that the water line is clear of air bubbles.

Can I use vinegar to prime my Keurig?

It's not recommended to use vinegar to prime your Keurig. While vinegar can help remove mineral buildup, it can also leave behind a strong odor and taste that may affect the flavor of your coffee. Instead, use clean, filtered water to prime your machine.


Priming your Keurig coffee maker is a simple process that ensures your machine works correctly and delivers fresh coffee every time. By following the steps outlined in this article and maintaining your Keurig coffee maker regularly, you can enjoy delicious coffee for years to come.
