7 Possible Reasons for the Malfunction of the Nespresso Frother


Multiple factors can contribute to the improper functioning of your Nespresso frother. While certain issues can be quickly resolved, others may require more involvement. Hence, before concluding that your frother is defective, it is recommended to consider these potential causes for its malfunction.

Dirt On the Electrical Contacts

The Aeroccino operates by being connected to its base station, which is plugged into a wall outlet. The canister itself has a " connector" that needs to be placed onto the "male connector" on the base, for proper electrical connection.

However these connectors can get dirty. If there's dirt accumulation it can hinder the power supply and prevent it from reaching the frother. Usually this dirt consists of dust and milk residue which forms a residue that traps moisture around the contacts. This can potentially lead to corrosion. Cause your frother to fail turning on.

Thankfully this issue is not permanent. Cleaning the contacts should usually be enough to restore the Aeroccino to its functionality. To do this you'll need an items:

  • Use a solution of water
  • Use a small brush
  • Isopropyl alcohol (not tequila)
  • Have a wipe or towel
  • Keep a wire brush nearby in case of corrosion

Please follow these steps carefully:

1. Before starting any work, disconnect the frother from the power source. Avoiding contact with water to prevent short circuits or fire hazards is crucial.

2. Prepare a small bowl with soapy water for dipping the brush.

3. Gently scrub the dirt off the electric contacts.

4. Once the cleaning process is complete, thoroughly rinse off the soapy water.

5. Allow the contacts to dry completely before proceeding to the next step. For this stage, use alcohol to clean the contacts.

Broken Magnetic Whisk

If your frother heats up without the whisk spinning, it may indicate a malfunction. This could be a result of incorrect positioning during the initial setup. However, it is important to note that these devices can be delicate and susceptible to damage with regular use. In such cases, it is advisable to consider purchasing a replacement. Fortunately, replacement parts are readily available both online and in physical stores.

Regarding the issue of gunk on the magnetic whisk, if you have neglected to clean your milk frother after each use, it is likely that your Aeroccino milk frother is not functioning properly due to excessive milk residue buildup. The good news is that cleaning the frothing whisk is a relatively simple task despite getting dirty quickly. To address this, you will need the following items: vinegar, salt, a small brush, and a wire brush.

Once you have gathered all the necessary materials, please follow these steps:

1. Combine approximately a tablespoon of salt with a cup of vinegar, and place the whisk inside.

2. Allow it to soak for up to a full day when most of the dirt should dissolve.

3. If any residue remains, use the brush to scrub it away.

4. Finally, rinse the whisk with warm water.

By following these steps, you can ensure optimal functionality and cleanliness of your milk frother.

The Heating Element Burned Out


This issue presents a moderately challenging task, primarily due to the involvement of electricity. If you possess expertise in this area, we recommend attempting the following steps to fix your machine.

However, if you are not well-versed in dealing with electrical components, it is advisable to seek the assistance of a professional. Please consider reaching out to Nespresso customer service for further guidance and support.

The Aeroccino milk frother utilizes copper traces on a printed circuit board as a heating element. It is not uncommon for these components to experience failure, but fortunately, they can be easily and affordably repaired.

Essentially, you must carefully open the Aeroccino frother and inspect the printed circuit board for any signs of burn marks. If identified, delicately remove the enamel and solder the affected area with a thin strip of copper.

The Thermocouple Is Damaged

The thermocouple is an integrated sensor used for measuring the temperature of milk. While operating the frother this sensor constantly keeps an eye on the temperature of the milk and adjusts it as needed. It automatically turns off the frother when the milk reaches the desired temperature to avoid any chances of burning.

Unfortunately thermocouples can wear out and get damaged due to use or electrical problems like short circuits. When a thermocouple becomes faulty it is recommended to replace it.

Thankfully replacing a thermocouple is a process. It is connected to the printed circuit board using a slip connector that can be easily detached. Just remove the thermocouple and install a new one.

There Is Too Much Milk In The Frother


While it is important to have an appreciation for milk, it is crucial to recognize the limitations of your Aeroccino. Excessive amounts of cold milk can lead to spillage or inadequate frothing. To prevent any mishaps, observe the interior of the Aeroccino milk frother. You will observe two indicator lines on the walls, denoting the maximum capacity.

The lower line signifies a limit of 4 ounces for milk froth preparation, while the upper line indicates a maximum of 8 ounces for non-frothing purposes. Adhering to these recommended quantities ensures a seamless milk frothing experience without complications.

You Are Using An Unsuitable Type of Milk


Not all types of milk foam in the same manner. Surprising? It certainly took by surprise. We have always stuck to one type of milk without considering it. However, upon closer examination, it becomes evident that milk's proteins, sugars, and fats play a crucial role in creating velvety foam. Without these components, bubbles cannot be retained, resulting in rapid dissipation of the foam.

When producing rich, hot milk foam, whole dairy milk (cow's milk) is arguably the optimal choice. Almond milk and oat milk offer similar frothing capabilities among plant-based alternatives. Interestingly, skim milk also works, albeit with a more bubbly foam rather than a creamy texture.

Unfortunately, the options for frothing milk are limited. Many plant-based milk alternatives, such as macadamia, coconut, soy milk, and rice, simply do not produce the desired foam. While you may observe a few bubbles forming, they will disperse as quickly as they appeared, leaving you without frothed milk.

Nespresso Aeroccino Troubleshooting

We have discussed various factors that may cause your Nespresso milk frother to have issues with frothing. However, how can you identify if something is amiss? There are four specific indicators of a problem:

  • The frother fails to start.
  • The milk doesn't froth or has a burnt taste.
  • The red light on all four buttons is blinking rapidly.
  • Milk overflows from the frother.

If you are experiencing any of these issues, several potential causes must be considered. Before attempting any repairs, it is important to carefully inspect each of these possibilities.

Resetting Your Nespresso Milk Frother

Final Thoughts
