Reasons Why Nespresso Milk Frother Not Working and Fixes

Some problems are rather simple and are solved within seconds. Others require a bit more input from your side.

So before you decide what your Nespresso Frother is for, check out if any of these reasons might be the case for its malfunctioning and find their best possible solutions.

1. Dirt On The Electrical Contacts

A common reason for the Nespresso coffee machine is the presence of dirt on the electrical contacts. Over time, grease, gunk, and milk residue can accumulate on these connectors, obstructing the flow of electricity.

Solution :

To tackle this issue, follow these steps:

  1. Switch off and unplug the milk frother from the power source.
  2. Inspect the connections on the bottom of the device for any visible dirt or residue.
  3. Prepare a solution of warm, soapy water and dip a toothbrush or wire brush into it.
  4. Gently scrub the electrical contacts to remove any accumulated dirt.
  5. Rinse the contacts with clean water and ensure they are thoroughly dry.
  6. For an extra level of cleanliness, use alcohol to wipe the contacts.
  7. Finish the cleaning process by spraying a contact cleaner on the connections.

2. Gunk On The Magnetic Whisk

If your Nespresso milk frother is receiving power but the whisk isn’t spinning or frothing the milk, there may be gunk or residue obstructing its movement.

Solution :

Follow these steps to clean the magnetic whisk:

  1. Remove the magnetic whisk from the milk frother.
  2. Prepare a solution of white vinegar and salt.
  3. Submerge the whisk in the solution and let it soak for a few minutes.
  4. Use a toothbrush or wire brush to scrub away any gunk or residue from the whisk.
  5. Rinse the whisk thoroughly with clean water and ensure it is completely dry.
  6. Reattach the whisk to the milk frother and test its functionality.

3. Broken/Lost Magnetic Whisk

Another possible reason for your Nespresso coffee machine and milk frother not working is a broken or lost magnetic whisk. 

Solution :

To solve this problem, the following steps are recommended:

  1.  Take a toothbrush or towel.
  2. dip it in soapy water, and gently scrub the magnetic whisk to remove all milk residue that might be causing malfunctions.

4. Burnt-Out Heating Element (Advanced Fix)

In rare cases, a burnt-out heating element could be the cause of your milk frother not working. The heating element, a copper strip located on a printed circuit board, is responsible for heating the milk to the desired temperature.

Solution :

  1. Open up the canister to gain access to the PCB. You’ll be able to easily see where the track has burned up.
  2. By soldering a small strip of copper over where the track had burned up. To do this, we had to scrape back some of the enamel to get access to some good copper.

Caution :

This is a slightly more difficult issue to fix, mainly because it requires dealing with electricity. If this doesn’t sound like you, then the best thing you can do is to contact a professional technician.

5. Burnt-Out Thermocouple and Blown Thermal Fuse (Advanced Fix)

The thermocouple and thermal fuse are safety devices that can fail if they become too hot. Unfortunately, thermocouples aren’t unbreakable. They can wear out from too much use, as well as burn out from short circuits or any other electrical issues.

Solution :

  1. disconnects the thermocouple from the PCB via a slip connector.
  2. When you put the new one in, make sure to apply some thermal grease to make sure it conducts the temperature properly.


  1. Exercise caution with advanced fixes, as they involve risks like electrocution and fire.
  2. Seek professional assistance for inspection and repair.

6. An Unsuitable Type of Milk

Is your Nespresso Aeroccino not frothing oat milk? Is your Nespresso frother not frothing almond milk? 

Both of these problems have the same thing in common: you’re using the wrong kind of milk. Proteins, sugars, and fats inside milk are the ones most responsible for creating creamy foam. Without these, there’s nothing to hold the bubbles, and the form will disappear fast. The same goes for the plant-based milk options.

Solution :

  1. Whole dairy milk (cow milk ) is arguably the best option for creating rich hot milk.
  2. If you still want to use alternative milk, we suggest that you try different brands and types to find the one that works best for your Nespresso frother.

With a Nespresso Barista Bluetooth milk frother, things are a bit different. With so many options available to personalize your drink, it’s easy to mix up the settings. And when that happens, the simplest fix is often the one that works best, which is a factory reset.

Solution :

  1. Press both arrows simultaneously for three seconds. This will bring you to the hidden menu.
  2. Now press the center button, which will confirm that factory settings have been restored.

8. Beyond Repair :

If you have followed the troubleshooting tips and your Nespresso milk frother still isn’t functioning properly, it may be time to contact Nespresso customer support. Nespresso offers various options for support, including phone, email, and live chat.

It is important to note that if your Nespresso milk frother is still under warranty, contacting customer support is the best option, as attempting to fix it on your own may void the warranty.
