"Empty Drip Tray" Message, But Drip Tray Isn't Full
Cause:
Drip tray was emptied as the appliance was switched off. The amount of water flowing
into the drip tray is registered by the flow meter. When a certain amount is reached,
the "Empty drip tray" message will be displayed. The value for the water amount is
saved when the appliance is switched off; emptying the drip tray after shutoff will not
change this value. See also Section 001-2.5.
Remedy:
Not a fault!
Cause:
Water that would otherwise run into the drip tray was collected in a container instead.
The amount of water flowing into the drip tray is registered by the flow meter. When a
certain amount is reached, the "Empty drip tray" message will be displayed. See also
Section 001-2.5.
Remedy:
Not a fault!

cooled down for the coffee. For cooling, water is pumped through the heater and into
the drip tray.
Remedy:
Not a fault!
