Sonicare App update
Ensure that you have the latest version of the Sonicare App installed on your smartphone.
Smartphone software update
Check to see if you have the latest operating system running on your smartphone:

• Philips Sonicare DiamondClean Smart

Turn on your toothbrush by either removing it from the charger or pressing the mode button. The lights on the handle will illuminate to tell you that your toothbrush is turned on.

If this is a new toothbrush, and your first time trying to connect to the app, ensure that the toothbrush handle is fully charged. 

Check to see if the Bluetooth on your smartphone is turned on before opening the Sonicare App. If not, go to the settings on your smartphone to turn on Bluetooth.
