One of the many attributes that makes coffee so wonderful is its versatility. Irrespective of your preference, there’s usually a way you can tailor a cup of coffee to suit your taste.
If you’ve got a bit of a sweet tooth or aren’t a huge fan of the undiluted flavor of black coffee, you can spice things up by adding some milk and sugar.
You can even be super creative and decide to make a delicious latte or cappuccino. After all, several Nespresso models are fully equipped with milk frothers that can help you achieve this.
Your plans could get thrown out of the window in a split second if your Nespresso milk frother suddenly starts blinking red.
Once the milk frother blinks red, it means an error or problem is preventing it from performing as expected.
We’ve got your back. This post explains why your Nespresso milk frother keeps flashing red and how you can easily fix this issue. Let’s get started!

Your Nespresso milk frother is designed to produce frothed milk to help spice up your coffee. However, once it begins to blink red, it means there’s a problem you need to solve. You can fix this by cleaning the frother, checking the milk level, reattaching the whisk, and allowing the frother to cool.
1. Cleaning Your Nespresso Milk Frother
It’s important to understand that you need to clean and maintain your frother as frequently as you use it.
After using your milk frother and utilizing the frothed milk it delivers, there will be milk residues at the bottom of the jug.
This means that the residues will remain in the jug if the frother isn’t washed after use.
After a while:
The milk residues left from previous use will accumulate in the frother and cause the machine to overheat. Also, it affects the quality and hygiene of frothed milk.
Here’s what happens:
Your frother is designed with a temperature sensor as an extra safety measure.
As soon as the sensor realizes the temperature in the frother is much higher than it should be, the system automatically shuts down and sends an alarm by flashing a red light.
The only way to stop the milk frother from blinking red is by removing milk residues at the bottom of the jug.
This is achieved by cleaning your Nespresso Milk Frother. You’ll need cold water and a non-abrasive sponge.
You can clean your milk frother by following the steps below:
- Step 1: Turn off your Nespresso Milk Frother.
- Step 2: Remove the jug from the base.
- Step 3: Carefully detach the whisk from the machine.
- Step 4: Remove the protective seal from the top of the lid.
- Step 5: Rinse the whisk, seal, and lid of the frother.
- Step 6: Use a non-abrasive sponge to clean the machine’s insides.
- Step 7: Rinse the inside with cold water.
- Step 8: Dry all parts with a soft cloth.
- Step 9: Reassemble the machine.
While washing the insides of older models like Nespresso 3192 or Aeroccino 3, you must be careful not to submerge it as this could damage your milk frother.
Once you’ve cleaned your milk frother, there won’t be any residues left in the jug that will cause the machine to overheat. Your milk frother should stop blinking red after this.
2. Checking The Milk Level
Whenever you’d like to use your Nespresso coffee maker, it’s advisable to fill the water reservoir first before you start brewing.
This is because your water reservoir could dry up during brewing, leading to problems preventing it from brewing hot coffee.
You need to ensure your milk frother has enough milk before you use it to make frothed milk.
You would only like to add the exact quantity of milk you need to avoid wastage. Thus, the size of the drink you’re making affects the amount of milk you’ll add.
Your Nespresso Milk Frother must be filled with a certain amount of milk to work effectively.
There are two maximum levels on the frother. The machine will blink red if the milk level in the frother is below the two max levels.
You must always fill up to any of the two maximum levels.
If you’re making smaller drinks or using a frother with a coil ring, fill to the lower maximum level.
This is done to avoid wastage and prevent the frother with a coil ring from overflowing.
On the other hand:
If you’re making bigger drinks or using a frother without a coil ring, fill to the upper maximum level.
3. Reattaching The Whisk
Here’s the thing:
After washing and drying your Nespresso Milk Frother, you’re expected to reassemble the components and store for later use.
It’s easy to get carried away while assembling and forget to attach some components or even place them improperly, especially with components like the whisk, which is really small.
The next time you try to use the milk frother, the whisk might be missing or wrongly placed. If you try to use it, it will immediately send warning signals by blinking red.
Once you realize it’s blinking red, you must first confirm that the whisk is present and in its rightful position. To do this, follow these instructions:
- Step 1: Turn off the milk frother and wait for it to cool.
- Step 2: Empty the jug.
- Step 3: Check the bottom of the frother for the whisk and ensure it’s properly connected to the base.
If you discover your whisk is missing, don’t fret. You can easily obtain a replacement that will be compatible with your frother. Call Keurig Customer Service to get you started.
In any case:
Once you’ve placed all components in the right position, your milk frother should stop blinking red.
4. Allowing The Milk Frother To Cool
As we’ve explained, your Nespresso Milk Frother sends error signals by blinking red when it’s overheating or if the components are not properly placed.
Your frother will overheat if milk residues are still stuck inside or used continuously without any breaks that allow it to cool down.
As you’ve seen:
You can easily eliminate the milk residues by cleaning after each use. Although this might not always be possible if you have to use it to make multiple drinks within a short time.
If you need to operate your milk frother continuously, you’ll need to cool it down after each use to prevent it from overheating.
You can achieve this by switching off the frother, detaching the jug from the base, and waiting for a few minutes for it to cool before turning it back on.
All Nespresso Milk Frother models only blink red to signify that there’s an issue the operator needs to tackle immediately.
This issue can arise if the machine is overheating, has an improperly placed whisk, or if there’s insufficient milk. All models are likely to blink red from time to time.
The following models are more liable to experience the issues that cause them to flash red:
1. Nespresso 3192
All in all:
The Nespresso 3192, also called the Nespresso Aeroccino Plus, is an older model of milk frothers designed by Nespresso.
It heats liquid milk silently and produces frothed milk with a nice creamy flavor.
It received great reviews from customers for its efficiency and quality, it is no longer being manufactured by Nespresso.
This is because newer and more improved versions like Aeroccino 3 and 4 are being produced.
The Nespresso 3192 doesn’t have a separate compartment where you can store the whisk after cleaning.
This means that once you finish cleaning, you’ll have to put the whisk back into the jug.
It’s very easy to misplace the whisk while assembling which causes problems the next time you try to use it.
2. Nespresso Aeroccino 3
The Nespresso Aeroccino 3 is of the newer Aeroccino models designed by Nespresso. It has a whisk with a removable spring and is constructed with plastic and stainless steel.
It’s a fantastic model as it is sleek, noiseless, and super easy to use. It heats milk quickly and is capable of making both hot and cold froth.
It has a few cons. It doesn’t have a handle which means you can only grip the body to hold it. It doesn’t have a pouring spout, so you can’t make fancy latte art with it.
It can only be hand-washed and must never be submerged in water during cleaning, as it can become damaged and start blinking red the next time you try to use it.
With careful hand washing, drying, and our simple remedies, you can easily fix its issues and stop the error signals.
In a nutshell:
The Nespresso Milk Frother models were designed to make frothed milk in the quickest and most noiseless way possible.
