1. Mineral Build-up in the Machine

If you have used your Mr. Coffee maker for a while, mineral build-up may have occurred. 

The noise comes from the machine attempting to force water through the mineral build-up, causing it to vibrate and create a loud noise. This common issue can be fixed with a good descaling process. 

You can use a commercial descaler or a vinegar and water solution to remove the mineral deposits.

2. Grinding and Brewing Too Much:

A Mr. Coffee maker has a grinder and brew basket that work together to make your coffee. However, sometimes, when the machine grinds and brews too much coffee, it becomes overburdened, and the noise is heard. 

To fix this, you should check that the carafe is empty and there is no leftover coffee before brewing.

3. Clogged Water Liner:

A clogged water line is another reason your Mr. Coffee maker makes a loud noise. It’s also a common problem that occurs after a period of use. The noise comes from water attempting to pass through the clog. 

You must disassemble your Mr. Coffee maker and clean the water lines to fix this issue. If the clog is severe, consider replacing the affected part.

4. Faulty Heating Element:

If you have cleaned your coffee maker and the noise persists, you may need to check the heating element. 

Your Mr. Coffee maker makes a noise when the heating element malfunctions and it tries to draw more power for heating. If this is the issue, it would need a repair or replacement. Always seek professional help when dealing with the heating element.

5. Worn out Coffeemaker Parts:

Every coffee maker has a wearable part that gets worn out, and it is normal for these parts to make noise when worn out. 

It can be the grinding blades, pump motor, or drip mechanism. The best thing to do in this situation is to replace the affected part.

A loud coffee maker can be incredibly frustrating, but don’t panic! There are several potential causes for the noise and various solutions to quiet your machine down.

First, let’s diagnose the issue! Why is your Mr. Coffee maker making a loud noise? 

There are three main culprits: 

  • a dirty machine
  • a clogged water line
  • an old, worn-out motor

If your machine is making a gurgling or rumbling sound, then the problem is usually a clogged water line. 

Try cleaning out the machine and removing any hard water deposits that may be causing the blockage. An old motor that needs replacing could be the issue for a noisy machine with excessive vibration. 

Is it normal for my Mr. Coffee maker to be loud?

No, it is not normal for your Mr. Coffee maker to be loud. A new coffee maker should not make loud noises. 

However, over time and frequent use, the machine’s internal components can become worn, causing noise. 

Other factors contributing to a noisy Mr. Coffee maker include the quality of water used, mineral deposits in the coffee maker, and loose or broken parts.

What causes the loud noise in my Mr. Coffee maker?

Several things can cause loud noises in a Mr. Coffee maker. The most common culprit is mineral buildup. 

When water is heated and evaporates, it leaves behind mineral deposits. Over time, these mineral deposits can clog the machines’ internal components, leading to increased noise. 

This can be avoided by regularly cleaning your coffee maker with vinegar and water.

Can I reduce the noise of my Mr. Coffee maker?

Yes, you can do a few things to reduce the noise of your Mr. Coffee maker. 

  1. First, try cleaning it with vinegar and water. This should help remove any mineral deposits that may be causing the noise. 
  2. Secondly, check that all the parts are properly fitted and tightened. Loose or broken parts can cause unnecessary noises. 
  3. Thirdly, try using filtered water instead of tap water. The quality of water can affect the noise level of your coffee maker.

How do I fix a loud Mr. Coffee maker?

If the noise in your Mr. Coffee maker persists, it may be time to replace some of the machine’s internal components. 

You can contact the manufacturer or a professional technician who can replace the necessary parts. 

However, before this step, clean your coffee maker, tighten any loose parts, and try using filtered water to see if the noise reduces.


If your Mr. Coffee maker is making a loud noise, it’s usually an issue that can be easily resolved. 

Diagnosing the issue and implementing the necessary repairs can silence your machine and allow you to enjoy your coffee without a headache. 

Maintaining your machine with regular cleaning and checks can help prevent future noise issues and prolong the lifespan of your appliance. 

And if your machine eventually requires professional repair or replacement, remember that a good cup of coffee is worth the investment in a quality product that will serve you well for years.
