Not frothing I have semi skimmed milk delivered to my door daily by the dairy. I have always used this milk with my aeroccino and had no problems at all. 1 week ago it stooped frothing the milk. I have tried using other milk from the local supermarket and have the same problem. The aeorccino has been cleaned scrupulously.

SOURCE: not making froth

Had the same problem, but called Nespresso. Their tech suggested the following: 1) always leave off the base - will stay on even if button not pressed 2) invert the Aerocinno for 24-48 hours to "reset" the thermostat in the device. I began leaving the base plugged in, but immediately after using and cleaning (don't get ANY water in the bottom of the machine!), I invert the Aeroccino and leave it that way. My machine began making great froth with any tyoe of milk, and continues to do so a month later -

Sounded crazy to me initially, but it works.....Never returned the device, and no need to do so now - Good luck!

SOURCE: aeroccino deosn't make froth

Our aeroccino worked fine for 2 years and suddenly it didn't made foam anymore. We tried the "inverting trick" without much success. We contacted Nespresso and they suggested switching from regular fresh milk (we used 2%) to UHT milk (harder to find in US) and to use it cold and freshly opened. So we tried that and it works.
Hope this solution works for you too

SOURCE: Nepresso aeroccino doesn't spin fast enough to froth the milk

The company will tell you to turn upside down for 24 hours to reset. I did this but it did not work. Try turning upside for aeroccino upside down for 24 hr. You do not need to do this to the base. They told me if this does not work, I need to buy a new one. I hope you have better luck. I am on my third one. you may be covered under warranty- call Nepresso soon..they cover them for about 1 year. Good luck

SOURCE: Aeroccino frother won't turn back on after we get some froth and still more milk in container.. takes a long time to be able to activate again.. using Almond milk could be the problem any suggeest

My Nespresso Aeroccino often would not heat or froth multiple times after one use. I called Nespresso, they have excellent customer service, and was told to rise the inside (careful not to get the outside button or electric elements wet) of the Aeroccino with cold water a few times and to retry. Works like a charm!
The customer service is the best I have encountered in a long while, give them a call, it will make your day they are so pleasant and helpful!
