The Most Common Problems Faced By Nespresso U Owners

Unsurprisingly, the Nespresso U coffee maker has captured the affection of coffee enthusiasts worldwide with its stylish design and simple-to-use features. But while some users are happy with this machine, some have also experienced common problems, just like me. And here, I will talk about the common problems I have encountered with my Nespresso U coffee machine. Scroll down to check them out.

Leakage: One of the most common problems I have faced with my Nespresso U is the leakage issue. And Some users have also reported that their Nespresso U machines are leaking water or coffee from the machine or the capsule holder and how they are dealing with a messy cleanup at the moment when they are anticipating a delicious cup of joy.
Capsule Ejection Failure: Another issue is that when the user inserts a capsule, it gets stuck there, and after preparing a coffee, when they want to eject the capsule to add a new one and prepare their next cup, the capsule fails to eject, leaving them hopeless with the blocked machine.
Pump Failure: One of the most frustrating problems is when the Nespresso U refuse to pump water while brewing; in short, the pump system stops working. This pump failure can be a major setback for the day when they end up surviving a day without their caffeine fix.
Descaling Issue: Descaling is a crucial maintenance process for Nespresso machines, including Nespresso U. Sometimes users do not correctly execute the descaling process, which may result in problems such as developing mineral scales which can cause blockages and affect the heating element. This blockage also affects the coffee flow, and the users wait for the coffee to flow out of the outlet.
Noisy Operation: Some users have reported that their Nespresso U make loud noises while operating, which is quite disturbing for the users and interrupts the brewing pleasure.

It is important to note that not all Nespresso U owners will experience these problems. Many users have reported being happy with their machines and encountering no significant issues.

I was experiencing problems with my Nespresso U machine, so why not write down the solutions for people facing these problems with their Nespresso U machine? So, let’s find out how to troubleshoot and solve the problems of Nespresso U and resume coffee brewing!

Problem 1: Why Is There No Light On The Buttons Of My Nespresso U?

The most satisfying thought in the morning is having your Nespresso U coffee machine on the kitchen top preparing a perfect cup of coffee, but the absence of light on the buttons may make you anxious. The satisfaction vanishes in seconds, and disturbing thoughts set in; you start wondering why there is no light on the buttons of your Nespresso U coffee maker. What’s wrong with it? Calm down; I am here to help you troubleshoot this problem. Let’s figure out why there is no light on the buttons of your Nespresso U and how you can light up the buttons again.

Cause1: Nespresso In Automatic Off Mode

You are not observing the light on the Buttons of your Nespresso U because your machine is switched off due to the Automatic off mode. The automatic off mode turns off the coffee maker when not used for more than nine minutes. The default setting for auto-off is nine minutes.

How To Fix It: Touch Any Of The Button

To get your coffee maker back to operating mode, touch any of the Buttons or push the slider of your Nespresso U.

Cause 2: Dysfunctional Power Outlet

There is no light on the Buttons of your Nespresso U because the power outlet is non-functional, which means there is no power supply in this outlet. Your coffee machine is not receiving the electricity required to turn it on and start working.

How To Fix It: Check The Power Outlet

If the outlet is non-functional, connect your machine to some other outlet at your place.

Cause3: Loose Connection

You have not correctly plugged the switch into the outlet, which causes a loose connection and results in an inconsistent power supply to the machine.

How To Fix It: Plugin The Switch Properly

Reconnect the power cable firmly to ensure your machine gets the right power supply to operate.

Cause4: Voltage Difference

The power outlet’s voltage supply is different from the machine’s. If the voltage supply at the power outlet and the voltage inside the machine are unequal, the machine’s internal voltages may become unstable. As a result, your machine won’t start.

How To Fix It: Ensure The Voltage Compatibility

Ensure the voltage supply is appropriate for your machine.

Cause 5: Blown Fuse

The Buttons are not illuminating, maybe because the fuse is blown.

How To Fix It: Check The Fuse

You need to check the fuse, and if it has blown out, replace it. But don’t do it on your own; consult a professional.

Problem 2: Why Is No Coffee, No Water Coming Out Of My Nespresso U?

Are you trying to operate your Nespresso U so you can brew a delicious coffee? But nothing is coming out of the coffee outlet, and you feel helpless about this issue. Ugh-Oh, It’s a matter of concern. If you are wondering why there is no coffee or water coming out of your Nespresso U, then I have the answers for you. I will walk you through the causes and solutions to this problem. Let’s dive into this problem and get you back to sipping your caffeine dose.

Cause1: Empty Water Tank

You are experiencing no coffee or water issue in your Nespresso U, maybe because the water tank is empty. If there is no water in the tank, your machine cannot brew your coffee, or you cannot run a cleaning cycle.

How To Fix It: Fill The Water Tank

Check the water level in the tank; if the water level is low or the tank is empty, then add potable water to it.

Cause2: Limescale Accumulation

The limescale could be the reason why your Nespresso U is not dispensing coffee or water. It happens because of hard water, which contains high mineral content and causes the development of limescale, and over time the internal components of your machine start clogging. Thereby, limescale restricts the flow of coffee and water.

How To Fix It: Descale Your Machine

The only thing you can do to eliminate the limescale is descaling. Descaling is a crucial process of your brewing journey, which helps prevent the accumulation of limescale inside your machine and maintain optimum performance. So, get ready to descale your Nespresso U.

How To Descale Your Nespresso U?

Follow the descaling instructions below.

Empty the drip tray and discard the used capsules from the capsule container.
Add 1 unit of Nespresso Descaling solution and 0.5 L of water into the tank.
Place a container of 0.6L below the coffee outlet.
Push one of the buttons to start the machine. Your machine will start heating up, and the buttons will begin flashing. As the flashing lights become steady, it indicates your machine heats up.
Now, enter the descaling mode. Ensure the slides are closed, and push all three buttons simultaneously for three seconds. You will hear a short beep sound, which confirms the descaling mode.
Open the slider window, and press all three buttons simultaneously for three seconds. A short beep sound will confirm it, and the buttons will start flashing quickly, indicating the machine is operating.
Close the slider to begin descaling; your machine will stop when the water tank goes empty.
Refill the water tank with the used descaling solution collected in the container and touch any of the three buttons to repeat the process.
Empty the water tank, drip tray, cup support, and capsule container, then rinse them thoroughly. After that, add potable water into the water tank for the rinsing step.
Now, touch any of the three buttons to begin the rinsing. Your machine will stop when the rinsing cycle finishes.
Exit the descaling mode by pushing all the buttons simultaneously for three seconds. A short beep sound will indicate your machine has exited the descaling mode.

Problem 3: Why Is Coffee In My Nespresso U Not Hot Enough?

A perfect coffee has steam rising from the surface, indicating the coffee is piping hot. But wait, your Nespresso U is not brewing a hot coffee? Oh man, I can understand how it feels when your beloved coffee machine fails to meet your expectations. But don’t worry; I am here to assist you in troubleshooting this issue with Nespresso U. Let’s explore the causes of why the coffee in your Nespresso U is not hot enough and how you can resolve this issue.

Cause1: Use Of Cold Cup

Your coffee is not hot enough because you pour it into a cold cup. Why am I saying a cold cup? Because the cup temperature is different from the coffee temperature, which is hot. And when you pour steaming coffee into a cold cup, some heat may transfer to the cup to warm it. Thereby the warmth of your coffee decreases.

How To Fix It: Preheat Your Cup

To maintain the warmth of your coffee, consider heating your cup before brewing. You may preheat your cup in several ways.

Add hot water to your cup and let it remain for a few minutes before pouring your freshly prepared coffee.
Rinse your cup with boiling water.
You can also use a cup warmer to keep your coffee warm.

Cause2: Mineral Scale Deposition

Your Nespresso U is not brewing hot coffee; it might be because the mineral scale has deposited on the heating element. As the name suggests, the heating element is to heat the water to brew your coffee. And when layers of mineral scale cover the heating element, it prevents the water from being in contact with it. It can no longer heat the water to the required brewing temperature. Hence, you end up sipping a less flavorful, lukewarm coffee.

How To Fix It: Descale Your Machine

If the mineral scale deposition is the culprit of the problem of why your coffee is not hot enough, then you need to descale your Nespresso U. Descaling helps remove the mineral scale layers from the internal components of your machine, including the heating element. For descaling instructions for your Nespresso U, see the section” How To Descale Your Nespresso U” under “Problem 2( Cause 2)”.

Problem 4: Why Does The Slider Of My Nespresso U Not Closing Completely?

Are you anticipating a delicious coffee from your Nespresso U to fulfill your cravings? And you find out the slider of your machine is not closing completely. Oh man, what’s the problem with the slider? Why is it not closing completely? Relax, my friend! If you are trying to figure out why the slider of your Nespresso U is not closing completely, then I have got the answer for you. Read out the cause below and the solution to fix the partially closed slider of your machine.

Cause: Capsule Container Is Full

The slide of your Nespresso U is not closing because the capsule container is full of used capsules and not letting you close the slider of your machine. It can be the most annoying thing when you need your caffeine fix.

How To Fix It: Empty The Capsule Container

Remove the capsule container, discard the used capsules, and return the container to the machine.

Problem 5: Why Is My Nespresso U Not Start Brewing?

Are you eagerly waiting for your morning caffeine fix from your Nespresso U? But you are disappointed when your Nespresso U refuses to brew your coffee? I understand how it feels when you cannot prepare a coffee from your Nespresso U and can’t find the cause behind this issue. But to help you fix your Nespresso U, I have figured out the causes of why your Nespresso U isn’t brewing and how you can fix it. Check out the reasons listed below and return your machine to brewing mode.

Cause1: Slider Is Not Closed

Your Nespresso U does not start brewing your coffee because the slider is not closed completely. But what is causing the slider not to be closed completely? It is the capsule container that is full of used capsules and prevents the slider from closing the capsule compartment, and if the slider is not closed, your machine will not enter the brewing mode.

How To Fix It: Empty The Capsule Container

Check the capsule container; if it is full of the used capsules, discard them and put the container back in the machine.

Cause2: Water Tank Is Empty

An empty water tank could be why your Nespresso U isn’t starting to brew your coffee because water is essential in the brewing journey. So, If the tank is empty, no water will be there to blend the coffee beans. Hence, your machine will not start brewing.

How To Fix It: Fill The Water Tank

Check the water level in the tank; if the tank is empty, then fill it with fresh potable water. It’s crucial to check the water tank before you start brewing your coffee.

Cause3: Incorrect Orientation Of The Capsule

Your Nespresso U isn’t brewing as expected because you have not placed a capsule in its correct position. Normally to start brewing, your machine detects the capsule and then punctures it to blend the coffee beans. But how can a machine detect a capsule if it is not in its position? Not possible! Right? Hence, your machine will assume there is no capsule for brewing.

How To Fix It: Place The Capsule Correctly

Open the slider of the machine and check the capsule position; if it isn’t correct, place the capsule correctly and close it.

Problem 6: Why Is My Nespresso U Leaking?

The thoughts of brewing and smelling the aroma of freshly brewed coffee with your Nespresso U give you immense pleasure. But when you encounter a leakage, all the temptations of brewing a coffee get ruined. I know it’s overwhelming to face such a situation, and you don’t know how to fix it but don’t freak out; I will tell you why your Nespresso U is leaking and what you can do to resolve the leakage issue. Let’s fix this issue by reading the causes and solutions mentioned below.

Cause: Wrong Position Of Water Tank

If your Nespresso U is leaking, the problem is with the position of the water tank. You have not securely placed the tank on its base. The incorrect tank placement is causing the water to leak out of your machine and messes with your kitchen counter.

How To Fix It: Place The Water Tank Correctly

Detach the water tank from its arm, place it again, and ensure you put it correctly so it won’t leak out this time. Also, check the lid of the tank is firmly closed and that there are no cracks in the water tank.

Problem 7: Why Is The Coffee Flow Unusual In My Nespresso U?

Getting a perfect crema on your coffee increases the pleasure of having it. But when the coffee flow is inconsistent, it cannot create a smooth crema on your coffee. Are you also experiencing an unusual coffee flow in your Nespresso U? Oh, it must be irritating, especially when you don’t know how to fix it. Don’t worry, I will tell you the possible solution to this problem, but first, you should read the cause behind this unusual coffee flow. Let’s check it out below!

Cause: Incorrect Placement Of Water Tank

You are experiencing an unusual coffee flow because of the incorrect position of the water tank. But how does the position of the tank affect the coffee flow? Well, when you do not place the water tank correctly, the right amount of water will not be accessible for brewing which causes an imbalance in the pressure system and will result in uneven coffee flow.

How To Fix It: Reposition The Water Tank

Some problems have the most basic solutions, but they appear as complex ones. Just like the unusual coffee flow, here you need to reposition the water tank. So, remove the water tank from the machine and place it correctly.

Problem 8: Why Is The Light In My Nespresso U Flashing Alternatively From Back To Front?

If you are an avid coffee drinker, you must be a daily user of your Nespresso U and know all its blinking indications. Still, sometimes you get confused when your machine starts blinking alternatively e.g. from back to front, and you don’t get the message behind this alternative blinking issue. But don’t worry! I have figured out why your machine faces a problem of alternative light flashing from back to front, so you can fix it and brew a delicious coffee again. Let’s troubleshoot this issue together.

Cause1: Capsule Container Is Full

The lights on your Nespresso U are flashing alternatively from back to front because the capsule container is full of used capsules. The capsule container has the capacity to hold 10 used capsules.

How To Fix It: Empty The Capsule Container

To fix the alternative back-to-front flashing of lights:

Remove the capsule container and discard all the used capsules.
Place the container back on the machine.
Touch any of the Buttons.

Cause2: Capsule Blockage

Your Nespresso U flashes back to the front because a capsule has become stuck inside the holder.

How To Fix It: Remove The Stuck Capsule

Open the slider and look inside for a blockage of the capsule; if you see a capsule stuck inside, remove it. Then, press any of the buttons.

If the problem persists, there might be some other reason behind this alternative light flashing. You need to call the Nespresso Club for assistance;

When your life revolves around brewing delicious coffee with your Nespresso U, you can’t help but feel a sense of comfort. Wait a minute! Your Nespresso U suddenly starts flashing quickly, but why is it happening so? You might have got worried about this sudden flashing of your machine but don’t worry; I am here to address this issue that you are dealing with. Let’s not wait any longer and jump right into the causes and the possible fixes of this problem mentioned below.

Cause1: Your Machine Is In Descaling Mode

The reason why your Nespresso U is flashing quickly is that your machine is in descaling mode. Maybe you have mistakenly entered this mode, or your machine has stuck in it, but don’t worry about it. The descaling mode is to remove the mineral deposits from your machine and keep it in good working condition throughout its lifespan.

How To Fix It #1: Exit The Descaling Mode

If the lights are constantly flashing and won’t stop for a second, exit the descaling mode by pushing all the buttons simultaneously for three seconds. A short beep sound will confirm your machine has exited the descaling mode.

Problem 11: Why No Coffee, Just Water Comes Out Of My Nespresso U?

Are you waiting for your delicious coffee to flow out of the outlet? But instead of coffee, only water comes out. A problem has come to your doorstep because your Nespresso U is acting strangely. You must be trying to figure out the root cause of this issue, and for your help, I came up with this guide. That’s how your half problem is solved, just read out the cause and the solution mentioned below to resolve this problem, and thank me later.

Cause: Slider Is Open

Your Nespresso U is not dispensing coffee; only water is dripping out of the coffee outlet because the slider of your machine is open. How does the open slider not letting the coffee flow out? When the slider is open, your Nespresso U cannot enter the brewing mode, and water flows through the machine without passing through the capsule. Therefore no coffee comes out of your machine.

How To Fix It: Close The Slider

To fix the no coffee flow issue in your Nespresso U, pull the slider to close it so that your machine can enter the brewing mode. As you close the slider, your Nespresso U will allow the water to pass through the capsule and start brewing your coffee. The coffee will flow out once the brewing completes.

Problem 12: Why Does The Water Or Coffee Flow In My Nespresso U Not Stop Even By Pushing Any button?

As you start brewing your first cup of the day, you notice the water or coffee flowing out of the coffee outlet endlessly, no matter what you do to stop the flow. Damn! You encounter the worst thing anyone can ever imagine. But what causes this issue, and how can you fix it? Haven’t you found out yet? Don’t worry; I am here to tell you why it is happening with your Nespresso U and provide simple solutions to fix your faulty coffee maker. Let’s get into this!

Cause: Damaged Solenoid Valve

The most probable cause of the water or coffee not stopping in your Nespresso U machine even after pushing the button could be malfunctioning of the machine’s internal mechanism, particularly the solenoid valve or the flow meter. These components regulate the flow of water or coffee; when activated, the solenoid valve opens to allow water to pass through and then closes to stop the flow. And if they are faulty, they may fail to function as intended, and you encounter this situation where water does not stop flowing.

How To Fix It: Send Your Machine For Repair

If the solenoid valve is faulty or damaged, in such cases, it is recommended to have the machine checked and send it for repair by contacting Nespresso Customer Support.

Problem 13: Why Does My Nespresso U Turn Off Automatically?

Hey coffee lover! Does your Nespresso U switch off automatically? Even though you didn’t press the power button to switch it off. Then what is causing your machine to turn off on its own? You must be having negative thoughts like maybe there is some technical fault in your machine or any other reason, and you will lose your machine. Hold on a minute, my friend, and take a deep breath because I will discuss the cause of the sudden shutdown of your Nespresso U and what you can do to get your machine running again. Let’s find out!

Cause: Nespresso In Automatic Off Mode

Your Nespresso U coffee machine switches off automatically due to the power-saving feature. All the Nespresso machines have this power-saving feature, which enables the machine to shut down on its own after nine minutes of inactivity. This feature helps you in saving energy and protects your machine against severe damage like overheating.

How To Fix It: Touch Any Of The Buttons

To get your coffee maker back to operating mode, touch any of the buttons or push the slider of your Nespresso U. You can also change the auto-off timer from nine minutes to thirty minutes, push and hold the Lungo and Ristretto button up to three seconds and ensure the slider is closed while you are doing this. The Espresso button will flash once to confirm the timer settings.

To get back to the default settings of your Nespresso U, follow the steps below.

Press the Espresso and Lungo button simultaneously, and hold them for four seconds. The Ristretto button will flash for confirmation of the factory setting reset.

Problem 14: Why Is My Nespresso U Not Dispensing The Correct Amount Of Coffee?

Are you worried about the strange behavior of your Nespresso U? Your Nespresso U is not dispensing the correct amount of coffee, oh no that seems an issue as it’s a complete mood spoiler in the early morning when you are all set to leave for your work. But don’t worry; I have the practical solution for this problem you are currently dealing with. So take a chill pill and read out the causes and their possible fixes below to troubleshoot this problem.

Cause1: Cup Size Setting Has Changed

Your Nespresso U is not dispensing the correct amount of coffee because you have mistakenly changed the previously programmed volume of your coffee. It happens when you click the button to start brewing but click it again to stop the flow before the programmed volume flows out.

How To Fix It: Restore The Default Settings

To fix this issue, you need to reprogram the volume, but first, you need to restore the default settings on your Nespresso U.

Follow the step below for a factory setting reset.

Press the Espresso and Lungo button simultaneously, and hold them for four seconds. The Ristretto button will flash for confirmation of the factory setting reset.

After the factory reset, reprogram the volume according to your liking by following the steps below.

You can program the volume for any of the buttons of your Nespresso U. Open the slider entirely and insert a Nespresso capsule.
Touch and hold any button while closing the slider until the coffee reaches the desired volume. The other two buttons will flash, indicating the water volume is programmed for the button you have used for programming.

Cause2: Limescale Deposition

Limescale deposition might be the culprit of this problem. Minerals from hard water precipitate while heating up for brewing and form layers of limescale. This build-up of minerals can cause blockages in your machine’s internal pipes, affecting the coffee flow. That’s how you are not getting the correct amount of coffee from your Nespresso U.

How To Fix It: Descale Your Machine

To get rid of limescale, you need to descale your Nespresso U. Descaling helps clear the blockage by removing the limescale deposits from the internal components of your machine. To learn the descaling procedure of your machine, see the section ‘’How To Descale Your Nespresso U’’ under “Problem 2 (Cause 2)”.

Problem 15: Why Does My Nespresso U Produce Weak Or Watery Coffee?

Going to bed with a dream of waking up to a perfectly rich and bold Espresso shot from your Nespresso U, but all the anticipation turns into sadness when your Nespresso U greets you with a weak and watery coffee. If you are experiencing a weak and watery coffee issue in your Nespresso U, I genuinely feel sad about you, and that’s why I came up with the reason which is causing you to have a watery coffee, along with the cause I have figured out their solutions. So, let’s get started and troubleshoot this issue and resume drinking a perfect bold Espresso shot.

Cause1: Inaccurate Water Volume

You are getting a weak or watery coffee from your Nespresso U, probably because you have programmed an incorrect water volume for coffee. Such as the Espresso button on your machine to brew an Espresso with a specifically designed small espresso capsule, which is to brew 40 ml of coffee, and you programmed it for up to 100 ml, which is different from the capsule size. That’s how you will end up getting a weak or diluted coffee.

How To Fix It: Restore The Default Settings

To fix the incorrect volume, you need to restore the default settings on your Nespresso U by following the steps below.

Press the Espresso and Lungo button simultaneously, and hold them for four seconds. The Ristretto button will flash for confirmation.

Cause2: Using Low-Quality Third-Party Capsules

Your Nespresso U is brewing a weak and watery coffee, probably because you are using low-quality third-party capsules containing low-quality coffee grounds. The coffee beans are not properly roasted and ground, resulting in a weak coffee.

How To Fix It: Use Good Quality Third-Party Capsules

To fix the weak coffee issue, use good quality third-party capsules which contain premium quality coffee grounds and can give you rich, bold, and perfectly flavored coffee. Some of the good quality third-party capsule brands are listed below.

Peet’s Coffee Variety Pack – Best Overall.
Lavazza Variety Pack – Budget Pick.
Cafe La Llave Decaf – Best Decaf.
Starbucks Mild Variety Pack – Best Mild Intensity.
Meseta Coffee – Best Organic.

Cause 3: Reusable Plastic Capsules

Your Nespresso U produces a weak and watery coffee, most likely because you are using reusable plastic capsules. They are undoubtedly environmentally friendly but cannot give you a perfectly blended coffee because some reusable capsules cannot tolerate the same water pressure while blending the coffee beans compared to the disposable Nespresso pods. And which could lead to a weaker brew. Also, some coffee capsules manufactured by third-party brands do not function optimally with a Nespresso Machine. For example, aluminium capsules work better than plastic ones.

How To Fix It: Use Reusable Steel Capsules

Use reusable steel capsules instead of plastic ones; why am I saying this? Because the reusable steel capsules are designed with consistent brewing mechanisms and help extract the optimal flavor of coffee grounds.

Note: Steel Capsules can damage the puncture needle of your machine.

How To Fix It #2: Use Original Nespresso Capsules

The reusable steel capsules have a major drawback of damaging your machine; it’s better to use the original Nespresso capsule, which is originally designed for your Nespresso U rather, than using the reusable capsules.

Cause 4: Use Of Pre Ground Coffee

Another possible reason your Nespresso U is brewing a weaker coffee is that you are using pre-ground coffee in the capsules. When you buy pre-ground coffee, you may not know when they were roasted and ground. Maybe somebody ground them a month ago. And with time, these coffee grounds change their taste, and when you use this pre-ground coffee, it will give you a weaker brew.

How To Fix It: Use Whole Beans

A better solution to your weak and watery coffee is using whole beans instead of pre-ground coffee. Take whole beans, roast them, and grind them yourself right after roasting so the flavor remains perfect as compared to pre-ground coffee, which was ground a long time ago because ground coffee starts losing its aroma and flavor just after thirty minutes.

Cause 5: Using Too Coarse Grounds

It might be possible that the coffee beans you are using are too coarse, probably because your grinder is not working correctly; that’s why your Nespresso U is making a weaker and watery coffee. How do coarse grounds cause a weak coffee? When you brew with coarse grounds, the water will just pass through the grounds, giving you a weak cup of coffee. The size of grind particles determines how quickly a coffee releases its flavor while brewing.

How To Fix It: Use A Different Coffee Grinder

If your coffee grinder is not working correctly, use a different coffee grinder and adjust the grinder to the Espresso size to brew an espresso coffee. The espresso size is finer, but the best grind size is medium.

Problem 16: Why Is My Nespresso U Making Loud Noises?

If you are a coffee lover, you must love hearing the brewing sound of your Nespresso U, which gives you a surety that you will have a delicious coffee in your hand within a few minutes. But things got messed up when your Nespresso U started making inappropriate loud noises. You get worried as the loud noise indicates something is wrong with your machine, but you don’t know what is causing this loud noise. There could be various reasons behind this noise; let’s explore the reasons and their solutions below.

Cause1: Limescale Accumulation In The Pump System

Your Nespresso U is making loud noises, probably because of the limescale accumulation inside the pump system. Generally, when you brew a coffee, you hear a typical vibrating sound of the pump system. The vibrating sound is generated when the pump’s piston vibrates and causes water to propel with pressure. But when limescale develops inside the pump system, it causes a change in vibrating noise, and you hear a louder noise from the pump.

How To Fix It: Descale Your Machine

To eliminate the inappropriate vibrating sound of the pump generating due to limescale, you need to descale your Nespresso U. For descaling instructions for your Nespresso U, see the section above,” How To Descale Your Nespresso U” under “Problem 2 (Cause 2)”.

Cause2: Sound Of Moving Parts

The unwanted noises could be coming from the moving parts of your Nespresso U, such as the drip tray and water tank. If you do not position the parts correctly, they will produce a vibrating sound while you are operating your machine.

How To Fix It: Position The Removable Parts Correctly

You need to reposition the drip tray and water tank to fix the unwanted vibrating sound from your Nespresso U. Place the parts securely so they will not produce any sound while the machine operates.

The button will flash until the heating element reaches the desired brewing temperature. You can select the desired cup size at this point, and the machine will begin brewing your coffee.
