Three lights flashing next to the Connect button indicate BrilliantPad Smart is not connected to your WiFi network.
Unplug and replug the machine, then wait a minute for the module to try completing its connection. If the three lights continue flashing you will have to re-pair BrilliantPad with your app.
To re-pair, tap the GEAR ICON in the upper right corner of the BrilliantPad Smart App. Then tap Add (+) and follow the instructions in the app.
Upon re-connecting, check for firmware updates and update the firmware, if available.
