Troubleshooting Your Keurig: Resolving 10 Common Issues with Ease

13 min read NOV 12, 2023

Although Keurigs have become more common and accessible nowadays, they have flaws. Occasionally, they may experience breakdowns, requiring troubleshooting to resolve the issues. Fortunately, a comprehensive Keurig troubleshooting guide has been compiled to assist you in avoiding future problems. Continue reading for solutions to common issues with your Keurig coffee maker.

1. Keurig Is Not Turning On

If your Keurig fails to power on when pressing the button, there are three possible reasons:

1. Incorrectly plugged machine: Ensure the machine is properly connected to the power source.

2. Malfunctioning power outlet: Test the outlet with another device to confirm functionality.

3. Failure to directly press the coffee machine's power button: Be certain to press the power button directly without unintentionally missing it.

To effectively resolve any power-related concerns with your Keurig, addressing these potential issues and troubleshooting accordingly is crucial.

To begin, check if the machine is properly plugged in. Ensure that it is securely connected to a power outlet. If it is plugged in correctly but fails to turn on, connect other appliances to the same outlet. The issue lies with the outlet if they also don't turn on.

To resolve this, plug your Keurig into a different power outlet. However, if your outlet is functioning properly and the machine is connected correctly, double-check that you are pressing the power button correctly. For Keurig 2.0s or Keurig Pluses, locate the power icon on the lower right corner of the LCD screen. Tap on it, and a welcome note should appear, indicating that the machine is powered on.

2. Keurig Is Not Brewing

The main causes of brewing issues with your Keurig are air bubbles and debris in the inner tubing. To address debris buildup, try running the machine without a K-cup. You can also effectively flush out the machine using a descaling solution, like a few drops of white vinegar mixed in water.

Afterward, thoroughly rinse the machine with clean water to remove any vinegar residue. Fill the machine's reservoir to the brim with water for air bubbles. Then, unplug the machine and gently shake it to dislodge the air bubbles, restoring your Keurig's proper functioning.

If your Keurig is still not working correctly, there may be misaligned parts. Take a moment to ensure that the handle, water tank, K-cup, cup holder, and lid are securely attached. Also, check if there is enough fresh water in the water tank.

3. Keurig Coffee Tastes Bad

If your coffee tastes unpleasant when brewed with your Keurig machine, there may be a few reasons:

1. It may have been a while since you last cleaned it.

2. You might be using tap water instead of filtered water.

3. The use of low-quality K-cups could also be a factor.

The simplest solution is to switch from tap water to filtered water. It helps prevent the accumulation of scale and coffee grounds, which can adversely affect the taste of your coffee. If you already use filtered water, you may want to consider trying a different K-cup pod.

Sometimes, using low-quality coffee can result in a burnt or excessively acidic flavor in your beverage. Another option is to run the descaling system on your Keurig machine. The specific descaling process may vary depending on your machine model, so it is advisable to consult the manual that came with your machine for the correct instructions.

In general, however, the descaling process involves the following steps:

1. Empty the water reservoir and drip tray.

2. Remove the filter and coffee pods .

3. Mix descaling solution and water in a 1:1 ratio and add it to the machine's tank.

4. Run a descaling cycle according to your model's instructions.

5. Run some cycles of water rinsing.

4. Keurig Doesn't Heat the Water

If your Keurig produces cold coffee instead of a hot cup, several underlying issues could be at play. Firstly, a malfunctioning heat system may result from a damaged water pump. Additionally, the accumulation of calcium and coffee grounds within your Keurig could be causing troublesome clogs. When the water pump malfunctions, it triggers the main heat system to shut down as a protective measure against overheating.

To address this issue, thoroughly cleaning your machine is highly recommended, paying close attention to the bottom of the tank, including the valve and the area where the tank is positioned. Another potential solution is to press and hold the brew button, as this can initiate a machine restart that might resolve the problem.

If neither of these solutions yields positive results, it is possible that your water pump has sustained damage. In such cases, it is advisable to contact Keurig support to obtain a replacement part.

5. Keurig Is Leaking

If your Keurig is leaking, it typically happens from the bottom or during heating. Let's first address leakage from the bottom. This issue has a few possible reasons:

1. The water reservoir may be damaged or overfilled.

2. The o-ring could be damaged.

3. The internal water tank may be damaged.

To resolve these problems, you will generally need to obtain a replacement part. However, you can also try to prevent overfilling the water reservoir and ensure that the water inside is cold. Now, let's discuss leaks during the heating process. The causes for these leaks are slightly different.

Here are some common reasons and their solutions:

1. Ensure that you do not exceed the maximum water line to prevent overfilling the water reservoir.

2. Use a water and vinegar solution to descale the coffee machine if it is clogged.

3. Tighten the upper gasket with a wrench or replace it if damaged.

4. Wipe the puncture needle to remove any coffee grounds or debris that may have accumulated.

6. Keurig Lights Are Blinking

Different Keurig models offer various solutions for addressing blinking lights on the coffee machine. For a Keurig Classic, you can attempt to resolve this issue by pressing the following buttons: Add Water, Medium Cup, and Heat. If the lights continue to blink, follow these steps: ensure the water reservoir is positioned correctly, and run a water-only brew of either 6 or 8 ounces to check if the machine dispenses the correct amount of water (this should stop the blinking lights).

If the problem persists, try changing and reinserting the charcoal filter, and running water to brew until the machine gives the appropriate amount of water. The procedure differs for a Keurig Platinum. For this model, turn off the machine, press and hold the auto-off button, and if applicable, press and hold the buttons for the two available size options or the medium and large size buttons for models that offer three size options.

Release all the buttons once the lights stop blinking and turn off. The brewer will start automatically, or turn it on and begin brewing your coffee. If the Keurig lights continue to flash, it may be necessary to replace the charcoal filter. If you have already descaled your Keurig, but the descale light remains illuminated, resetting your machine might help resolve the issue.

7. Keurig Dispenses an Excessive or Inadequate Amount of Coffee

One common issue that Keurig machines often encounter is when they dispense either too much or too little coffee. If your Keurig dispenses excessively, you can try to clean the puncture needle using a clip made of paper. If this method doesn't solve the problem, follow the steps below:

1. Start by unplugging the machine.

2. Take out the water tank.

3. Take your machine to the sink.

4. Carefully move your brewer upside down.

5. Gently tap the machine's base several times with your palm to dislodge any debris.

6. Reassemble your Keurig.

7. Run a cleansing brew cycle using only water.

On the other hand, if your Keurig is dispensing too little coffee, it could be due to a clog. In such cases, cleaning the entrance and exit needles is recommended, and then running several water-only brew cycles to clear the clog. If the problem persists, you may need to descale the machine to remove any buildup in the water line.

8. Keurig coffee leaves residue in the cup

Occasionally, you may find coffee grounds left behind in your cup when using your Keurig coffee maker. There are a few potential reasons for this occurrence. Firstly, using distilled or softened water in your machine can lead to coffee grounds in your cup. To address this, consider switching to bottled water and running a few cycles with only water before inserting a new K-cup. Another possible cause could be a clogged exit needle. Ensure that you clean it thoroughly and run multiple brews with water only.

Using a reusable filter with an incorrect grind size can also result in this issue. It is crucial to consult the instruction manual and confirm which grind size suits your filter. In general, it is advisable to use coarsely ground coffee when utilizing reusable filters.

9. Keurig Shows "Add Water," But It's Full

Sometimes, your machine may ask you to add water even when the reservoir is full. It can happen due to different factors, such as an improperly positioned water reservoir, a clogged water filter, or a dirty machine. It's recommended to start with the simplest solution, which involves repositioning the water reservoir to ensure that its magnetic contacts align with those on your coffee maker. If repositioning doesn't solve the issue, you can proceed to clean both the filter and reservoir. To do this:

1. Use water that is warm with a few drops of dishwashing liquid to gently clean the filter.

2. Wipe the reservoir with a damp cloth.

3. Inspect the machine's filter to ensure it's clean and unclogged.

It may also be worth checking and cleaning the valve beneath the machine, as it can get obstructed too. Remember that a clogged valve can contribute to the problem. Lastly, don't forget the importance of cleaning the machine's exit needles. Following these steps, you can effectively address any issues related to your machine's water supply.

10 Keurig Keeps Turning Off

When your Keurig keeps turning off on its own, it can be frustrating and prevent you from enjoying your cup of joe. This issue is often caused by your specific Keurig model's auto-on/off or energy-saving features. For example, with the Keurig Mini, you may notice the machine turning off after 90 seconds.

However, if it shuts off immediately, there may be a different underlying problem. In such cases, it's important to check if the magnets on your water tank are properly aligned. Misalignment of these magnets can lead to unexpected shutdowns. You can disable the auto-off feature if you own a newer Keurig machine. It will prevent the machine from turning off before you've had a chance to brew your coffee.

When the feature is enabled, a green indicator light will be illuminated, indicating that the brewer will shut off after two hours. To disable it, simply press the Auto-off button to turn off the green indicator light.

Alternatively, you can disable this feature through the LCD menu for newer models. By pressing the left button multiple times until the display shows 'off,' you can easily turn off the auto-off feature. By addressing these issues and adjusting the settings accordingly, you can ensure a seamless brewing experience with your Keurig coffee maker.

How to Reset a Keurig Machine

Resetting your Keurig machine is a breeze with newer models. Simply navigate to the LCD menu and choose the factory reset option. However, the process is a bit different if you own one of the older or more affordable models like the K-Slim or K-Mini. In that case, follow these steps:

1. Turn off and unplug your Keurig machine, and remove the water tank.

2. Leave it unplugged, ensuring the reservoir is not attached.

3. After a few minutes or even a couple of hours, plug your machine back in.

4. Switch on your Keurig coffee maker and reattach the water reservoir, ensuring proper positioning.

If the previous procedure doesn't yield results, try the following steps:

1. Disconnect and reconnect your machine.

2. Open and close the lid.

3. Press and hold the power button.

4. While holding the power button, simultaneously press the buttons for small, medium, and large cup sizes.

5. The machine will automatically pump to prime itself.

6. It should now be functioning correctly.

I use plastic cups with paper filters. The machine does not close well, even when using an empty cup. I have to use both hands to push it down then it snaps shut. Is this normal?


I am ordering a new Keuring. What is difference between a K- Mini and a K-Express?

Pat Bergeron

We have a Keurig 2.0 and my husband says it’s not heating the water hot enough. He says after the brewing he has to put the cup of coffee in the microwave to get it good and hot. The hottest I could get it to heat to was 150F to 152F. I watched a video of one that heated to 190F. Is this the the hottest we can expect from this machine? Apparently it used to be very hot but not anymore. I know this isn’t one of the more expensive machines but is there something we can do to fix this problem other than buying a new one.

Dan Bobocel

My Keurig is a useless piece of junk, I had one for about 5 years and it worked good, it finally quit working. I bought a new K-Elite , it worked for about one week and every time you turn it on it stays on for about 30seconds on shuts down, I have tried all the solutions that were given on your website and it still doesn’t work

Ed Kennedy

Second time descaling. First was a breeze.
The descale light was on after 3 rinses. This morning the only light working is descale and brew light. Power and size lights no longer work. But it brews coffee

Valerie Peasley

My “descale” light came on, I “descaled” per instructions on package. The light remains on. I unplugged the machine, let it set overnight, plugged it back in, the light remains on. What should I do?

Kevin P Daly

$300 for a K155. Less than 2 months and it won’t heat the water nor will it brew. What a colossal waste of money. Tried calling support, could barely understand them and then they wanted to walk me through taking the thing apart. If I have my say, we will not be purchasing any more of these and will go back to coffee makers that actually work.


I’m now on our 3rd Keurig. The first one was fine but, the “hatch” would not close without jiggling. So we bought ourselves a few one (12/22) a Keurig K-Cafe SMART, but now 18 mos later, the display is on the fritz and I can’t see what brew I am making. Contacted Keurig, they told me that they would replace it (Free) I just needed to submit pix of Serial No and purchase info, which I promptly did, thinking that Keurig would get me a replacement for free. But, oh no. Not so fast! The current machine is conveniently past the 1 year warranty! So they recinded the offer of sending me a replacement machine for free, instead offering me a 50% off on any listprice of one of the home brew + free standard shipping. We use the brewer to make about 4 cups of coffee per day. I expected higher quality and craftmanship from Keurig but, clearly I was misstaken! How long will the next one last?

Keurig K-Slim. Six months of use once a day. Descaling light came on. Read instructions on how to descale machine, I’ m not a “wing it” person. After descaling the machine shut off and died. Followed troubleshooting tips but machine won’t work. Manufactured in China yes BUT, your name is on it!!

Dave Allison

Bought my machine 6 months ago at Kohls. Bought the coffee and iPod combo. Lights turn on and then shuts off. Tried everything on troubleshooting. Called Kohls and they will not help me. I had a bunn for 10 years and never let me down on coffee side. What a waste of money

Jane Seidel

2nd Kurig. First one lasted about 5 years. This one, less than 2 and not used 2 months of the year, at least, and never on a daily basis. Only one coffee drinker and only one cup per day. Just finished the descaling routine (using the $7.98 solution) and now no power to the machine. Yes, I’ve tried all the suggested troubleshooting tricks. Going shopping, but not for another Kurig.


Machine literally just stops working, its like an iphone they just want you to buy another

Steven Ielmini

I just replaced my Keurig in December 2023 and now it would turn on. I tried resetting the machine as per your website. It directed me to contact you. Can you help? Thanks


Machine will not turn on I Have tried all suggestions

Judy Batson

My coffee maker isn’t working.
I tried all your helpful hints. Can I get it replaced.

Terry Wright

My brand new Keurig that cost hundreds of dollars has, in its lifetime, heated the princely total of 2 oz of water. It sucks up and heats the water, the select cup lights come on and … nothing … they stay on regardless of your clever attempts to press the button. This is what you get when a company spends more effort building a brand and marketing than building a well engineered and constructed product. Went online and bought the cheapest single cup coffee maker available. Plug it in and … presto … lovely coffee every time. At the end of the day, all it is doing is heating up and dribbling out a few ounces of water. Not exactly rocket science. Sometimes the simplest solution is the most elegant one. Bye bye, Keurig.

Kevin Holzhauser

I’ve tried everything suggested and still can’t get descale light to go out.


Bought a new Kuerig K-express. (6-18-04) Did everything that was in the instruction. The lights will blink (as they should). Would not brew. Lights shut off. Unplugged it for 10 minutes to reset it at least 15 times.

Bill Collar

My wife loves her morning and the convenience of her Keurig. She is on her 4th Keurig and now it fails to turn on. Each one has lasted about two years. She has been doing the recommended cleaning. What is the expected lifespan of a new Keurig. She has about 3-4 cups a day. We usually purchase a middle priced model. Is it time to purchase another or is every fifth one free?
I am 80 years old, have been married 58 years and I hate to see our marriage dissolve because we can’t afford another new Keurig. What do you suggest?


Will not turn on. Tried all suggestions. No life . It’s dead. Purchased from qvc . Christmas time 2023. It’s had. Very easy life. Disappointing

Johamilly Torres

This is the 2nd Keurig I purchased in such a short time & I just realized is if I wash it in the sink with water & soap all the lights stay flashing once dry & set to make some coffee but it doesn’t work. If there is a solution please put it on the label not to wash or rinse. I won’t purchase another one I thought the 1st time it was my mom using it but now I see it’s because we washed it. I don’t want to assume you’re not supposed to clean the device because that would be very disturbing & disgusting. Thanks in advance!


I have only had my mini Keurig for 4 weeks and it stopped working. No lights and it won’t turn on. It is DEAD. I am bummed! I thought this saw a good brand.


I have the exact same problem as Vickie posted on June 11!
I unplugged machine and made sure the water tank is seated properly. Tried several times and the machine keeps turning itself off! Any suggestions out there? I thought maybe it needed to be descaled but it won’t even let me do that!

Cadet Henderson

“Like a few drips of vinegar”. All other recommendations say a bottle of descaling liquid or vinegar mixed 50/50. Please correct note.
