Nespresso Frother Blinking Red? This Is What It Means

If the red light on your Nespresso Aeroccino milk frother is blinking continuously, it means that there is a machine error. But what exactly caused the error? How do you fix it so you can get back to making cappuccinos and lattes? There are a five possible reasons why your machine is not frothing.

Reason #1: Back To Back Uses Of The Aeroccino

If you frothed milk for a drink and then immediately tried to use the Aeroccino again to froth milk for another one, it is possible that your machine has overheated. The Aeroccino has an internal thermostat that will stop the frother from operating if the temperature gets too high. This feature is a safety precaution to prevent it from burning out.

To fix this, wait 15-20 minutes for it to cool down. If you need to use it immediately, you can also rinse the jug and the lid with cold water to cool it down. Just be sure to not get the base with electrical parts wet.

Reason #2: Aeroccino Not Cleaned Properly

The user manual says you need to clean your frother after each use. If you haven’t been doing this, it is possible that milk residue is left inside the Aeroccino. This is most common at the bottom of the jug. This residue will cause the frother to heat up faster than it should, which will trigger the thermostat and stop the machine from operating.

Try cleaning the jug with cold water and a sponge or scouring pad that is safe for nonstick cookware. If you have the Aeroccino 3, make sure to wash by hand because it is not dishwasher safe. You should also thoroughly clean the whisk to remove any milk residue left on it after each use.

Reason #3: Missing or Broken Whisk

Depending on when you purchased your Aeroccino, you’ll either have two separate whisks or one that combines the ring with the coil. Either way, you need to make sure there is a whisk in your machine otherwise it won’t froth. If you lost your whisk, you can get a model 3 replacement or a model 4 replacement.

Reason #4: Not Enough Milk

Be sure you fill your frother to one of the two max lines. It is recommended that you use cold whole or reduced fat milk.

Reason #5: Loose Connection

Make sure that the whisk is securely attached to the jug. Then ensure that the jug is securely positioned onto the base. Make sure the connectors at the bottom of the jug and the top of the base look clean. If you’ve tried everything else, you may want to try to hold the jug firmly on the base and then push the button to start the machine.

Is Your Nespresso Frother Still Blinking Red?

If you’ve tried all of these steps and your Nespresso frother is still blinking red, you should call Nespresso support. The toll free number is 1-800-562-1465. If they can’t help, you may need to consider buying a new Aeroccino. There are two models currently on the market – the Aeroccino 3 and Aeroccino 4. The fourth generation has some new features that you may find valuable.
