Nespresso milk frother is not working

Why is my Nespresso frother not working?

Your Nespresso milk frother may not be working correctly for a few simple reasons. If frothy Milk is an essential part of your morning coffee, use the information below to tackle each problem.

Repair for a Burned-Out Heating Element

The Aeroccino frother’s heating element is nothing more than a copper strip on a printed circuit board. The design of this device is relatively low-cost, so it is a typical source of failure for heavily used machines.


To obtain access to the PCB, open the container. If this is the problem, you’ll be able to see exactly where the track has burned away.

We could fix the problem by soldering a thin strip of copper over the burned-up track. To do so, we had to scrape away part of the enameling to get to some decent copper.

A Thermocouple that Has Been Damaged

Inside the milk frother is a small electrical temperature sensor called a thermocouple. It’s used to keep an eye on the Milk temperature and switch it off when the temperature is just right.

This gadget, however, can be damaged or burned out. A faulty thermocouple will notify the controller that the target temperature has been attained before the procedure. The milk frother will turn on, then immediately shut off!


The thermocouple will need to be replaced. A slide connection makes it easy to remove from the PCB. Apply some thermal lubricant to the new one before installing it to ensure that it transmits the temperature correctly.

Electrical Contacts With Dirt 

The Aeroccino milk frother is powered by a spherical plastic connection on the device’s bottom. The milk canister has a female connector, but the Nespresso machine has a male socket. Depending on the type of machine, this can also be a standalone base station.

Grease, muck, and milk residue accumulate in both of these connections, especially if you’re dealing with an overflow.

If the machine won’t turn on or seems to be getting power occasionally, this is likely the problem.


Give the plate a good washing with soap water and clean the contacts with a contact cleaner. You’ll need the following items:

  • Dishcloth
  • Dish soap
  • Isopropyl alcohol or Methylated spirits.
  • A toothbrush or small wire brush.
  • Contact cleaner spray

Start by turning off and disconnecting your computer. Inspect both the connections on the canister and the base station by turning the frother canister upside down.

Scrub vigorously with a tiny brush and a cup of soapy water until you notice the muck has been gone. A toothbrush is ideal for this activity, and we keep one on hand along with our descaling solution and other cleaning supplies. A wire brush may be more appropriate if 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.

Gunk On The Magnetic Whisk

If the milk frother is powered up, the next step is to ensure the milk whisk is functioning correctly.

Over time, milk residue will accumulate on the whisk. This one applies to those who don’t remove the whisk and rinse it between each brew.

The hole in the whisk and the nipple it slips over inside the canister have a minimal tolerance. The whisk will not spin freely if this becomes clogged with muck.


The simple approach is to clean the whisk well using a robust cleaning solution. You’ll need the following items:

  • white vinegar, half a cup
  • 1 tbsp. salt Toothbrush or a little wire brush
  • Combine the salt and vinegar in a glass jar, then lay the whisk inside to soak for a few hours or overnight. Remove the sponge once it has soaked, rinse with clean water, then scrape with the toothbrush to remove any remaining filth.

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

A damaged magnetic whisk

The magnetic whisk attachment can be damaged or broken due to normal wear and tear or a rare unforeseen accident.

The little neodymium magnet falling out and being lost is typical, leaving the whisk unusable.


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

Is Nespresso Frother unfixable? Get yourself a new one.

Things aren’t always worth repairing. If the motor has blown or none of the previous repairs has worked, purchasing a replacement frother may be the best option.

3rd party resellers market new and use complex components on sites like Amazon and eBay, making these relatively easy to come by.

Make sure you obtain the proper one for your computer before you buy.

Nespresso milk frother red lights blinking.

If your Aeroccino’s red light flashes continuously and the heating cycle finishes too soon, it implies your Aeroccino has identified that it is heating up too rapidly.

Due to various circumstances, some of which are listed below with suggested solutions.

Soon after the first use, use the Aeroccino again: If the temperature rises too high, the safety thermostat prevents the Aeroccino from spinning and heating the Milk. In this way, the Aeroccino can be prevented from overheating. Before using it again, it must be washed with cold water, cleaned, and let to cool.

Leaving traces of Milk in the Aeroccino: After each usage, the Aeroccino must be completely cleaned. If there are any traces of Milk within the Aeroccino, it will heat up faster than expected and finish heating and spinning sooner than expected. The button will flash red as a result of this. After each use, we recommend carefully cleaning your Aeroccino with cold water and a Teflon-approved or non-stick scourer. To remove any milk residue on the whisk, it’s a good idea to rinse it.


So, now that you’re aware of all the possible solutions and defaults, if your Nespresso milk frother is not working, put your knowledge to good use!

When operating a coffee machine, 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 coffee while also extending the life of your Nespresso machine.
