FILLING SEQUENCE (with Virtual Sensors)

Once a program has been started, the first action of the dishwasher will be to drain down until the 

“D-Sensor” 

registers

 empty + 15 seconds

Thereafter, the W-Sensor runs for 40 seconds at  1400 rpm with the bottom delivery outlet open, to 
confirm that the tub is actually empty  (if not, after three unsuccessful attempts error 

“F15”

 will be 

displayed). 
The machine then starts to fill — an operation that will be completed in two steps:

1.

Static fill: 

the fill solenoid valve is piloted to open by the Main Module, and will admit 

approximately 2.0 litres of water, measured by the Water Turbine. When this threshold is reached, 
the Wash Pump (

“W-Sensor”) 

runs at 1400 rpm with the bottom delivery outlet open, to confirm 

whether or not the machine is in Full status. If the 

Full

 condition is satisfied, the dynamic fill will 

start.

Note: 

The BLAC Wash Pump Motor running at 1400 rpm on the bottom outlet, full status will 

register with approximately 1.5 litres of water.

2.

Dynamic Fill:

 with the BLAC Wash Pump running (at 1400 rpm, bottom delivery outlet), the fill  

solenoid valve is activated and held open by the Main Module until the water level increases to  
around 3.5/3.8 litres (depending on the cycle selected). 
If full status is confirmed by the “W-Sensor”, the machine will continue washing as normal.

Possible Filling/Draining Errors

Machine is not emptying

Once a program has been started, the first action of the dishwasher will be to drain  until the "D-Sensor" 
registers empty + 15 seconds. Thereafter, the "W-Sensor" runs for 40 seconds at 1400 rpm with the 
bottom delivery outlet open, to confirm that the tub is actually empty (if not, after three unsuccessful 
attempts error "15" will be displayed). 
The machine then starts to fill - an operation that will be completed in two steps: 

Machine's inlet Water Tap is OFF.

Static fill: 

The fill solenoid is piloted to open. The Main Module doesn't receive any information from 

the Turbine (because no water in entering the machine). After a short time the machine will bleep time 
and H will be displayed, is displayed (Warning to the user that no water is entering the machine) after 
a further period the machine  times out and 06 fault will display. 

Turbine out of Range

Static fill: 

The fill solenoid is piloted to open. The Main Module does not receive any information from 

the Litre-count turbine. After one minute during which the solenoid valve remains open and 
approximately 2.4 litres of water have entered the machine, the Wash Pump (W-Sensor) runs at 1400 
rpm with the bottom delivery outlet open to confirm 
W-Sensor Full status. The cycle moves on to dynamic fill.

Dynamic fill: 

The speed of the Wash Pump is increased to 2400/2500 rpm (depending on the cycle 

selected) and the tub continues to fill until the motor torque registers at a value corresponding to Full 
status, at which point the machine continues washing as normal.
