Not again!

Your Cuisinart coffee maker is leaking from the bottom. Well, a problem like this can be very annoying and even ruin your day.


Obviously, you want to know what causes leakages in your coffee maker and how you can prevent subsequent ones.


You’ve come to the right source. Here’s everything you need to know.

Leaking Cuisinart Coffee Maker

If you have a leaking Cuisinart Coffee Maker, these fixes can help. Ensure you use only Cuisinart GTC filters. And avoid overfilling the reservoir or adding excessive coffee beans. Clean the coffee maker with vinegar solution. Also, fix the pump valve and water hose. Other fixes include changing a bad carafe, its lid, and the brewing switch.

1. Use only Cuisinart Gold Tone Coffee Filter

Cuisinart Gold Tone Coffee Filter

Get this:

Using low-quality coffee filters is one reason your coffee might be overflowing. Here, a leak can be a result of poorly-design filters or a bad fit.


This brand recommends that you only use the Cuisinart Gold Tone Coffee Filter.

2. Don’t Overfill the Water Reservoir

Cuisinart Water Reservoir

This is a fact:

Putting too much water in your Cuisinart coffee maker’s reservoir can cause leakage.

However, this is easily preventable as there is a maximum capacity marker on the water reservoir.

So, to avoid a leak, don’t fill the water reservoir past the max line.

Yes! It’s that simple.

3. Avoid Adding Too Much Coffee Beans

Of course:

Too many coffee beans in the grinder can clog it and cause an overflow.

More so:

According to the Cuisinart Instruction Booklet, the adequate amount of coffee beans in a cup is 14 tablespoons.

4. Clean Your Cuisinart Coffee Maker with Vinegar Solution

Over time:

As you use your Cuisinart Coffee Maker, it can accumulate debris from mineral deposits and coffee beans.

In turn, this accumulation can clog the entire system of the coffee maker resulting in a leak.

In addition:

The debris makes your coffee maker unhygienic, which is obviously bad for your health.


It is imperative that you clean your coffee maker regularly using a vinegar solution. You can read about the adequate quantity of white vinegar and water in the instruction booklet.


Pour the solution inside the coffee pot and turn on the coffeemaker. Watch as the solution cleans and unclogs the pumps in a matter of minutes.


Wipe debris and stains from the brew basket, grinder, and machine reservoir using a clean fabric dipped into the solution.

Don’t forget this:

After cleaning the coffee maker with a vinegar solution, the next brewing cycles you run should be without coffee.


Running a coffeeless brewing cycle thoroughly rids the machine of any hidden debris that could cause future leakages.

It also rinses off the smell of the vinegar from the machine.

5. Unclog Faulty Pump Valve

If the pump valve of your Cuisinart coffee maker is clogged, it will hinder the flow of water.

As a result:

The water level remains low and can’t pass freely through the fill tube. Consequently, causing a leak.

So, how do you fix a faulty pump valve?

Well, you can try unclogging the valve. Coffee grounds and mineral deposits are the most common causes of clogged pump valves.


Rid the valve path of the remains of coffee beans and mineral deposits by flushing it.


You can always seek professional help if the valve pump is sealed.

6. Fix or Replace Defective Water Hose

In case you don’t know:

The water hose in a coffee maker is located at the bottom. It serves as the connection between the water tank and the machine’s heating unit.       

Over time, this water hose may become loose due to metal tubing corrosion.

To fix this: 

Just tighten the hose clamp when you find it loose, and that solves this seemingly complex problem.


If the water hose is damaged due to overheating, you will need a replacement.

To know if the water hose is damaged, unplug the coffee maker, turn it upside down and remove the screws.

After that, check the hose pipe for tears on its outer rubber. A tear may warrant replacement.

7. Replace the Damaged Glass Carafe and Loose Lid

As expected:

A damaged/broken glass carafe will most likely result in a leak. In the same way, if the handle on the carafe is damaged or loose, it might leak.

The good thing is:

You can always replace a damaged carafe with a new one.

Like other components of the Cuisinart coffee maker, carafes are available on most eCommerce platforms.


If the leak is due to a loose handle, simply ensure that it is properly tightened to the carafe.


Check if the lid seals properly.

Obviously, loose lids can cause water or coffee leaks. Therefore, if you seal the lid over and over again and the leaking persists, you should get a new one.

  1. My cuisinart coffee maker’s red cleaning light will not go off. I have followed the cleaning instructions very carefully several times. Clearly the clean function does not work.

    • You typically need to disassemble part of the unit to access the valve. However, before you proceed, ensure that the coffee maker is unplugged and cooled down to avoid any risk of electric shock or burns.

    • Hi Ken. Have your coffee maker’s model number (SS-15) and possibly the serial number ready. This information will help them identify the exact part you need. Try to find on Ebay or reach out to Cuisinart’s customer support.

      • Your 4 cup coffee maker carafe dribbles when pouring due to poor seal between metal and plastic, really poor design and quality
