If the LED status indicator is still blue after you have pushed the cycle 'on/off' button, it means that the mouthpiece is not inserted correctly. Try reinserting the mouthpiece. The mouthpiece should completely enclose the arch of your teeth and the handpiece should be aligned with the center of your face. See tips.
