Nespresso Milk Frother Not Working? [9 Tips to Fix it]

Is your Nespresso milk frother not working? This is a pretty common issue with Nespresso machines and it’s usually caused by a number of different issues.

We’ve listed the top 9 reasons for this and provided the fixes to get your Nespresso working again.

If you are a coffee person, the first thing you want in the morning is a perfect cup of coffee. Imagine what you would feel if you see that your Nespresso frother is not working. Being a modern device for coffee lovers, the Nespresso Aeroccino milk frother can have some problems while working.

The Nespresso machine can fail to work due to several reasons such as damage to electrical components, tripped outlet, or unsuitable milk. In this post, I’ve discussed the main reasons for the Nespresso frother not working.

Why is my Nespresso frother not working?

1. A Burned-Out Heating Element: 

One of the main reasons for the Nespresso frother not working can be the burned-out copper strip. The copper strip passes the current to the printed circuit board and is a cost-effective method.

Solution: To resolve this problem, you have to fix the printed circuit board. After opening the container of the machine, you will notice that there is a burned-out copper element inside. You will have to take out the burnt part and weld a little portion of copper over where the track that had caught fire.

2. A Thermocouple that Has Been Damaged

A faulty thermocouple can be another reason for your Nespresso frother not working. A thermocouple is an electrical component that senses the temperature of the milk. If the component is damaged it will alert the controller of the machine even if the milk is at the required temperature.

Solution: Replace the thermocouple for the Nespresso machine to work properly. It has a slide connection to the printed circuit board, therefore, it can be taken out easily. Before installing the new thermocouple in the Nespresso machine, add a thermal lubricant to transfer the heat from the processor to the controller.

3. Dirt on the electrical contacts

Make sure to properly clean the Nespresso frother machine after every use. If not it can cause grease, milk, or other materials to gather at the bottom of the station. The residue can cause different types of problems such as Nespresso frother not working, overheating, triggering the thermostat, or even preventing the device from operating.

Solution: The aeroccino milk frother must be cleaned with cold water and a sponge. It would be better to wash your machine with a hand rather than a dishwasher. You should properly clean the whisk so it does not have any residue left.

4. Magnetic Whisk 

A magnetic whisk is an important part of the Nespresso aeroccino milk frother that aids in mixing the ingredients for a perfect cup of coffee. With time, the gunk can gather on the whisk. If you do not clean the whisk after every use, it can cause the residue to get into the canister of the whisk. It will prevent the whisk to work freely.

If there is a hole left in attaching the whisk properly, the device will not be able to operate efficiently. A damaged magnetic whisk can be one of the reasons for the Nespresso frother not working. Being an electronic device, it can wear and tear over time. You should pay attention to the whisk attachment so it does not fall out.

Solution: Use an effective cleaning method for the gunk on the whisk. All you need is to follow some simple steps:

  1. Get half cup of white vinegar
  2. 1 tablespoon of salt
  3. Mix the ingredients and leave the whisk in it overnight.
  4. After that remove the whisk, the gunk will come off easily.

Make sure to place the whisk properly so it does not have any gaps left and can easily connect to the circuit board. 

If the Nespresso aeroccino milk frother has a damaged whisk, you have to replace it. The parts are easy to find, although they are costly they can go around the corner for a long time.  

5. Liquid damaged the electrical components.

Most people do not realize that it is not possible to wash an Aeroccino milk frother machine. If you try to wash the machine, the water can do damage to the electrical components causing the device not to start.

A Nespresso frother has four basic parts: a lid, magnetic whisk, frother, and power circuit. Wash the lid and the whisk separately, but the electrical components can’t get wet. It can damage the wires and may damage the entire device as well.

Solution: If your Nespresso foamer is not working due to damage to electrical components, you will have to buy a new one.

6. Nespresso aeroccino milk frother Not Pumping Milk

A Nespresso machine has 5 main parts: joint piece, foam selection dial, head unit, or spout elbow. The coffee deposits can cause the parts not to work efficiently.

Solution: Thoroughly clean the parts of the machine with hot water.

7. Loose connection

If your whisk or jug has a loose connection, it may fail to start. Place the jug properly on the base and correctly attach the whisk with the machine.

Solution: Ensure that your jug is fixed properly on the base. Hold it firmly so it gets placed perfectly. Make sure to securely position the magnetic whisk.

8. The Outlet Is Tripped:

Power surges can occur occasionally. Sometimes you may not be able to detect the power surge and plug the Nespresso machine. If the machine is not working, you might assume it is damaged.

Solution: The solution is to avoid plugging too many electric devices in one outlet. If the outlet trips, use the reset button to resolve the problem.

9. Improper use of milk (Milk type and too much milk)

You have to be careful about the type of milk and the quantity you are using. Overfilling the jug with milk will not allow the machine to frother at all.

Solution: Fill out the jug with the maximum limit of the milk. Choose the milk wisely that has high fat and is less watery such as oat milk, cashew milk, goat milk, or whole milk.

Nespresso aeroccino 3 troubleshooting methods

1. The Aeroccino does not begin:

  • Make sure to properly place the jug on the base.
  • Attach the magnetic whisk properly with the jug. 

2. The quality of the milk foam isn’t up to par:

  • For a Nespresso aeroccino to froth properly, you should use skimmed milk, either full or semi. The ideal temperature of the milk should be from 4 to 6 degrees Celsius.
  • Clean the components of the machine before using.

3. Blinking red button:

  • A blinking red button can indicate that the device is overheating. You can rinse the machine with cold water.
  • The whisk is not attached properly, is not attached, or is not able to operate due to gunk.
  • The amount of milk you are using is not enough. There is a maximum of two limits, you will have to fill one of them on the frother machine.

Beyond repair? Get a replacement.

The cost of repairing a damaged Nespresso foamer can be more than a replacement. It is better to get a new one. Rather than paying to get the motor fixed, getting a new magnetic whisk, or a thermocouple, you can opt for buying new Nespresso machine parts. There are multiple resellers available at eBay and Amazon that sell new and 2nd hand parts of the Nespresso machine.


Why Is My Nespresso Milk Frother Blinking Red?

The red blinking button on your Nespresso machine indicates something is wrong with it. It may not be heating, steaming, frothing, or operating.

  • When you are filling your jug with milk, make sure to fulfill the required limit. Do not overflow it, that will make a plausible fault.
  • The damaged or unattached magnetic whisk can prevent the Nespresso foamer from not working. Make sure to attach the whisk properly. If your whisk is damaged, replace it with a new one.
  • Also, if the machine gets too hot, turn it off and rinse it with cold water. The red blinking may be due to overheating.

Where can I get Nespresso milk frother replacement parts?

Getting replacements for your broken or damaged Nespresso erosion milk frother is easy. You can find the parts at an online or retail store. The cost for the lid is $16 and the whisk costs around $15.


Now, you are aware of all the possible reasons why your Nespresso frother is not working. A coffee machine requires regular cleaning, maintenance, and troubleshooting of problems. By taking proper care, the Nespresso machine can help you enjoy several cups of great coffee.

  1. Although it works fine, my Nespresso frother loses its inside coating at the bottom. What is the coating made of and should I be concerned about ingesting these particles?

    (FYI: I do not use soap or anything metallic to clean the appliance: only the tip of my fingers.)

    1. Jacques,

      That is really unfortunate. I am not sure how old your frother is and whether or not you are still within warranty, but this seems to be common with Nespresso frothers in that the ceramic coating appears to flake off or there appears to be a residue. Most users experiencing this issue suggest using dishwasher soap and a teflon brush after every single use. When it’s not cleaned every single time, some residue may become stuck to the bottom, cooking into the next batch. If left unchecked, this residue may turn black and flake off with time. If this is for sure the ceramic coating itself, I would not ingest the contents of the device, as it could be harmful to your health. In either case, I recommend reaching out to Nespresso support to see what your options are for your specific situation.

  2. Hello, I have the Nespresso aeroccino 3 frother. I don’t have the base (with power cord attached). Can I get a replacement base? I’ve not been able to find. Tx!!
