Flashing green | Flow meter activity detected The rate at which the LED is flashing indicates the flow rate. Nb. At higher flow rates the LED can flash fast enough that it appears as being dimly illuminated. |
Not illuminated / Solid green | No flow meter activity detected Nb. It is normal for a connected grouphead's flow indicator to sometimes remain illuminated when the grouphead is not being used |
Solid red | Incorrect connection to the coffee machine flow meter detected - The polarity (positive and negative) is reversed. Check that the correct type of adaptors have been used for the coffee machine and that the plugs are connected in the correct orientation/polarity |
