To cover this topic completely, we must refer to the noise produced by Nespresso coffee machines in good condition (without breakdowns), the noise produced by problems that appear over time, and the many uses of your machine.
How noisy can a Nespresso coffee machine be?
In a way, all coffee makers are noisy by nature, but pod coffee makers, especially Nespresso machines, are often branded as much noisier than other coffee makers. This bad reputation for Nespresso machines can be unfair since it is not so true that they make more noise than other pod coffee makers.
We have decided to prepare the following table so that you can compare the noise produced by 7 Nespresso coffee machines, both when preparing a coffee and when the pod is pierced when the machine reaches its maximum noise. The values contained in the table are measured in decibels (dB).
|Pixie||62 – 63 dB||80,7 dB|
|Creatista||57 – 58 dB||76,7 dB|
|Latissima||65 – 66 dB||75,4 dB|
|Citiz||58 – 59 dB||72,2 dB|
|Essenza||54 – 55 dB||70,7 dB|
|Vertuo||65 – 66 dB||66,6 dB|
|Maestria||59 – 60 dB||65,8 dB|
Based on the above information, it can be said that the noisiest coffee maker at the moment of piercing the coffee pod makers is the Pixie, coffee maker. It also ends up being one of the noisiest when preparing coffee.
Another of our conclusions is that the average maximum sound of these machines is between 72.6 dB and 60.5 dB while preparing a coffee. It should be taken into account that any sound can be considered annoying when it exceeds 55 dB; based on this, we can affirm that Nespresso coffee makers are noisy but just as noisy as other brands of machines.

Noisy parts of my Nespresso coffee machine
To begin analyzing the noise produced by my Nespresso coffee machine, it will be necessary to initially identify the parts that produce some sound while coffee is being prepared. Check if it has different components than other pod makers coffee makers and if these components are particularly noisy.
The water pump is the only component that produces sound directly in the Nespresso, as in any other coffee machine. However, other parts produce sound indirectly, such as the thermoblock, the pod injector or perforator, the machine casing, and the moving parts.
The sound produced by the vibrating pump of my Nespresso coffee machine
Also known as water pumps, coffee machines’ vibrating pumps are generally so-called because a piston inside the pump “vibrates” and causes the water to be propelled with sufficient pressure. Inside the pump, an electromagnetic field is generated, which produces this vibration, and as a consequence, the sound coming from the pump is tripled as follows:
- The electromagnetic field produces the sound (humming).
- The sound produced by the piston is hammering inside the pump.
- The combination of both produces the vibration of the pump.
In European Nespresso machines, the pump operates at 50 Hz frequency, 50 cycles per second. This differs from the American Nespresso machines, which operate at 60 Hz, 60 cycles per second. This refers to the number of times per second the piston moves (50 or 60).
To check if the excessive noise is coming from the water pump, you should pay attention to all the components that generate noise in the water pump, i.e., the electromagnetic field, the internal piston movement, and the general vibration of the pump.
If the pump’s operating conditions are optimal, it will produce little noise. But, some factors will cause the pump to emit a greater noise; among the main ones is the accumulation of lime inside the pump; if this happens, the noise will be louder when hitting and vibrating.
The sound produced by the thermoblock of my Nespresso coffee machine
The noise produced by the thermoblock is indirect, i.e., it only occurs when water circulates inside the machine at high pressure and temperature. The sound it emits is very similar to whistling, and it becomes more acute if the internal channels of the thermoblock are obstructed or if there is a leak.
The thermoblock in Nespresso coffee makers is located just behind the pod perforation channel; this means that if a sudden loud noise is produced when water is injected into the pod, it may be partly the responsibility of the thermoblock. But in general terms, it is very unlikely that the thermoblock produces the excessive noise of a Nespresso coffee machine.
The sound produced by the casing of my Nespresso coffee machine
The housing of the coffee maker will not produce any noise by itself, but when the vibrations of the water pump reach the outside of the machine, a noise will be heard in the machine. All the screws of the coffee maker must always remain very tight, as well as the small rubber bases at the bottom, as these retain the vibrations to a great extent.
The sound produced by the moving parts of my Nespresso coffee machine
In Nespresso coffee makers, three main parts can cause unwanted noises, which, in turn, are the most ignored; we are talking about the pod tray, drip tray, and water tank.
Suppose any of these parts is incorrectly positioned. In that case, the noise that the vibrations of the coffee machine can produce will be terrible, so make sure that they are always very secure and adjusted in place before starting the machine.
My Nespresso machine suddenly makes more noise.
All the information we have provided you in this article will help determine if your Nespresso coffee machine has become noisy; you can also help by comparing it with the table we prepared. And if the noise is louder than normal, you should investigate where the problem originates.
Start by disassembling the coffee maker so that you can discard the components of the machine that are most likely to produce noise, such as the moving parts and the housing. You will also be able to closely check the condition of other parts such as the water pump, the thermoblock, and other internal components.
When comparing the decibel values of your machine with the normal values, you can download any free application that allows you to make this measurement; this measurement doesn’t need to be extremely precise; a good approximation will suffice.
Decalcifying my Nespresso coffee machine reduces the noise it produces
The most probable cause of breakdowns in any coffee maker is the accumulation of lime scale and other residues inside the machine. This, in turn, also causes the noise of the coffee maker to be much louder.
You can corroborate this by measuring the decibels of the machine, with your measurement application, before descaling your coffee maker. Then perform the decalcification and measure again; the decibels will surely decrease.
