My morning routine is incomplete without having a cup of coffee to kickstart the day. I remember how I set out one early morning to brew a coffee before hitting the road. When I noticed water pooling around the bottom of my Hamilton Beach coffee maker. 

It kind of disrupted my plan for the day because I had to take about 30 minutes to know why water was leaving from the bottom and fix it. So, if your Hamilton Beach coffee maker is leaking water from the bottom, read on to know how to fix it.

Why Is My Hamilton Beach Coffee Maker Leaking Water From The Bottom?

If your Hamilton Beach coffee maker is leaking water from the bottom, it could be because your filter basket is overflowing, your carafe is leaking, your water reservoir has some cracks, you overfilled your water reservoir or there is damage to the internal hoses in your coffee maker. Let’s walk through the troubleshooting steps!

Overflowing Filter Basket

As the coffee maker brews, you may see water spilling over the sides of the filter basket and collecting at the bottom. This occurs because you added too many coffee grounds.


  1. Measure your coffee grounds. Use the recommended coffee-to-water ratio specified in your user manual.
  2. Avoid overfilling the filter basket with coffee grounds.
  3. Check for any coffee grounds stuck in the filter basket that might obstruct the flow of water.
  4. Remove any debris to ensure water flows without obstruction.

Leaking Carafe 

If you notice water pooling beneath the carafe even when it’s not in use, inspect the carafe closely. A cracked carafe or a worn-out lid seal could be the cause.


  1. Carefully examine the carafe for any visible cracks, chips, or damage.
  2. Pay close attention to the area where the carafe meets the lid.
  3. Check the seal on the lid for signs of wear, misalignment, or damage.
  4. Make sure it forms a tight seal when the lid is closed.
  5. If you find any damage to the carafe or lid, it’s best to replace the affected part.

Damaged Water Reservoir

If there is a  crack on the side of the water reservoir. When you fill it with water, you’ll see that water seeps out from the crack, causing a leak onto your countertop.


  1. Examine the water reservoir carefully for any visible cracks, chips, or other damage.
  2. If you notice a small crack, stop using it immediately to prevent further leaks. Order for a replacement reservoir.
  3. Feel free to contact Hamilton Beach customer support for information on how to get a replacement.

Overfilling The Water Reservoir 

Pouring more water into the reservoir than it can hold will result in overflow and water leaking from the coffee maker. 

Let’s say the water reservoir of your Hamilton Beach coffee maker has a maximum fill line marked at 10 cups. If you fill it with 12 cups of water, you’re likely to experience leakage as the excess water has no place to go except to spill out.


  1. Always follow the recommended water capacity specified in your user manual. Do not exceed the maximum fill line.

Internal Hose Damage

During the brewing cycle, you may notice water leaking from the bottom of the coffee maker, but there are no visible external issues. It might be that an internal hose has a crack

Over time, hoses or tubes inside the Hamilton Beach coffee maker can develop cracks, become brittle, or experience wear and tear. When these happen,  water can escape from the damaged areas.


  1. Inspect the internal hoses for any visible cracks, holes, or damage.
  2. If you find damaged hoses,  it’s best to contact Hamilton Beach customer support for professional repair or replacement options.

How Do I Stop My Hamilton Beach Coffee Maker From Leaking?

Follow these troubleshooting steps to fix your Hamilton Beach Coffee Maker that Is leaking:

Gather the Required Tools

You’ll need a tri-wing screwdriver (size Y1) or a standard Phillips-head screwdriver.

Unplug the Coffee Maker

Make sure that the coffee maker is unplugged, and let it cool down completely before starting any disassembly.

Access the Screws

Turn the Hamilton Beach coffee maker upside down onto a soft cloth or towel to protect the surface.

Start by looking at the bottom of your Hamilton machine. There are eight special screws there, and one of them is important because it’s connected to the back panel in the middle. Remove these screws.

Detach the Bottom Plate

To access what’s inside, I recommend you take off the entire bottom part of the machine.

Gently lift or pry off the bottom plate. Take care not to use excessive force, as it may lead to damage.

Inspect the Interior

With the bottom plate removed, you can now access the internal components of the coffee maker.

Next, you’ll need to pull the sides of the coffee maker away from the back panel. There are little tabs you can press with a flathead tool to help you do this.

Once the sides are pulled away, you’ll see five screws you need to remove. Two are at the bottom, two at the top, and one is hidden below a cover near the top.

Be careful when removing the last screw because there are delicate plastic tabs nearby.

Fix The Problem

After removing all the screws, you’ll be able to see the problem. If the hose that carries hot water to the top of the coffee machine isn’t connected properly, a metal clamp won’t work well.

To fix this, you can use a zip tie along with a more secure ½-inch hose clamp.

Reassemble the Hamilton Beach Coffee Maker

After resolving the issue, reassemble the coffee maker in the reverse order of disassembly. Make sure that all screws are securely tightened but not over-tightened to prevent damage.

Test the Coffee Maker

Plug in the coffee maker and perform a test with water only (no coffee grounds) to confirm that the issue has been successfully resolved.


Why Is My Hamilton Beach Coffee Maker Not Pumping All The Water?

If your Hamilton Beach coffee maker is not pumping all the water, it’s possibly because it is clogged with mineral deposits. You should descale it to remove the mineral deposits. If that doesn’t fix the issue, you can take apart the coffee machine to check if you can remove and clean the filter more thoroughly.

Why Does My Hamilton Beach Coffee Maker Overflow?

Your Hamilton Beach coffee maker is overflowing because the paper filter has crumpled inside the basket or you used very finely ground coffee.
Make sure that you’ve put the coffee filter and the pot in the right place, and that you’ve used the right amount of coffee.


A Hamilton Beach coffee maker leaking water from the bottom can disrupt your morning routine. But by following these troubleshooting steps, you can resolve the issue and continue enjoying your daily cup of coffee. If you can’t handle some of the delicate parts of your coffee maker as detailed in this guide, please contact a repair technician to help.
