How to Fix a Clogged Keurig Coffee Maker: Proven Methods and Troubleshooting Tips

My mornings always start with a cup of steaming hot coffee. As a coffee lover, I rely on my Keurig coffee maker to brew that perfect cup every day. However, like any other appliance, it can sometimes experience issues, such as a clogged Keurig. Don’t worry though, I have discovered some proven methods and troubleshooting tips that will help you fix your clogged Keurig coffee maker and get it back in peak condition. So, let’s dive in and get your beloved coffee maker up and running again!

Identifying a Clogged Keurig Coffee Maker

Before we delve into the solutions, it’s important to understand the signs of a clogged Keurig coffee maker. Some common indicators include slow brewing or no brewing at all, coffee grounds in your cup, unusual noises coming from the machine, or even an error message on the display. If you notice any of these signs, chances are that your Keurig is experiencing a clog. Now, let’s move on to the methods to fix this issue.

Method 1: Cleaning the Needle

One of the main culprits behind a clogged Keurig is a blocked needle. Over time, coffee grounds and debris can accumulate and hinder the flow of water through the needle. To clean it, start by unplugging your Keurig and removing the water reservoir. Locate the needle on the top of the machine and carefully use a paperclip or Keurig’s cleaning tool to unclog it. Gently insert the paperclip into the needle and move it back and forth to dislodge any trapped debris. Once you have cleaned the needle, reassemble the machine and try brewing a cup of coffee. More often than not, this simple step can resolve the clogging issue.

Method 2: Descaling Your Keurig

Another common cause of a clogged Keurig is the accumulation of mineral deposits or scale inside the machine. This happens due to the minerals present in water, especially if you are using hard water. Descaling your Keurig regularly can help prevent clogs and ensure optimal performance. To descale your coffee maker, you will need white vinegar, water, and a sink.

Start by emptying the water reservoir and filling it halfway with white vinegar. Then, fill the rest of the reservoir with water. Place a large mug or container on the drip tray to collect the solution. Run a brewing cycle without inserting a K-Cup, allowing the vinegar-water mixture to flow through the machine. Repeat this process until the reservoir is empty.

Next, rinse the water reservoir and fill it with fresh water. Run multiple brewing cycles with just water to flush out any vinegar residue. Remember to empty the mug or container each time it fills up. Descaling your Keurig at least once every three to six months can significantly reduce the chances of clogs and improve the overall lifespan of your coffee maker.

Troubleshooting Tips for Stubborn Clogs

If the aforementioned methods don’t solve your clogging woes, don’t lose hope. There are a few additional troubleshooting tips you can try to fix your Keurig coffee maker.

1. Check the Water Line

Sometimes, a clog can occur due to an obstruction in the water line of your Keurig. To check for this, turn off your coffee maker and unplug it. Remove the water reservoir and inspect the water line for any blockages. If you notice any debris or residue, clean it out using a soft brush or cloth. Once the water line is clear, reassemble the machine and test it. This step can often resolve clogs that are hindering the water flow.

2. Clean the Brew Head and Filter

Over time, coffee oils and residue can build up in the brew head and filter area, leading to clogging issues. To clean these components, ensure that your Keurig is unplugged and follow the manufacturer’s instructions for removing the brew head. Rinse it under warm water, ensuring that all debris is removed. Similarly, clean the filter with water, making sure it’s free from any obstructions. Once cleaned, reassemble the brew head and filter, and give your Keurig a test run.

3. Use a Different K-Cup

Believe it or not, the type of K-Cup you use can sometimes contribute to clogging problems. If you consistently experience clogs with a particular K-Cup, try using a different brand or variety. Some K-Cups may have finer grounds or faulty design, which can lead to clogs. By switching to a different K-Cup, you may eliminate the clogging issue altogether.

4. Seek Professional Assistance

If none of the above methods work for you, it might be time to seek professional assistance. Contact Keurig’s customer support or take your coffee maker to an authorized service center. Trained technicians will be able to diagnose and fix any underlying issues that may be causing your Keurig to clog.

Preventing Future Clogs

Prevention is always better than a cure, and this holds true for your Keurig coffee maker as well. To avoid clogs in the future, take these preventative measures:

1. Filter Your Water

Using filtered water can significantly reduce the mineral content in your coffee maker, reducing the chances of scale build-up. Consider investing in a water filter or using filtered water from your refrigerator.

2. Clean Regularly

Make a habit of cleaning your Keurig regularly, both internally and externally. Wipe down the machine daily to prevent any accumulation of dirt or debris. Follow the manufacturer’s guidelines for descaling and perform this task at the recommended intervals.

3. Store Properly

When not in use, store your Keurig in a clean and dry environment. Ensure that the water reservoir is empty, and the machine is free from any moisture. This will prevent the growth of mold or bacteria and extend the life of your coffee maker.


There’s nothing worse than a clogged Keurig when you’re in desperate need of your morning coffee fix. However, armed with the methods and tips discussed above, you can confidently tackle any clogging issue that comes your way. Remember, regular maintenance and preventative measures are key to keeping your coffee maker running smoothly. Now, go ahead and pamper yourself with a delicious cup of coffee from your newly unclogged Keurig!
