Why is my Keurig leaking? Complete Solution Guide!

Keurig coffee makers are a delightful blend of innovation that delivers efficiency and effectiveness. Keurig coffee makers are well known for producing consistent coffee day after day with the ease of just pushing a button. However, this does mean that Keurig is entirely problem-free.

Imagine you just wake up and craving that morning cup of coffee that energizes your entire day. You turn on your Keurig and start to brew like you always do. But you find that your beloved coffee machine is leaking. How frustrating! The machine can leak from the bottom or top from the pod holder making the machine dirty and even risk electrocution.

Many users encounter this problem and ask for a solution. So in this article, we will discuss the reasons behind Keurig machine leakage and remedies to fix them!

Why is Keurig leaking water from the top? Reasons and Solution.

There can be a few possible reasons why Keurig is leaking water from the top.

1)Overfilling the Water Reservoir

When you overfill the water tank, the Keurig starts leaking. Sometimes the water is filled above max fill in Keurig, which causes your brewer to leak. This is a common problem encountered when using Keurig k-MINI, commonly K-15 mini, in which the water tank is un-removable, and it is hard to judge the fill-up level (you should use a measuring cup and mug to add water).

Ensure not to overfill the water tank as it may cause several damages as pressure develop inside the tank and lacks space to escape. Sometimes you often need to fill the water to the brim so have enough coffee for your visitor.

However, remember that if water heats, it expands and ultimately leaks. Therefore it is necessary not to overfill the water rank to avoid any leakage. Use the manufacturer’s manual guide for instructions on filling the Keurig water reservoir to avoid any kind of leakage and spilling.


Another reason for leaking Keurig coffee machine is needle clogging. This occurs mostly due to stuck coffee ground and hot chocolate mix. Therefore it is necessary to clean the needles; otherwise, internal debris cause clogging of the needle and ultimately causes leakage from the Keurig machine.


The ultimate solution is to clean the needle regularly. We recommend you choose Keurig 2.0 cleaning kit because Cleaning is very much easy with this kit. Once you get to hold up this kit, all you need is to move the nozzle up and down five times in hot water.

Other methods include using a small paper clip, ceramic coffee mug, and clean water. Watch out the video for a complete guide.

3)Usage of Defective Capsules

Water leak from the top of the Keurig coffee machine is also due to defective capsules. If you are using a 3rd party capsule, reusable capsule, or another brand capsule that may not be fitting precisely in the pod chamber and ultimately leads to leakage.

 This capsule often possesses a thicker lid or alignment is off then, sometimes Keurig coffee maker finds it tough to penetrate needle.


The easiest solution is to use genuine coffee pods for your Keurig coffee machine and if the problem is still there, try to opt for other brands of coffee pods.

4)Broken or loose upper gasket.

Another reason for the Keurig machine leaking from the top is due to a broken or loose Gasket. The gasket is a part that is made of silicon that tightly holds the K-cup and water hose of the Keurig coffee machine.

The gasket seal on the puncture needle often gets broken, and ultimately, this dislocated gasket seal causes leakage in your Keurig coffee machine.


Ensure to align the gasket properly by closing any gap between the K-cup and the puncture needle to prevent topwater leakage.

Follow these simple steps for repairing the upper gasket.

  • Remove the water tank and tank lid from the machine by pulling them up and down.
  • Remove the three screws that secure the round screen to the bottom of the reservoir with the help of a screwdriver.
  • The circular screen has an O-shaped ring around it. Remove the rubber seal with a plastic opening tool and replace it with the new one.

If this doesn’t resolve the problem, contact Keurig’s official website to seek professional help.

5)Brewer is not holding K-cup Tightly.

Another reason for the Keurig coffee machine leaking from the top is that the brewer does not hold the k-cup too tightly. This should apply the needed hold to the K-cup inside. If the lid is loose or is not held too tightly, the pressure will build in the chamber and ultimately causing coffee grinds to get pushed into your cup.


 If this is happening, contact Keurig support to seek professional help.

6)Damaged check valve

A check valve is present on the bottom of the water reservoir of the Keurig coffee machine. When the water tank is pushed, there is a plunger that opens the check valve. After this, water is allowed to enter the machine from the water reservoir.

However, if this check valve is broken or damaged, this causes leakage of water from the top of the machine or from the bottom parts of the Keurig coffee machine. In this scenario, you need to replace the damaged valve with the new one to avoid leakage.


Usually, there are five main reasons behind the breakage of a check valve. If you can’t figure out the root cause, then it is highly recommended to disassemble the plastic on the side. Pour the water through it to identify the point of leakage.

It is more important to Identify the fault than to look for a solution for this cause. Try using hot glue or any other soldering tool to repair the check valve.

If the problem is still there, you can contact the Keurig customer representative team on their official website.

Keurig leaking from the bottom? Reasons and Solutions

It is easy to figure out the issues when Keurig is leaking water from the bottom. Remove and empty the water reservoir. Fill the water tank with fresh water and place it upright on top of a paper towel for a couple of hours. When you pick the water tank up, water issues are leaking from the bottom of the paper towel is damp.

1)Defective O-Ring

There might be a chance that the O-Ring that is responsible for establishing a secure connection between valves and pump gets defective or worn out.


The ultimate solution is to replace the old one with the new one because silicon grease won’t work here. You can simply order a new O – Ring from Keurig’s official website or from Amazon. However, you should be familiar with your brewer model because O –Rings differ per model.

If you find it difficult to replace it all by yourself, you can contact Keurig’s official website to seek professional help

2)Cracked water Reservoir

The water reservoir may have cracked or pinhole. It is quite easy to figure it out; all you need is to Flip the water tank over and look for any visible cracks. There might be a large crack or hairline crack responsible for leakage.


Depending upon the extent of the crack, you need to buy a new one or repair the older one. For repairs, you can use a dab of hot glue, or you can even solder the water tank.

If the water reservoir is non-repairable, then you can find a new one compatible with your model on Amazon.

However, it is highly recommended to replace the entire unit if you have resources to avoid any kind of frustration that may come with Keurig leaking from the bottom.

3)Water Reservoir worn seal.

There present a little valve at the bottom of the water Reservoir. When you securely connect the valve to the bottom of the water reservoir, water is supposed to exist from the valve into the brewer pump. Limestone buildup can interfere with this connection, unfortunately. You can see a seal on the valve, and water usually leaks from this seal.


Use a natural cleaner white vinegar solution to clean both the valve and base connection. Wipe it and put back the water reservoir to check any kind of leakage. You can also use silicone faucet grease for both parts.

To restore the seal, we recommend you choose Oatey Silicon Grease for restoring the seal. 

Coffee leakage from Keurig machine

While brewing K-cup, the needle inside the coffee machine makes two holes, one at the top and the other at the bottom. These two holes allow water to pass through the capsule and eventually make its way to your cup. There are possibilities that coffee beans get struck around the needle and eventually become harder. 

This situation usually occurs when you leave the K-cup pod in the holder for a longer period of time. As a result, the ground coffee builds up around the needle and prevents the needle from properly puncturing the pod. When that happens, coffee will get backed up in the brewing chamber. Instead of exiting the pod and heading for your cup, the machine starts to leak from the top.

Fault tube connector and worn out filters

Faulty tube connectors and worn-out filters are two primary reasons for coffee leakage in Keurig. A tube connector makes your coffee caffeine content higher than you set. On the other hand, if filters are worn out, coffee may leak.

The ultimate solution is to replace the old tube connector and filter with the new one. You can buy them locally from the retainable seller or from Amazon.

Dirty puncturing needle

A clogged Keurig machine might cause the bottom needle not to puncture correctly. The ultimate sign is the appearance of thin steam flowing from the coffee machine when brewing coffee. As a result, it causes excessive coffee flow to grind into your coffee mug. If you have noticed this, you need not panic; you can easily clean the exit needle.

Cleaning Dirty Keurig exists needle.

  • Turn off the machine, unplug the power cord and remove the water tank.
  • Grasp the K-Cup holder by the sides and remove it from the brewer by gently pulling it out.
  • Press the lever to display the exit needle, then hold it down while folding the stand. 
  • Carefully insert the straight end of the paper clip into the needle area and then move it in circles multiple times.
  • Rinse the K-cup holder with water and let it dry. With the help of a paperclip, clean the top of the needle.
  • Open the handle and look underneath to see the top entry needle.
  • Gently insert and wiggle the paper clip to clear it. Put the pod holder back in place and close the lid.

Cleaning Keurig Coffee Maker

Unless there are electrical issues or some broken parts, most of the issues you encounter in Keurig can be solved with proper Cleaning.

In other words, we can say that your Keurig needs to be descaled.

Water used for brew contains minerals. These minerals cause limescale to build up inside the Keurig machine. If this limescale remains untreated, ultimately they clog the Pathway of flowing water and can back up the water in the Keurig machine resulting in leakage. Additionally, clog also result in bad taste, affecting the temperature and even can make Keurig stop pumping water.

Therefore, Descaling is necessary to overcome all these issues. Coffee enthusiasts recommend descaling your Keurig once every 3 to 6 months if using a water filter. If you are using tap water, in which mineral content is high, then you need to descale your machine more often. The recommended time period is 1-2 months.

How to descale your Keurig Machine.

You should descale your Keurig machine more than once to remove the buildup that may be clogging your Keurig machine. You need to repeat descaling cycles more than once. It is highly recommended to use the manufacturer’s recommended descaling solution, or you can use natural cleaning solution like vinegar.
