My Keurig Says to Add Water but It’s Full: 13 Ways to Fix It Now!

Table of contents

Well, I’m sure you’ve been there. You’ve got your Keurig set up, you’ve got a great mug of coffee brewing, and then… Your Keurig tells you to add water. Maybe it’s been happening a lot lately. Maybe it’s just starting to happen?

Either way, it can be frustrating when your Keurig asks for more water when it knows the reservoir is full. But don’t worry! There’s a solution.

1. Check if the water reservoir is truly full

There are times when the reservoir may appear to be full, but it actually not. You first need to take the tank off and empty it. This is going to let you know that the tank is full. Refill the tank and replace it, ensuring that the magnet attaches and that the tank is fully secured.

Carefully remove the water reservoir from your Keurig machine.
Check the water level indicator on the side of the reservoir. It should indicate the maximum fill line or be visibly close to the top.
If the water level appears low or below the fill line, then it is not truly full. In this case, empty any remaining water from the reservoir.
Refill the water reservoir with fresh, clean water. Ensure that you fill it up to the maximum fill line or close to the top.
Once the reservoir is filled, carefully place it back onto the Keurig machine.
Make sure that the reservoir is securely and properly positioned. It should align with the machine’s inlet and outlet correctly.
Check if the magnet in the reservoir is securely attached to its designated spot on the machine. This magnet helps in detecting the water level.
Ensure that the water reservoir is fully secured in its place and properly seated. Any misalignment or loose connection can prevent the machine from detecting the water level accurately.
Power on your Keurig and check if the “Add Water” message has disappeared.
If the message persists, try other troubleshooting steps to identify and resolve any potential issues causing your Keurig to display incorrect water level messages.

2. Check if the water line is kinked

One of the most common reasons for a Keurig not working is because there’s no water flowing through the line. If your Keurig says “add water,” but you know it’s full, there may be a kink in your water line. Kinks in any part of the line can cause coffee makers to malfunction and not brew properly. If this is happening to you and you want to fix it yourself instead of calling an expert or buying a new machine, here are some steps:

Check for kinks in your water line. You can do this by turning off the power to your Keurig, removing the cover from underneath it, and looking for any kinks in your water line. If there is one, try using a thin stick or hose to push out any air bubbles and kinks until they’re gone from inside the machine as well as outside (this might take several tries).

If there aren’t any obvious kinks but your machine still isn’t working properly, you may have to consider replacing your entire water line!

3. Check if the coffee grounds are clogged

Another issue may be a clog in the coffee grounds. This could be a clog in the coffee grounds in the K cup, which can make it appear that the water cannot go through and the brew cycle cannot complete.

Here’s how you can check and address this:

Turn off and unplug your Keurig machine to ensure safety.
Lift the handle to open the chamber where you insert the K-Cup.
Inspect the needle that punctures the K-Cup for any visible blockage or coffee grounds.
If you see any clogs, use a paperclip or a similar tool to gently remove the debris. Be careful not to damage the needle or any other parts of the machine.
After removing the visible blockage, close the chamber and make sure it is securely latched.
If you suspect there may be more coffee grounds clogging the system, perform a cleansing brew without a K-Cup. This will help flush out any remaining debris.
Fill the water reservoir with enough water for a cleansing brew and place an empty mug on the drip tray.
Power on your Keurig and initiate a brew cycle without inserting a K-Cup. Allow the machine to run as if making a regular cup of coffee.
The machine will dispense hot water into the mug, helping to clear out any remaining coffee grounds or blockages.
Once the cleansing brew is complete, discard the hot water from the mug and inspect it for any additional debris.
Rinse out the water reservoir and refill it with fresh water for brewing your desired beverage.

4. Check if the exit needle is clogged

The exit needle, or the needle where the water comes out of the Keurig into the K cup, goes down through the cup and into your mug. This needle can become clogged; it can become overly full; and it can get clogged with coffee grounds, sugar, and more.

If your Keurig says to add water but it’s full, one possible reason could be a clogged exit needle. Here’s a more detailed explanation of how to check for and resolve this issue:

Turn off and unplug your Keurig machine to ensure safety.
Lift the handle of the machine to open the chamber where you insert the K-Cup.
Take a close look at the small needle or pin inside the chamber. This is the exit needle responsible for puncturing the K-Cup during the brewing process.
Inspect the exit needle for any visible signs of clogging, such as coffee grounds or other debris.
If you notice any blockage, you can use a paperclip or a similar tool to carefully unclog the exit needle. Straighten out the paperclip and insert it into the needle, gently moving it around to dislodge any clogs. Be cautious not to apply excessive force or damage the needle.
Once you have cleared any visible debris from the exit needle, close the chamber by lowering the handle back down.
Fill the water reservoir with enough water to perform a cleansing brew and place an empty mug on the drip tray.
Power on your Keurig and initiate a brew cycle without inserting a K-Cup. This will help flush out any remaining debris from the exit needle.
The machine will dispense hot water into the mug, effectively clearing out any lingering clogs in the exit needle.
Once the cleansing brew is complete, discard the hot water from the mug and inspect it for any additional debris.
Rinse out the water reservoir and refill it with fresh water before attempting to brew your desired beverage.

5. Check and replace the filter

You may be dealing with an old water filter as well. If the water filter is old, it may not allow the sensor to tell that there is water in the tank. To replace your filter, follow these steps:

Remove the old filter. The reservoir is most often located on the left side of the machine. You need to remove the reservoir and locate the filter compartment.
Remove the filter assembly and remove the old filter. You then need to make sure that there is nothing else in the reservoir that is causing issues with the filter and how it reads out.
Soak your new filter in water for about five to ten minutes. This is going to remove any debris that might be present in the new filter and keep it from going into the machine itself and the water system.
Rinse the filter under running water for about 60 seconds.
Rinse the filter holder.
Place the new filter into the filter holder and put it back into the machine.
These filters last for about two months, depending on how often you use them and how hard your water is.

6. Check the magnet sensor

The first thing you should do when your Keurig says to add water but it’s full is to make sure that the magnet sensor is in place properly. If the water reservoir’s magnet is not in place, brewing will stop.

To check this, turn off your Keurig, unplug it from its power source and remove the water reservoir. You’ll see a small black disc with a magnet attached to it on the underside of the reservoir lid. This is called a “magnet sensor.”

This magnet sensor acts as a sensor to detect the water level of the Keurig tank. If you can’t find your magnet sensor or if it appears to be damaged or misaligned, contact Keurig customer service for help!

7. Try thoroughly cleaning the coffee machine

Still, another problem that you might have, is that your machine is dirty. You may need to do a full system clean-up to remove any scale or build-up that is in the machine itself.

You want to clean the reservoir, clean the tubes, clean the filter, clean the needle, and any other part that you can. You can also run white vinegar mixed with water through the machine to help take out any dirt or scale that might be on the inside of the machine.

8. Try the spanking method

The “spanking method” is an unconventional but sometimes effective technique that you can try if your Keurig says to add water but it’s full. Here’s how you can attempt this method:

Ensure that your Keurig machine is turned off and unplugged for safety.
Carefully lift the water reservoir off the machine and set it aside.
With the reservoir removed, turn the Keurig upside down, so the bottom of the machine is facing upward.
Hold the machine securely and give it a few firm but gentle taps on the bottom with the palm of your hand or a soft object like a wooden spoon.
The idea behind the “spanking method” is to dislodge any potential blockages or air bubbles that may be affecting the water flow or water level sensor.
After tapping, carefully turn the machine back to its upright position.
Reattach the water reservoir, ensuring it is properly aligned and securely seated on the machine.
Plug in your Keurig and turn it on.
Check if the “Add Water” message has disappeared, indicating that the issue may have been resolved.

9. Try resetting the Keurig

If that does not work, you may want to try to reset your machine. To do that, follow these steps:

First, turn off the Keurig by pressing the off button, then, unplug the Keurig.
Remove the reservoir before you plug your coffee maker back in.
Leave it all unplugged for a few minutes.
After that, plug your machine back in and turn it on.
Put the water reservoir back on.
Open the k cup holder and then close it again

10. Clean the reservoir tank

Cleaning the reservoir tank of your Keurig machine is an important step if your Keurig says to add water but it’s full. Here’s how you can clean the reservoir tank:

Start by turning off and unplugging your Keurig machine for safety.
Remove the water reservoir from the machine by lifting it off carefully.
Empty any remaining water from the reservoir into the sink.
Depending on the manufacturer’s instructions, you may be able to disassemble the reservoir for a more thorough cleaning. If so, follow the specific disassembly instructions provided in your user manual.
If disassembly is not possible or not recommended, you can proceed with cleaning the reservoir while it is intact.
Wash the reservoir with mild dish soap and warm water. Use a soft sponge or cloth to gently scrub the inside and outside of the reservoir.
Pay special attention to any areas that may have buildup, such as the bottom or corners of the reservoir.
Rinse the reservoir thoroughly to remove any soap residue.
Inspect the opening of the reservoir for any clogs or deposits. Use a soft brush, such as a toothbrush, to clean these areas if necessary.
If there are stubborn mineral deposits, you can soak the reservoir in a mixture of equal parts water and white vinegar for about 30 minutes. This can help dissolve and remove mineral buildup.
After soaking, rinse the reservoir well to remove any vinegar residue.
Allow the reservoir to air dry completely before reattaching it to the Keurig machine.
Once the reservoir is dry, securely place it back onto the machine, ensuring proper alignment and attachment.

11. Readjust the water reservoir tank

If your Keurig says to add water but it’s full, readjusting the water reservoir tank may help resolve the issue. Here’s how you can do it:

Start by turning off and unplugging your Keurig machine for safety.
Carefully remove the water reservoir from the machine by lifting it off.
Empty any remaining water from the reservoir into the sink.
Inspect the area where the water reservoir sits on the machine. Look for any misalignment or improper positioning.
If you notice that the reservoir is not sitting correctly or is misaligned, readjust it to ensure proper placement.
Align the reservoir with the designated inlet and outlet on the machine. Make sure it sits securely and evenly.
Check for any obstructions or debris that may prevent the reservoir from fitting properly. Remove any obstacles if necessary.
Pay attention to the magnet attached to the reservoir or inside the machine. This magnet helps in detecting the water level. Ensure that the magnet is securely attached and properly aligned.
Once you have readjusted and aligned the reservoir correctly, carefully place it back onto the machine.
Ensure that the reservoir is fully seated and securely attached to the machine.
Plug in your Keurig and turn it on to see if the “Add Water” message has disappeared.

12. Refill the water reservoir tank with new water

If you are having trouble with your Keurig, try this troubleshooting guide.

Turn off the brewer and unplug it for a few minutes, then remove the water reservoir from the machine.
Plug your machine back in and wait a few minutes
Attach your water reservoir back to the machine and open and close the k-cup holder to make sure everything is working correctly.
Empty out any remaining water in the tank and refill it with fresh water until it’s full. There’s usually a max fill line located on the reservoir tank.
If there isn’t enough water, repeat this step until you have enough in there.
Make sure the exit needle is clean before running again. If they’re dirty or clogged up with coffee grounds then it could cause problems when trying to brew coffee again. Make sure those are cleaned out first thing before moving forward

13. Add water into the reservoir tank to the max line

If you are still dealing with issues, you can always fill the reservoir up again to the max fill line. If you are still dealing with issues, you may need to take the time to contact support and see if you can send your machine in for service or if they can talk you through some potential solutions for your machine.

In some situations, there is simply no simple solution to your problems, so you should take the time to really just try to get a technician to look at your machine so they can see if they can offer a better solution for both you and your machine.
