"Empty dreg drawer" message

"Empty dreg drawer" message:
The following destinations are stored in the diagnosis menu for the message, "Empty dreg
drawer":
• Grounds limit (maximum dregs)
• Actual grounds (dreg counter)
• Grounds warning
Grounds limit is programmed to 13 cycles as standard. The counter "actual grounds" takes
over this value when you empty the dreg drawer and deducts one of these values with each
cycle.
If the value is 0, "Empty dreg drawer" appears (a request of dispensing is no longer
possible). If the last order was a double cup function, the programming allows another 14th
use and then displays "Empty dreg drawer".
If the counter "actual grounds" reaches a value of "grounds warning" during the process
(e.g. "3"), the advanced notice "Empty dreg drawer" appears on appliances with a display
(coffee can still be dispensed).
When the dreg drawer is emptied, the counter "actual grounds" will be reseted (after 5
seconds).

04 FUNCTIONAL PRINCIPLES
"Empty residual water tray" message
Function:
The residual water level is monitored using a
capacitive sensor. The sensor is positioned approx.
half way up the upper edge of the residual water
tray. To ensure the best possible use of holding
capacity, the sensor is positioned in the area of a
shaft where its upper edge overlaps the sensor.
Therefore, the residual water tray fi lls up to the
Sensor
upper edge of the shaft and the overfl ow in the
shaft triggers the sensor and therefore displays to
empty residual water tray.
Exception:
Odea: from 2008 production, the Odea series is no
longer fi tted with a residual water sensor.
The capacity is calculated by the electronics,
depending on the dispensing situation (coffee,
steam, hot water, rinsing).
