When the LED Button is flashing orange, this indicates that your pump either has a poor connection or is completely disconnected from the Byte.
In order to connect the pump, press the pump into the Byte light stand at the pump connection location (to the left of the spout). You should hear a click and the orange light should stop flashing. We recommend using your other hand to create a bit of force into the connection.
Another issue that may be causing poor connection is rust. Check if the connector pins on both the pump and on the neck of the Byte to verify that the pins do not have any rust. If they do, wipe them cleaning using a Q-Tip and rubbing alcohol until all rust is removed from the copper connections.
Now it's time to reconnect the pins of the pump back to the neck. Make sure the water reservoir is securely placed on the stand and the pump pins are aligned with the pin hole on the water reservoir facing the neck of the Byte. Firmly press the pump while holding the neck of the device until you hear an audible 'click'. Please refer to this video on how to remove and reconnect a pump.
