If you enjoy coffee, a perfect cup is what you desire first thing in the morning. Consider how you might feel if you discovered that your Nespresso frother was broken. Despite being a cutting-edge appliance for coffee enthusiasts, the Nespresso Aeroccino milk frother occasionally experiences technical difficulties.

The Nespresso machine may stop functioning for several reasons, including faulty electrical components, a tripped outlet, or inappropriate milk. This post covers the primary causes of the Nespresso frother not working.

Is your Nespresso milk frother not working?

If your Nespresso milk frother isn’t working, it’s probably because it needs to be descaled. Descaling is an essential part of maintaining your coffee machine, and it’s something you should do every few months. You’ll need to purchase a descaling solution for your Nespresso milk frother. We recommend using the Nespresso Descaling Solution, which is designed specifically for use with Nespresso machines

Once you have your descaling solution, follow the instructions on the packaging. Generally, you’ll need to add the solution to the water reservoir of your machine and run a brew cycle. After the cycle is complete, empty the water reservoir and rinse it out several times. If your milk frother still isn’t working after descaling it, there may be a more serious issue.

In this case, we recommend taking it to a qualified technician for further diagnosis and repair or following the below 7 steps:

Is your Nespresso milk frother not working?

Solution 1: Check if the frother is turned on

Sometimes we forget to turn on the frother. If you turned it off for some time and it’s not working, try turning it on. It’s simple, but sometimes we tend to forget about it. Check the power button to see if it is on. If it is not, then try holding the button for three seconds to turn on the frother. If you still cannot turn it on, then turn off the machine and try again in a few minutes.

Solution 2: Check if the power cord is plugged in

Even if the Nespresso frother is turned on, there may be a problem with the power cord. Try plugging the power cord into a different outlet. If the frother still does not work, If you are using a surge protector, check to see if the surge protector is plugged into an outlet.

Make sure the Nespresso frother is plugged into the proper outlet. If it is, then unplug the machine and plug it back in again. If the Nespresso frother still does not work, then you may need to contact your electrician to troubleshoot the problem. 

Solution 3: Check if the frother is dirty

If your Nespresso frother needs to be fixed, there may be several things that you can do to resolve the issue. Some common causes of a malfunctioning frother include dirty filters or clogged ports. In order to diagnose the problem, you will need to remove the frother head and clean all of the components.

The Aeroccino is powered by its base station, which is hooked into a wall socket, as you are already aware. To make an electrical connection, the “male connector” on the base must be inserted into the “female connector” on the canister. These two connectors may become soiled, after all.

The power supply may only reach the frother if they have enough dirt on them. The ground is typically a mixture of dust and milk solids. They combine to form a solid that collects moisture near the real electrical connections.

Everyone is aware of what happens in that scenario, right? Rusting. This may be a possible reason why your frother won’t turn on. Fortunately, this is a reversible issue. Most of the time, cleaning the contacts will restore your Aeroccino’s functionality. You’ll need a few items in order to do that:

  • Clean water
  • Little brush
  • Alcohol (isopropyl, not tequila) 
  • Towel or wipe
  • Metal brush (in case of corrosion)
  • Spray contact cleaner


  • Make sure your frother is unplugged from the wall before you begin. You can short a circuit and even ignite a fire when in touch with water.
  • Take a small basin and fill it with soapy water so you may dip the brush in it afterward.
  • Start cleaning out the grime from your electrical contacts.
  • Rinse off the soapy water after cleaning.
  • Before repeating the process with alcohol this time, completely dry the contacts.
  • If the contacts are rusted, you should use a wire brush rather than a conventional one. You won’t harm the connections, so don’t be concerned.

Solution 4: Check if the frother is broken

Check if your frother is broken if the issue still persists. A missing magnetic whisk or a burned-out heating element are two common causes. You might occasionally break or damage the magnetic whisk attachment due to normal wear and tear or an unavoidable, unexpected accident.

Here, it frequently happens that the tiny neodymium magnet slips out and disappears, rendering the whisk unusable. A new whisk for your aeroccino milk frother is simple to find. You can purchase these through your local Nespresso retailer, but doing so is expensive, and there may be significant delays in receiving the components because most stores don’t stock them.

According to our research, the cheapest and most straightforward way is to buy directly from Amazon. 

If your frother appears to be heating up, but the whisk does not appear to be moving, an element may have burst. This problem is a little more challenging to resolve because it involves electricity.

Try to fix your system by using the methods below if you’re good at that sort of thing. But if you’re not, you should always leave it to the experts. The heating element for the Aeroccino is made of copper traces on a printed circuit board.

Now, these things degrade quickly, so don’t be shocked if it does. They are also a quick and inexpensive fix. The printed circuit board of your Aeroccino has to be opened, and any burned patches need to be checked for. Scrape off a little portion of enamel, and then solder that area with a thin copper strip.

Solution 5: Use distilled water

Use distilled water to wash your frother. When the frother runs, pour distilled water into it and let it run. This will remove any residue that may be clogging up your frother. This solution lets you get the most out of your coffee maker.

The water level indicator will come to a point where it will no longer fill, and then it will be completely empty. Now, this is an easy fix, and it won’t cost you a lot of money. But it may take a while for the problem to be solved. First and foremost, it is the water that is the culprit here.

You can’t just use tap water because that can cause more problems. The best way to ensure you don’t have any issues is to have your frother. Washed regularly. This will keep it in top shape and allow it to function correctly.

Solution 6: Clean the frother

It is tough to clean a frother. Over time, milk scum will accumulate on the whisk. This one applies to those who don’t take the whisk off and rinse it between brews.

The gap between the whisk’s hole and the nipple it slides over within the canister has a very narrow tolerance. The whisk cannot spin freely if it becomes clogged with dirt.

The simple fix is gently and thoroughly cleaning the whisk with a potent cleaning agent. You’ll need white vinegar, about half a cup, a little wire brush or toothbrush, and a spoonful of salt. The whisk should soak in the salt and vinegar mixture for a few hours or overnight in a glass container.

After washing, please wash the items, rinse them with clean water, and then scrub them with the toothbrush to remove any remaining filth. You should be good to go once you put the whisk back in the milk frother.

Solution 7: Buy a new frother

Occasionally, a problem is not worth solving. The best option might be to purchase a replacement frother if you discover that the motor has burned out or if any of the above solutions have failed to resolve your issue.

With third-party resellers offering both new and used complex parts on marketplaces like Amazon and eBay, these are pretty simple to find.

Before making a purchase, be sure you pick the right one for your machine. Here are some things you need to consider before buying a new frother.

  • Capacity: You want a device that can accommodate both your family’s and your own requirements.
  • Convenience: Consider your intended purpose for the device. Pod and capsule machines are the ideal alternatives if you’re searching for a simple solution that requires little setup or labor.
  • Straightforward controls: Look for equipment that you can operate efficiently. Digital displays and indicator lights on machines provide a straightforward and uncomplicated operation.


Seven possible factors are typical causes of the problem when your Aeroccino milk frother works poorly.

A defective or misplaced whisk or a dirt buildup are two of the most frequent issues. Both issues are simple to resolve, especially if you adhere to the advice given above. Therefore, all you need to do to solve the problem independently is follow the instructions in this article.

However, if the frother itself is damaged, you’ll need to get professional assistance to fix it, or it might be necessary to invest in a replacement device.

In this case, you will need to either replace the frother or have a service technician clean and re-seat it.
