Quick Colour Guide

The CUBE 4' lights up in blue - and the cup on the display also flashes.

This can happen for a number of reasons:
Often there is simply not enough water in the water tank. The solution: Add more water, then press the cup icon again to continue.
It can also happen if the coffee powder is too fine. In this case, adjust the grinder to a coarser setting.
If the coffee powder is blocking the outlet, you can rinse the Click Cup and clean the system.
If none of this helps, descale the system.

The CUBE 4' lights up in green.

You simply need to change the filter.
