Nespresso Milk Frother Not Working: Probable Causes And Troubleshooting

Have you ever turned on your Nespresso Milk Frother on such a regular day only to find that somehow the milk isn’t frothing? Don’t be concerned. Take a deep breath and relax.

According to Nick from Your Coffee & Tea Essentials, this is a very common problem with Nespresso machines, and fortunately, it is also rather simple to solve. So, before you dash out to get a new one or reserve a table at a café, it’s possible that you can restore it yourself!

Possible Causes And Solutions


There could be a number of reasons why your Nespresso Milk Frother isn’t working, but don’t panic; just like any other problem, your frother has a solution. Just attempt to figure out what’s wrong, and you’ll be fine.

1. There’s No Rotation

You may notice that the milk within the frother is just not rotating at times, which might be inconvenient.


Disinfect the Frother

The first thing you should do if you’re having this problem is making sure you’re cleaning your frother correctly. There could be something stuck within the frother, or there could be dust or grime stuck to the lower gears, both of which you will need to clean.

So, make sure you wipe the lower piece first, and then clean it well from the inside, using lukewarm water. That will undoubtedly assist you with any such issues, and will not get trapped in this manner.

Cleaning your milk frother with only a moist towel after each use is a great method to avoid milk getting trapped in the frother.

Use skim milk if possible

The cream in the milk might also cause this issue since it can thicken and prevent the frother from whirling.

You must verify that when you are experiencing any such issues, you utilize skimmed milk within the frother, as this will assist you in resolving all such concerns with milk rotation. Skimmed milk would be ideal for giving you the best experience with the Nespresso milk frother.

2. You’re Having Trouble Starting


Your Aerocinno milk frother may not start on multiple occasions, which might be inconvenient. If somehow the Aerocinno milk frother does not start, and you’ve ruled out an evident electrical problem, there are a few things you can try.


The base should be clean

The first place you should inspect is the base of the frother, which should be free from dust, filth, and moisture. To resolve this, you must wipe the base well with a moist cloth and properly position the jug on the base. This ensures the frother rotates freely, without causing any problems while you operate the Aeroccino Milk Frother.

Check if the Whisk Is Attached Properly

Another thing to keep in mind is that the whisk should not have any issues, such as being loose. All you have to do now is make sure that the whisk is properly attached to the top of the jug. This will help ensure that your milk frother functions without any issues.

3. Electrical Contact With Dirt


The Nespresso milk frother is powered by a spherical plastic connector on the device’s bottom. The milk canister has a female connector, while the Nespresso machine has a male plug.

Depending on the machine model, this can also be a standalone base station, but the operation is the same. Grease, muck, and milk residue tend to accumulate in both of these connectors, especially if you’re dealing with a frequent overflow.

This is the most probable issue if the machine does not turn on or intermittently turns on and off. Crusted milk residue is the most common type of filth that builds up in a frother with time. When dirt begins to accumulate, it traps moisture and begins to corrode the electrical contacts.


Deep cleaning

Thoroughly cleaning the panel with water and soap and cleaning the contacts using a contact cleaner is a simple remedy. A dishcloth, dish soap, Isopropyl alcohol or Methylated spirits, a bristle or small wire brush, and contact cleaner spray are the things that you’ll need.

Start by turning off and disconnecting your machine (safety measure of course). Check both the connections on the canister as well as the base station by turning the frother canister upside down.

Scrub thoroughly with a tiny brush and a mug of soapy water until you notice the muck has been removed. A toothbrush is ideal for this task, and also keep one on hand along with the descaling solution and other cleaning supplies.

A scrub brush may be more appropriate if somehow the contacts are heavily rusted. Rinse away the soapy water. Dry completely before scrubbing with alcohol this time. After that, administer a good squirt of contact cleaning spray.

4. The Magnetic Whisk Has Gunk On It


When the milk frother is powered up, the very next thing is to make sure the milk whisker is functioning properly. Over time, milk residue can accumulate on the whisk. This issue is quite common if you don’t retrieve the whisk and rinse it between each brew.

The opening in the whisk as well as the nipple it slides over within the canister has a very limited tolerance. The whisk will be unable to spin freely if this becomes clogged with muck.


Moderate cleaning

A simple approach is to clean the whisk well using a strong cleaning solution. Half a cup of white vinegar, a tablespoon of salt, and a toothbrush or small wire brush are all you’ll need.

In a glass jar, combine the salt and vinegar, then lay the whisk in to rest for just a few hours, and if possible, leave it overnight. Remove the sponge after it has been soaked, rinse with fresh water, then scrape using the toothbrush to eliminate any excess filth.

Reconnect the whisk to the milk frother and you’re ready to go!

5. Magnetic whisk is broken


The magnetic whisking attachment can be damaged or broken as a result of normal wear and tear or an unexpected freak accident. The little neodymium magnet falling out and being lost is a typical problem here, rendering the whisk unusable.



A new whisk for your Nespresso milk frother is simple to find. You can acquire these through your local Nespresso dealer. However, they’re not that inexpensive, and getting them in can take a long time because most shops don’t keep them on hand.

6. The Outlet Has Been Disrupted


Your Nespresso milk frother may occasionally stop operating due to a power spike in your socket. This can happen as a result of a variety of factors. There are sometimes too many devices connected to the same socket or even in the same room.

Typically, the problem can be resolved by pressing the ‘Reset’ switch on that certain outlet part. Otherwise, there are alternative options for resolving the problem.


A simple procedure

Locate a functioning outlet then plug the frother into it for the time being. To avoid further power tripping, you may need to restart the circuit breaker or relocate some of the other appliances.

7. Not frothing at all


When frothing using your Nespresso Aeroccino, be mindful of the amount of milk you use. If the pitcher is overfilled, the machine will not froth at all.

It is suggested that you use cool, fresh milk. Inside the Aeroccino, there are two different indicator lines: 8 oz is usually the maximum limit if you want it to produce hot milk, and 4 oz is indeed the maximum capacity if you’re frothing milk.

If you don’t follow those rules, you risk getting less-than-ideal outcomes or letting the frother overrun. Keep in mind that heat expands.



It’s rather straightforward to prevent this difficult issue. Never fill your frother with more than 8 ounces of liquid. If your pitcher doesn’t have an indication, fill it all the way to the top of its magnetic whisker as a general rule of thumb. This will result in the ideal amount of foam.

Is the damage irreparable? Get yourself a new one. Things aren’t always worth repairing. If the motor has blown or none of the other repairs have worked, purchasing a replacement frother could be your best option.

Nespresso Milk Frother’s Red Blinking Alert

Don’t be alarmed if the power button on the Nespresso milk frother is flashing red. This usually happens whenever the device is overheated. Milk residue is the major cause of this. To avoid milk drying out and clumping on the inside of your frother, clean it immediately after each use. Make sure to use cool water as well as stay away from the electrical parts!


So, now that you’re aware of all the possible solutions and problems if your Nespresso milk frother stops functioning, put your expertise to good use! When it comes to operating a coffee maker, you must keep a close eye on maintenance, cleaning, and troubleshooting.

It’s all part of the package, and it’ll help you enjoy numerous cups of bliss while also extending the life of your Nespresso machine!
