Last Updated on January 11, 2023 by Jorian

Is your Breville Espresso Machine making a loud noise when grinding or brewing? This is a common issue with the Breville Barista Express, Touch, Pro, The Bambino, and even The Oracle machines.

In this article, we’ll uncover the possible causes and provide solutions to fix the problem and restore your peace and quiet while enjoying your coffee.

Why Is My Breville Espresso Machine Making Loud Noise?

A loud noise from a Breville Espresso Machine can be caused by a number of issues, such as a problem with the grinder, worn-out parts, or a clogged or dirty machine. It may also be due to the build-up of mineral deposits inside the machine. Let’s get into some more detail below.

Breville Grinder Making Loud Noise

The first thing you want to try if the grinder makes a weird noise is to clean the entire grinder from the inside. Because coffee beans and ground coffee can get stuck there, causing the noise.

How To Clean The Coffee Grinder

Not only can cleaning the coffee grinder stop it from making noises it isn’t supposed to make. By cleaning the grinder regularly you’re making sure that it always works properly. Cleaning the grinder regularly also prevents it from breaking and makes it last a little longer. Especially if you use flavored or moist coffee beans.

Unplug And Remove The Container

To begin, unplug the espresso machine and remove the coffee container that sits on top of the grinder. Remove the cap from the container and turn the little handle inside the bean reservoir to the left to take it off.

Vacuum The Coffee Beans Out

After you remove the container, you can see the grinder inside. There are probably some coffee beans left in it. You can vacuum those out.

Then take the metal pin and turn it counterclockwise to get the top part of the grinder out. You can clean this part with a brush.

Remove The Hexagon Bold

Underneath this part, you will see a hexagonal socket head. It’s counterintuitive, but turn this socket to the right to loosen it. Then you can get the bolt out and there are some washers on it. Make sure you remember what order it’s placed in. Then you can take out another grinding part and clean that with a brush.

When you put the part with the hexagon socket back, make sure that you don’t tighten it too firmly. Once the grinder starts spinning with it and you can’t screw it any tighter give it a little wack and it should be good.

Then there is a lot of ground coffee in the machine again. You can also vacuum this out with the vacuum cleaner. 

Remove The Wheel

Then you’ll see a wheel down there. You can lift that up with a pair of pliers. You don’t have to unscrew it or anything. It just comes up when you pull it. You can also clean that part with a brush.

Remove The Cloth Ring

At the bottom is a small fabric ring. Take the fabric ring out. Make sure the small cloth washers are still intact, these are known for breaking fast. If they break, it can cause fretting between grinding parts, which can also lead to more noise.

Now there is nothing on the bottom except more ground coffee. You may also vacuum this out.

There is a hole in the bottom where the ground coffee goes through to the portafilter. Coffee can get stuck down there. Make sure to unjam this hole with something like a toothpick or screwdriver.

Put Grinder Back Together

Put the grinder back together in reverse order and it should be good to go again.

The Roast of The Beans Is Too Light Or Flavored

If after you’ve cleaned the grinder and made sure that all the parts are intact but the grinder is still making noise. It could be that you are using a coffee bean that is roasted too lightly or that is flavored.

A good metaphor might be to compare it to bread. Fresh (Moist) bread you have to tear, but old (dry) bread you can break in half.

It’s the same with coffee beans. Darker roast beans have less water stored in making it easier for the grinder to grind fine. The grinder likes snapping but can’t tear very well. I hope that made sense.

Flavored beans stick to the grinder more easily, causing it to get jammed and not work properly.

The Last Thing You Could Try

If the above solutions didn’t work, there is probably something wrong with the motor or other parts inside the machine.

Unless you are very handy with fixing appliances, your best shot is to contact Breville customer support. If you’re still under warranty they will repair your espresso machine for free or even send you a new one!

Make Sure There Is Water In The Tank

This one is pretty self-explanatory, but make sure that the water reservoir has enough water in it. when the Breville can’t draw water it will suck up air causing a weird noise.

Noise is not the only reason why you should avoid pressing the brew button without water in the tank. Because this can also cause air bubbles to get stuck in the tubes, which can make the espresso pour inconsistent or even clog your machine.

The Breville Espresso Machine Needs Cleaning And Descaling

Breville espresso machines start to sound a bit different when there is a lot of mineral buildup in the heating component and tubes. There can be one small scale causing all the buzzing noise. What you want to do in this case is clean and descale your Breville.

Cleaning Cycle On The Breville Espresso Machine

Take out the portafilter, and put the one-cup basket and the cleaning disk in. Get a cleaning tablet and place it in the center of the portafilter. Then reinstall the portafilter.

Make sure to not use the branded Breville cleaning tablets. They are way more expensive than some generic cleaning tablets that do exactly the same. These third-party cleaning tablets work perfectly for me.

Place a large container under the portafilter. Then press and hold the one-cup, two-cup, and power buttons for 10 seconds until the cleaning cycle begins.

Wait until it’s finished, and then move on to de descaling cycle.

Descaling Cycle On The Breville Espresso Machine

Before you start the descaling process it’s important to know that you cannot use white vinegar to descale your Breville espresso machine, this will damage the machine.

What you need to use is a descaling solution. Again, make sure to not use the branded Breville solution. They are way more expensive than a non-branded descaling solution. I always use this descaling solution for my machine.

Once you have the descaling solution, you want to follow the instructions on the bottle to dissolve it in the water tank. I usually use a one-to-one ratio of solution to water.

Then you need to turn your machine off, hold the two-cup button and the power button for 5 seconds. Then some lights will start flashing and you’re in descaling mode.

Now that you’re in descaling mode you first need to hold the one-cup button for 25 seconds so the water can run through the portafilter.

Then turn the hot water on for 10 seconds and finally turn the steamer on for 15 seconds. Repeat the cycle until the water tank is empty. Once the tank is empty, you can turn it off.

When you turn your Breville back on again the clean me descaling light should be off.


Loud noise from a Breville Espresso Machine can be caused by a variety of issues, from a problem with the grinder to a build-up of mineral deposits inside the machine.

By understanding the possible causes, and implementing some of the solutions provided in this article, you will be able to solve the issue and enjoy your coffee in peace and quiet once again.

Remember regular cleaning and descaling of your machine will ensure a longer lifespan of the machine and also noise-free operation. And If you still have troubles, don’t hesitate to contact Breville support.
