Picture this:

You fill the water reservoir of your Keurig coffee maker only to watch as water trickles out from underneath grimly. You are frustrated because you now have a mess to clean up, and you wonder why your once reliable Keurig has failed you.


If this sounds like a problem you’re facing, then the stars have aligned, and you’re in the right place. You are probably trying to figure out the cause of your leaking Keurig and how to fix this massive inconvenience.


We have conducted extensive research and compiled the answers you seek in this article. Here’s what to do when your Keurig is leaking from the bottom.

Keurig Is Leaking From the Bottom

For whatever reason, your Keurig is leaking from the bottom; there are several methods to solve this problem effectively. You should pay attention to overfilling the water reservoir, replace a cracked tank or faulty water hose, unclog and descale your machine, clear the valve pump, or change a damaged O-Ring.

1. Avoid Overfilling the Water Reservoir

Get this:

Overfilling your Keurig’s water reservoir is the most common and easily correctable cause of a leaking Keurig. People often eventually lose regard for the capacity marker and begin to freestyle the amount of water they add to the tank.

In essence:

To avoid a leak, ensure that you don’t add water past the max fill line of your Keurig’s water reservoir.


It would help if you paid attention to the alignment of your water reservoir to avoid flooding the system.


Mindfulness could be the only solution you need to keep your Keurig from leaking.

2. Replace the Cracked Water Reservoir

Here’s the thing:

If your Keurig is leaking from the bottom, then it is likely that the water reservoir is cracked. You can check for cracks by filling your tank, holding it over the sink, and watching for drips.

The brewer may have fallen or developed hairline cracks due to age and environmental factors.


If the cracks are extensive and cannot be repaired, the immediate solution is to replace the water reservoir. Otherwise, you can apply a spot of hot glue to the affected areas to repair the tank.


We highly recommend outrightly changing the tank for a more long-lasting remedy. Once the water tank is crack-free, your Keurig will also be leak-free.

3. Replace or Tighten the Faulty Water Hose


The water hose is located at the bottom of your Keurig and leads to leakage when faulty. It could either be loosely attached, weakened, or damaged by perpetual heat exposure.


If the water hose is impaired, you would be required to replace it with a new, functional one from Keurig or an online store.

In addition:

When it is loosely attached, you will need to unscrew the base of the machine and fasten the hose more tightly.


Ensure that your Keurig is powered down and unplugged before opening the base, as water and exposed electricity do not combine nicely.

After replacing or tightening your water hose, your Keurig should run effectively without leakage.

4. Descale and Unclog Your Keurig Coffee Maker

A buildup of mineral deposits (limescale) will clog your Keurig coffee maker and lead to leaks and other malfunctions.

As such:

Descaling and unclogging your Keurig when due is necessary to avoid this malfunction.

Here’s what to do:

Fill your Keurig’s water reservoir with equal parts of the descaling solution or white vinegar and water. You should place a large cup on the drip tray and run a brewing cycle until the cup is full.


Let the descaling solution soak in the reservoir for a while to break down mineral compounds. You can then pour out the solution and run several rinse cycles with plain water to get rid of debris.

After this:

Your Keurig should be as good as new, and you would have successfully terminated its leakage. Good job!

5. Clear the Valve Pump

Clear the Valve Pump Keurig

You see:

Your Keurig’s valve pump is responsible for transporting water from the reservoir to the machine. When it is clogged with mineral deposits or ground coffee, the water flow will be hindered, often resulting in a leak.


It would be best to immediately attempt to clear and unclog the valve pump to restore your Keurig to its peak state. You could hire a trained technician for this job in the event of a sealed valve pump.


If the valve pump is detachable, you should be able to unclog it and reassemble your Keurig.


You can reach out to Keurig customer support for assistance, and your Keurig will work fine in no time.

6. Replace the Damaged or Misplaced O-Ring

Get this:

Your Keurig might leak from underneath because of a damaged or misplaced O-Ring.


The O-Ring is a small silicone band that seals the bottom of the water reservoir connecting the tank to the water hose.


When dealing with a leaking Keurig, you should check that your Keurig’s O-Ring is still in place and also check for damage. An obvious solution would be to replace the defective or lost O-Ring with a new one from Keurig.

One more thing:

You must take note of your Keurig model because O-Rings are model specific. Don’t hesitate to contact customer support for assistance with replacing your O-Ring.
