You might have noticed some strange gurgling sounds coming from your coffee maker. It can be a bit surprising if you’re not used to it. These sounds are usually normal and happen when your coffee maker is working its magic. In this blog post, we’ll explore why your coffee maker makes these noises and if there’s anything you need to do about it. So, let’s dive in and see what’s causing that gurgling sound!
Common Causes of Gurgling Sounds from Your Coffee Maker
Air Pockets
One main reason your coffee maker might gurgle is air pockets. When you first start brewing coffee, air can get trapped inside the machine. These air pockets can cause bubbling and gurgling noises as the water heats up and tries to push through them. It’s like when you blow air into a straw, and bubbles form. To fix this, try running a cycle with just water and no coffee grounds. This can help get rid of the air pockets.
Hard Water Buildup
Another reason for gurgling sounds is hard water buildup. Hard water has minerals that can settle inside your coffee maker over time. This buildup can block the flow of water and make the machine work harder, causing strange sounds. You can clean this buildup by running a mixture of vinegar and water through the coffee maker. Just make sure to rinse it well with clean water afterward to remove any vinegar taste.
Clogged Filter
A clogged filter can also make your coffee maker gurgle. If the filter gets clogged with coffee grounds or oils, it can block the water flow. This can create pressure and result in gurgling noises. To fix this, check the filter and clean or replace it if needed. Also, make sure you are using the right type of filter for your coffee maker.
Faulty Parts
Sometimes, gurgling sounds come from faulty parts. If a part of your coffee maker is damaged or not working correctly, it can cause unusual noises. If you’ve tried cleaning and checking the filter but still hear gurgling, it might be a good idea to have a professional check your coffee maker for any broken parts.
By understanding these common causes, you can better maintain your coffee maker and enjoy your coffee without any annoying gurgling sounds.
How to Fix Gurgling Sounds from Your Coffee Maker: Steps Guide

1. Run a Clean Cycle
To fix the gurgling sound from your coffee maker, start by running a clean cycle. This is an easy and effective way to remove any air pockets or mineral buildup inside the machine. Begin by filling the water reservoir with a mixture of equal parts water and white vinegar.
The vinegar helps to break down any deposits that might be causing the gurgling noise. Once the reservoir is filled, turn on the coffee maker and let it run a full brewing cycle just like you would if you were making coffee. The vinegar solution will flow through the machine, cleaning out any buildup.
After the cycle is complete, it’s important to rinse out the vinegar. To do this, fill the reservoir with clean water and run a couple of cycles with just water. This will help remove any leftover vinegar and ensure your coffee maker is ready for your next brew. If the gurgling sound persists, you may need to repeat the cleaning process. Regularly running a clean cycle every few months can help keep your coffee maker in good condition and prevent future gurgling issues.
2. Check and Clean the Filter
Another common cause of gurgling sounds in your coffee maker is a clogged or dirty filter. To fix this, start by removing the filter from your coffee maker. Take it out carefully, making sure not to spill any coffee grounds.
Wash the filter with warm, soapy water. Use a brush or sponge to scrub away any coffee oils or grounds that may have built up. Rinse the filter thoroughly with clean water to ensure no soap residue remains.
If your filter is old or damaged, it’s a good idea to replace it with a new one. An old filter may not fit properly or could be clogged beyond cleaning. When placing the new or cleaned filter back into the coffee maker, make sure it fits securely and is properly aligned.
A properly placed filter will help ensure smooth water flow and reduce the chances of gurgling noises. Regularly checking and cleaning your filter can help keep your coffee maker running smoothly.
3. Descale the Coffee Maker
Descaling your coffee maker is another important step in fixing gurgling sounds. Hard water can cause mineral deposits to build up inside the machine, which may lead to gurgling noises.
To descale your coffee maker, use a descaling solution or a mixture of white vinegar and water. Pour the solution into the water reservoir, filling it according to the instructions on the descaling product or a 50/50 mix of vinegar and water if using vinegar.
Turn on the coffee maker and let it run a full brewing cycle with the descaling solution. This helps to break down any mineral buildup inside the machine. After the cycle is complete, fill the reservoir with clean water and run several cycles to rinse out any remaining descaling solution or vinegar.
This step is crucial to ensure that no vinegar taste is left in your coffee maker. Descaling your coffee maker regularly, especially if you have hard water, can help prevent gurgling sounds and keep your machine in good working order.
4. Ensure Proper Assembly
Sometimes, gurgling sounds can be caused by parts of the coffee maker not being assembled correctly. To check this, make sure all parts are in their proper places. Start by checking the water reservoir to ensure it is securely attached.
Next, check the filter basket and any other removable parts to make sure they are correctly aligned and not loose. Misaligned or loose parts can interfere with the water flow and cause gurgling noises.
If you find any parts that are not properly fitted, adjust them as needed. Ensure that all parts click into place or are securely fastened. If you are unsure how to reassemble your coffee maker, refer to the user manual for instructions.
Proper assembly helps to ensure smooth operation and reduces the chances of gurgling. If the coffee maker still makes noise after checking the assembly, there might be another issue at play, such as a faulty part that may require professional repair.
Inspect for Faulty Parts
If the gurgling persists after cleaning and checking the filter, inspect your coffee maker for any faulty parts. Look for signs of wear or damage. If you find any issues or if the machine is still making strange noises, consider contacting a professional repair service or the manufacturer for help.
By following these steps, you can fix the gurgling sounds and get your coffee maker back to brewing your favorite coffee quietly.
Question in Your Mind
Is it safe to use tap water in my coffee maker?
Yes, it is generally safe to use tap water in your coffee maker. However, if your tap water is hard or has a lot of minerals, it can lead to buildup inside the machine. Using filtered or bottled water can help prevent this issue.
Can I use other cleaning solutions besides vinegar?
