The Nespresso Aeroccino 4 milk frother is a fully digital milk foaming machine for coffee lovers.

However, being an electrical device, anything can go wrong at any time. 

That is why we thought, why not answer questions with issues like my Nespresso Aeroccino 4 not working or any other issues? Here are the reasons why is your Nespresso Aeroccino 4 not working –

1. Broken heating element

The heating element is a crucial part of a milk frother as it helps heat the milk to a certain temperature to make foam. However, if the part is not working, you can easily know that the liquid will not heat up or the device will not work. 

So, to fix that issue, you will have to access the PCB and repair any broken or burnt-out copper layer leading to the heating element. 

2. The magnetic whisk is broken or lost.

Sometimes the magnetic whisk breaks, or you accidentally damage the part for any reason. Moreover, the small neodymium magnet inside the whisk can fall out, making the piece useless. 

The easiest option is to get a new whisk, as the Nespresso Aeroccino 4 parts are easily available from their website or other third-party sites. 

3. The thermocouple issues

Nespresso Aeroccino 4 Not Frothing!

Making foam is the only reason why people buy a milk frothing machine. If that appliance fails to serve that particular purpose, what is the point of spending that money on a milk-frothing machine? 

Here are some reasons why your Nespresso Aeroccino 4 is not frothing properly or at its original speed –

Problem	Solution
Dirty parts	Before using the appliance, rinse it as residue from your previous use can build up inside. from foaming, rinse with cold water and dry it for a while. That will prevent the device from foaming the milk.
Milk quality	Using UHT milk will allow you to make a consistent foam; however, low-quality milk takes longer to create foam.
Too much liquid in the jug	Overflowing the milk jug will not allow the whisk to properly and efficiently froth, So make sure that the amount of liquid you put in stays under the first line of the jug. Moreover, you can also use the second line as a reference if you are making a latte.

Nespresso Aeroccino 4 Not Spinning!

The whisk on the appliance spins the liquid in the jug and makes the foam. If the whisk does not spin, then there will be no foam from the milk for your coffee. So, why does that happen?

It can be because the magnet of the whisk is broken, lost, or faulty. In that case, the best option is to get another whisk. However, if the machine is in its warranty period, you can take it in for repairs. 

Another reason is leftover or burnt milk residue in the whisk. Milk residue from your previous use can build up and prevent the heat from getting through the liquid, and in that case, even a whisk will not be able to make foam. So, clean the appliance after every use. 

Nespresso Aeroccino 4 Not Hot Enough!

If your Nespresso Aeroccino 4 is not hot, it could be because of a faulty heating element. That part of the appliance allows the device to get hot and transfer that heat to the liquid in the jug so that the milk reaches a certain temp where the whisk can easily froth it. 

However, the heating element is connected to a circuit board with thin layers of copper, which can burn out at any time. One solution is to open and access the PCB and re-soldier the copper layer. If that does not work, then replace the machine. 

Another reason why your frothing machine is not hot enough is the thermocouple. There is no option but to change that part. Moreover, milk residue can also prevent heat from passing through the liquid. So, clean the whisk, jug, and other parts after every use. 

Nespresso Aeroccino 4 Not Heating Milk!

The heating element and milk residue are the main two reasons why your Aericcino 4 is not heating milk. These two are the most common issues regarding a milk frother not heating the liquid. 

The heating element is crucial as it heats the milk in the jug and allows it to reach a certain temperature where you can easily make delicious foam. However, if that stops working, the milk will not heat up, and you will not be able to create foam.

So, to resolve that, access the PCB and look for any burnt-out connection. Replace or soldier another layer of copper, and you should be good to go.

Another reason could be leftover milk residue or burnt milk residue. The residue from your previous use creates a thick layer that prevents heat from going through and heats the liquid. That is why we recommend following the Nespresso Aeroccino 4 instructions on properly cleaning your appliance after every use. 

Nespresso Aeroccino 4 Heating But Not Frothing!

If your Nespresso Aeroccino 4 is heating up but not frothing, then either the whisk is faulty or the type of milk you are using is not suitable for making foam. In most cases, milk is not meant for making froth. 

The whisk can also go bad or break, and in that case, changing it is the best option. However, if the milk you are using has low protein and fat content, it will be much harder to froth, and it might not even make foam.

Moreover, more protein or casein also makes it harder to froth. That is why choosing your milk product is very important. 

Nespresso Aeroccino 4 Not Turning On!

1. Faulty electrical system

Check your power outlet and check if the power cable is properly in the socket. In most cases, it is the cable sticking out of the power socket preventing the machine from turning on. Moreover, ensure the voltage is also what the manufacturers recommend. 

2. Faulty parts

If the issue is not with the power socket or the cable, it is probably some internal problem, such as a faulty part or a burnt-out circuit. The best option to choose in that situation is to contact support and take it in for repairs. 

3. Dirty connections

It is common for a kitchen appliance to get dirty and build up gunk in its connections. We recommend taking a small brush and cleaning any dirt, gunk, and debris areas.
