3 Easy Steps to Prime Your Keurig Machine

Published 7 July 2026

Priming your Keurig machine is a crucial step to ensure its optimal performance and longevity. This process involves running hot water through the machine's internal components to remove any air bubbles or impurities that may impede its functionality. By priming your Keurig regularly, you can prevent clogs, maintain the machine's brewing temperature, and prolong its lifespan. Moreover, it is a straightforward and quick procedure that can be completed within minutes, leaving you with a machine that delivers consistently delicious cups of coffee or tea.

To begin the priming process, fill the water reservoir with fresh, cold water. Insert a cup or mug into the drip tray and lower the brew head. Turn on the machine and press the smallest brew size button to start the priming cycle. As the hot water flows through the machine, you may hear some gurgling or sputtering sounds. This is normal and indicates that air bubbles are being removed from the system. Once the cycle is complete, discard the cup of water and your Keurig is now primed and ready to brew your favorite beverages.

Regularly priming your Keurig machine is highly recommended to maintain its peak performance. It is particularly important to prime the machine if it has been sitting idle for an extended period or if you have recently refilled the water reservoir. By adhering to a regular priming schedule, you can minimize the risk of clogs, ensure proper brewing temperatures, and extend the life of your Keurig machine. Additionally, it only takes a few minutes to prime the machine, so it is a small investment of time that can yield significant benefits in the long run.

Preparing the Keurig Machine

To ensure your Keurig machine functions optimally, priming is an essential step to remove any air bubbles or residual water from the system. This process helps create a consistent and flavorful brewing experience.

1. Gather Necessary Equipment:

Before commencing the priming process, ensure you have the following items readily available:

• Keurig machine
• Large mug or cup (at least 10 ounces)
• Fresh, cold water

To maximize the effectiveness of priming, consider using filtered or bottled water. Tap water may contain impurities that could affect the taste of brewed coffee or clog the machine's internal components.

2. Fill Water Reservoir:

Open the water reservoir lid and fill it to the indicated "MAX" line with fresh, cold water. Ensure the reservoir is not overfilled, as excess water could spill during the priming process.

3. Insert Empty Mug:

Place an empty mug or cup with a capacity of at least 10 ounces under the machine's brew head. This will collect the water dispensed during the priming cycle.

4. Power on Keurig Machine:

Plug the Keurig machine into a power outlet and turn it on. The power button is typically located on the front or side of the unit.

Filling the Water Reservoir

To prime your Keurig machine effectively, it's crucial to fill the water reservoir accurately. Here's a step-by-step guide to assist you:

1. Locate and Remove the Water Reservoir

Identify the water reservoir on your Keurig machine. Gently lift it upwards to detach it from the machine.

2. Fill the Water Reservoir with Fresh, Cold Water

Use clean, cold water to fill the reservoir. Avoid using hot or distilled water, as they can damage the machine. Fill the reservoir to the indicated "MAX" line. Never overfill it.

3. Reinsert the Water Reservoir

Once the reservoir is filled, carefully align it with the base of the machine and gently push it back into place until it locks securely.

Additional Tips
