For internal use only
Please note! The process of emptying is influenced by water level measurement limiting
values stipulated in the EEPROM data storage.
10.7 Emptying
The maximum pumping off time during the process of emptying
is monitored. If, after a certain period of time, the water level pin
still detects water, a fault will be indicated.
Fault mechanisms
The pumping-off procedure will be repeated if the water level pin
still recognises water (EEPROM parameter) subsequent to the
emptying time (EEPROM parameter) during the process of
emptying. If, after several pumping-off procedures (EEPROM
parameter) the water level pin still recognises water, the display
will indicate an F8 fault.
In the event of a fault, the appliance control system switches off
all of the actuators and switches over to fault mode. The fault
can be acknowledged with any button. It will, however, re-occur
if the cause of the fault is not rectified.
Please note! The process of emptying is influenced by process parameters of the systems
function “Empty” stipulated in the EEPROM data storage.
Possible causes of faults
• Discharge pump defect or blocked
• Wiring defect (plug connections, cable discontinuity, cable short circuit, etc.)
• Water level gauging disturbed / faulty (water level pin dirty, wiring, bridge between the water level pin
and the earth)
• The water temperature exceeds 70°C
