Nutri-Bullet Blender stucks due to some problems in activators slots. To correct this problem, you need to have a few drops of vinegar, oil or warm water. Initiate by putting the warm water into the activated slot. If it’s not available with you, then go with putting drops of vinegar or oil in it. Press it down with the use of a spoon or something which you think is suitable for it. Never go with your fingers to press the activator. Release it after some time, and now your blender will be working again.
