5 Reasons Nespresso Frother Not Working Flashing Red

A flashing red light on your Nespresso Aeroccino milk frother indicates that the machine has detected an error. However, this is not always a cause for concern. The red flashing light is actually a safety feature that stops the machine from operating incorrectly during times of need. Also, you’ll notice that the Aeroccino isn’t frothing as it used to. Here’s how to fix your Nespresso frother blinking red light.

Why Nespresso Frother Blinking Red and Not Working [Reasons & Fixes]

The red light will stay on, but the machine will not be able to froth milk. Fixing the milk frother error is easy and can be done in a few minutes. Here are some causes and fixes you can take to determine what might be wrong with this.

1. Whisk Damaged

The reason why your Nespresso Milk Frother keeps on flashing red light might be that there’s an issue with the whisk inside. Remove it from your machine and inspect it carefully. If there are any cracks or breaks in it, simply order a new one. Aeroccino 3 and Aeroccino 4 whisks are easily available online.

2. Loose Power Supply

All Nespresso coffee makers with frothers require a good electrical supply in order to function properly. Place the frother properly on the base. Make sure the base is undamaged with plastic melting or it overheating. As well, if there is any crusty build-up on-base connector, you should clean it off with a brush and a scrubbing sponge.

Moreover, If you have other appliances on your same power strip, make sure they are unplugged before using them. There is also a reason why it’s recommended that you plug your machine directly into an outlet rather than use an extension cord. If you are using an extension cord, try moving your machine closer to where it’s plugged in and see if that fixes your blinking red light problem.

3. Milk Level Too Low

If the milk jug is too low or empty, the red light will start to flash. To fix this, simply add more milk to the milk jug. Make sure the milk is at least up to the lower MAX level for frothy milk, or the upper MAX level for lattes. Once the milk has been added, check if the red light stops flashing. If it does, then your problem is solved. If not, continue reading for more troubleshooting tips.

4. Not Cleaned Properly

Proper cleaning is essential for your milk frother to work correctly and efficiently. If your Nespresso milk frother is not working properly, it may be due to improper cleaning. Most users simply rinse off their milk frothers.

The key to getting your machine back up and running is making sure that all of its components are cleaned correctly and regularly. The process begins by unplugging the appliance from its power source before disassembling all of its parts. Next, each part should be thoroughly washed in hot water with mild soap or specially formulated cleaning agents designed for use with coffee machines. Once rinsed off, they should then be dried with a soft cloth before being reassembled into the machine.

5. Damaged Motor

If you think the motor of your Nespresso Milk Frother may have been damaged, there are a few things you can do to check. If you dropped your frother or ran it in water, there’s a good chance the motor has been affected. You can try taking the frother apart and gently cleaning each part with a damp cloth or soft brush.

If this doesn’t improve the performance of your frother, then the motor may have been damaged beyond repair. If that’s the case, you’ll need to order a new one.

Why is Nespresso Aeroccino Not Frothing Well?

No matter what is wrong with your Nespresso Aeroccino, fixing it as soon as possible is important. Basically, if your Nespresso milk frother was not working well or had no flashing light, the most likely cause is that the frother jug or whisk is not cleaned well.

One thing to remember is that the Aeroccino only produces froth if a whisk with a coil is used. If you’re using a whisk without a coil, then it won’t produce much of anything. Another thing is that try to add fresh milk at any time because the protein properties of the milk might deteriorate, so it won’t foam as well.

Bottom Line

A blinking red light on your Nespresso milk frother doesn’t necessarily mean you have a defective unit. Sometimes, it can be due to other factors, such as an incompatible refill or a setting that needs adjustment. Whatever is causing your milk frother’s red light to blink, I hope you find my troubleshooting guide helpful.
