If you are pushing down on the aviators and the NutriBullet is not making any sound, you could have a problem with the outlet. Before you replace anything, try the plug in a different outlet. Still not working? It will be alright. Good thing we have you covered with a replacement guide for a faulty plug.
Try tightening the cup tighter to the base. If it continues to leak, you can easily slide off the rubber seal and replace it with a new one to create a new and lasting seal. If your Magic Bullet NutriBullet continues to leak, see the NutriBullet Leaks problem page for possible causes and solutions.
