Grundfos Eye LED flashing (Bluetooth)

Grundfos Eye LED flashing - Bluetooth connection in progress, but not connecting

Grundfos · MAGNA3 Pumps

What does Grundfos Eye LED flashing (Bluetooth) mean?

When you try to connect your Grundfos MAGNA3 pump to the Grundfos GO Remote app, the center LED of the Grundfos Eye flashes. This means the pump is looking for a Bluetooth connection. If the LED keeps flashing and doesn't become solid, it indicates a problem establishing the connection.

Common Causes

  • Bluetooth is not activated on your smartphone or tablet.
  • Your mobile device is too far from the pump.
  • The connect button on the pump's operating panel was not pressed or activated correctly.
  • A temporary communication issue occurred.
