After making an espresso shot using a Nespresso machine, you want to make your favorite latte, but the Nespresso milk frother is not working properly
This is a very common troubleshooting issue with the Nespresso milk Frother and fixing the problem is pretty straightforward.
So you don’t need to panic and rush towards the market to buy a new one or head to a café to drink your coffee. All you need is to follow some instructions, and you can fix it by yourself!
In this article, we provide a complete step-by-step troubleshooting guide on why the Nespresso milk frother is not working properly, the possible causes, and provide a comprehensive guide on how you can fix it to get your Aeroccino milk frother working properly again.
8 Possible reasons WHY NESPRESSO MILK FROTHER NOT WORKING
The most common likely reason for the Nespresso milk frother not working is a dirty or misplaced magnetic whisk. Other reasons may involve the wrong type of milk or overfilling the jug, or the electrical components may be damaged.
These are the top reasons I have identified:
- Improper placement of the magnetic whisk
- Dirty or Damaged magnetic whisk
- Burnt heating component and thermocouple
- Dirt On Electrical Component Contacts
- The type of milk used isn’t suitable for frothing
- You are using too much milk
- The electricity outlet is tripped
- Water damaged the electrical components of the machine
Let’s now discuss each of these possible reasons, their causes, and solution for how to fix them.
Nespresso milk frothers have a magnetic whisk for whipping milk.
The magnetic whisk might get misplaced during frothing or cleaning and that causes the milk frother to malfunction.
If the light on your milk frother is blinking red, then improper placement of magnetic whisk is the possible cause.
Ensure that the magnetic whisk is attached properly to the nipple on the bottom of the frother.
Simply adjust the position of the whisk and it will hopefully solve the problem.
2) Dirty or Damaged magnetic whisk – Heating but not Frothing
If your Nespresso milk frother is heating the milk properly but not frothing it then the possible cause is a dirty or damaged magnetic whisk.
Regularly cleaning the magnetic whisk is important to keep it clean and ensure that it spins smoothly. If you don’t do it regularly the milk residue will build up over time and cause malfunctioning.
Take a toothbrush or towel, dip it in soapy water and gently scrub the magnetic whisk. It will remove all the milk residue and the whisk will start spinning properly.
Wear and tear and some unusual vibrations break the magnetic whisk attachment.
Sometimes, the small magnet present inside the whisk gets lost and that makes the magnetic whisk completely useless.
The best part is you can easily get a replacement that fits your Nespresso milk frother. And even a beginner can replace it easily.
The best choice is to buy them from amazon.
3) Burnt heating component and thermocouple
Burnt Heating element
The heating component is a copper strip printed on an electric circuit.
The heating component might get damaged if you use it in excess or sometimes may be because of irregular electricity loads.
Unscrew the milk frother and get access to the PCB. You can easily spot the burnt heating element.
You can fix this by soldering a small strip of copper over where the track got burned.
Burnt or damaged thermocouple
The thermocouple is a small electronic device present inside a milk frother. The primary objective of the thermocouple is to monitor the temperature of the milk, and once the optimum temperature is achieved, it will turn off the frother automatically.
If the thermocouple gets damaged the milk frother will stop working.
To resolve this, you will need to replace the thermocouple.
The damaged thermocouple can easily be disconnected from the PCB via a sliding connector. Simply remove it, and add a new thermocouple.
Note: These fixes are only recommended if you are a tech-savvy person and know how electric component works. Otherwise, get assistance from a technician.

4) Dirt on electrical component contacts
The Aeroccino milk frother gets its power from the round plastic connector located at the bottom of the machine.
Sometimes the connector gets dirty because of the accumulation of grease, dirt, and milk residue, especially if it overflows.
If the frother won’t turn on or seems to be getting fluctuating power then this might be the cause
Once dirt begins to build up, it will trap moisture and erode the contacts and that is even worse.
The easiest solution is to thoroughly clean the plate with a wet cloth or toothbrush
Unplug the machine and turn the frother upside down and inspect both the frother and base station connections.
Take a small brush and soapy hot water and scrub it thoroughly until you can see the dirt has been removed completely.
5) The type of milk isn’t suitable | Spinning but not frothing
If your Nespresso milk frother is spinning properly but not forming a froth. Then most probably you are using the wrong type of milk.
Some of the worst kinds of milk for Nespresso milk frother are:
- Almond milk
- Cow’s milk ( 2% or lower)
- Soy milk
- Coconut milk
These kinds of milk are too watery to be used for frothing. Nespresso milk frother heats them, but unfortunately, it won’t create any form.
The only solution is to choose milk wisely that precisely fits your Nespresso milk frother requirement.
Usually, milk that is higher in fat, less watery, and contains little sugar performs the best.
Some of the best milk for Nespresso milk frother are:
- Oat milk (low-fat, regular, and full-fat)
- Cashew milk (full-fat)
- Goat milk
- Whole milk

6) You are using too much milk
While frothing, sometimes you overfill the pitcher and that prevents your machine from frothing at all.
It is recommended to use the right amount of cold and fresh milk.
There are two lines of indication inside the Aeroccino frother:
- 8 ounces for producing just hot milk
- 4 ounces for producing frothed milk
While the capacity of the jug of Aeroccino frother is certainly greater than that but you must follow the guidelines for proper functioning as milk expands when heated.
7) Electricity outlet is tripped
Sometimes your Nespresso milk frother does not work because the electrical outlet of the machine has suffered a power surge.
Sometimes there are too many electronic devices plugged into the same outlet which can cause this issue.
Try plugging the frother in some other electrical outlet and hopefully it will solve the issue.
8) Water damaged the electrical components of the machine
Washing the Nespresso milk frother with water can damage the electrical components inside it. If water gets to the bottom of the machine where most electrical components are present, they become wet and eventually stop working.
You can rinse the magnetic whisk and lid. However, you can’t submerge the frother in water, and also it is not dishwasher safe (it is clearly mentioned in the user manual)
Unfortunately, if the milk frother stops working while washing, it’s time to buy a new one because you can’t repair it.
Fortunately, the milk frother is relatively cheap and can be bought online, or you can purchase different components separately if you need them.
The Nespresso milk frother starts blinking red when the machine is overheating. This might happen if you don’t clean your frother regularly.
Milk residue accumulates inside the machine over time which causes inefficiencies in the heat transfer and because of that, your frother starts overheating.
It is recommended to rinse the frother with water after every use. Otherwise, you will face this problem.
Get Replacement parts or get a new one
Sometimes it’s not worth fixing things. If you’ve found that the motor has burned out or one of the above solutions failed to fix your problem, your best bet may be to purchase a new frother.
If some parts of your milk frother are malfunctioning then it’s best to just replace those parts instead of buying a new one. For example, you can easily purchase a replacement magnetic whisk from amazon.
