6 Reasons: Why Is My Coffee Maker So Loud? With Fixes

You wake up early, walk to your kitchen, and brew your first cup of coffee. As you press the button on your coffee maker, it starts making a strange noise. It’s a common situation for many coffee lovers. 

If you don’t know why your coffee maker is so loud, you might think something is wrong with it. 

In this blog, I will explore six reasons why your coffee maker is so loud and what can be done to fix it.

Common Reasons Why Is Your Coffee Maker So Loud

Why Is My Coffee Maker So Loud?

1. Mineral Build-Up

The mineral build-up is the most common reason your coffee maker is loud. When you use hard water to brew coffee, calcium, and other minerals build up inside your coffee maker. 

Over time, these deposits can clog the machine’s pipes and cause it to make more noise. 

Solution: To fix this issue, descale your coffee maker with vinegar or a specialized descaling solution regularly.

2. Worn Out Gasket

The gasket is a rubber ring that seals the coffee maker’s various parts. With time, these gaskets can become worn out and dried, causing them to crack or degrade. 

Solution: If your coffee maker is old and making loud noises, it may be time to replace the gasket. In many cases, a simple replacement can eliminate the noise.

3. Cracked Water Reservoir

The water reservoir is an essential part of a coffee maker. If it cracks or has a leak, it can start making loud, gurgling sounds. 

You can usually determine whether the reservoir has a crack by looking for water dripping at the bottom of the machine

Solution: To fix this, purchase a new water reservoir or contact the manufacturer for replacement.

4. Loose or Broken Parts

When your coffee maker is operational, it vibrates. This vibration can lead to loose or broken parts like screws and bolts. 

Solution: Check for loose or broken parts if you hear loud clicks and rattles. Tighten any screws or replace any broken parts to reduce the noise.

5. Coffee Grinding

Some coffee makers have a built-in grinder responsible for grinding your coffee beans. The grinding process creates loud noises; some machines are noisier than others. 

Solution: If your coffee maker has a grinder, try cleaning it to reduce the noise. If the noise persists, consider using pre-ground coffee instead.

6. Poor Quality Motor

Lastly, some coffee makers are inherently loud due to poor-quality motors. Low-quality motors often generate more noise than higher-end models. 

Solution: If your coffee maker is noisy from day one, and you’ve tried all the above fixes, it may be time to replace it with a better-quality model.

Why is my Cuisinart coffee maker so loud?

The main reason behind your Cuisinart coffee maker’s noise is usually the heating element. The heating element can cause a popping or clicking noise as it heats up to generate steam to make your coffee. 

This noise is normal, but if it’s too loud or occurs too often, you may need to thoroughly check and clean your machine’s heating element. 

Beyond this, Cuisinart coffee makers are generally known to be quiet machines, so if you’re still experiencing noise issues, it may be time to replace your machine.

Why is my Bunn coffee maker so loud?

Bunn coffee makers can be one of the loudest models due to their design and brewing process. Bunn coffee makers are built with a commercial-grade heating element that brews coffee fast, resulting in a loud noise. 

The sound occurs when a spray head forces water against the ground coffee beans. If you notice strange noises outside the initial brewing period, you may need to check your spray head or thoroughly clean the coffee maker.

Why is my Ninja coffee maker so loud?

Ninja coffee makers are known for their powerful brewing system that extracts coffee flavors but can be quite loud. 

The sound may occur when you’re getting your coffee machine ready to brew, during the brewing process, or during the cleaning cycle. 

If you’re aware of the source of the sound, it may be due to the brewing process or the machine’s cleaning cycle. If the sound comes from outside of these actions, we recommend contacting the manufacturer directly for tips to fix the issue.

Why is my coffee machine so loud?

If your coffee machine sounds like it’s angrily chewing up the coffee beans, there may be several things to look out for. 

  • First, the machine’s steam valves may need to be cleaned, which can cause hissing sounds. 
  • Second, your machine’s pump might malfunction, causing it to be louder than usual. 
  • Finally, if you have yet to clean your machine deep regularly, this may also be why it’s making strange noises. 
  • Be sure to follow the manufacturer’s cleaning instructions thoroughly.

Why is my coffee maker making a popping noise?

When your coffee maker makes popping sounds, it might be because of the mineral buildup in your machine. 

If you cannot clean the machine with vinegar or the manufacturer’s recommended special formula, it’s often best to replace it. 

Mineral buildup can impact the performance and lifespan of your coffee maker, and it’s not something you want to overlook.


Now that you know some of the reasons behind a loud coffee maker, you can take necessary measures to reduce the noise or address specific problems related to your machine. 

Keeping a clean and well-maintained coffee machine will help prolong its lifespan and keep it running quietly. Remember, the key to quiet mornings is often a well-functioning coffee maker!

Regular cleaning, replacing worn-out parts, and purchasing a higher-quality machine are good options for reducing noise. 

I hope this guide has helped troubleshoot your coffee makers’ noises, allowing you to enjoy your coffee in peace.
