6.14  Regeneration levels 

 
The counter for execution of the “Ad Hoc” regeneration process is governed by the electronic control system 
on the basis of the duration of the fill phases (i.e. the quantity of water introduced), and NOT on the number 
of cycles. 
Regeneration can be set to one of 10 levels. If regeneration is set to level [

1

], the procedure is not performed 

and the Salt LED remains unlit. 

6.14.1  Setting the regeneration level  

 
 
 
 
 
 
 
 
 
 
1.  Cancel any cycles that may have been selected. 
2.  Press key 

S0

 to switch the appliance on. 

3.  Press buttons 

S2-S3

 simultaneously, and hold down until LEDs LD1, LD2 and LD3 begin to flash. 

 
 
 
 
 
 
 
 
 
 
 
4.  Press button 

S1

: LEDs LD2, LD3 switch off, while LD1 continues to flash. 

  The regeneration level is shown by the display [ 

5L

 ]. 

5.  Press button 

S1

 sequentially to modify the level of regeneration. 

  Each time the button is pressed, the regeneration level increases by 1 level. If 

S1

 is pressed after the 

10

th

 level has been reached, the setting returns to level 1. [

..... 10L

 ] 

6.  To store this setting in memory: press button 

S0

 and switch the appliance off; alternatively, wait for 60 

seconds (selection mode) 

 

6.14.2  “Blending” function 

This function is performed inside the fill tank during the water fill phase which, depending on the position of 
the selector, automatically blends the softened water with the unsoftened water present in the appliance. 
In practice, the softened water is introduced into the appliance through the softening system, while the 
unsoftened water flows via an open by-pass duct directly through the steam venting ring. 
If the level of regeneration is set to between 

1

 and 

4

, it is advisable to activate the BLENDING function to 

mix softened water with unsoftened water. 
This function optimizes the consumption of salt thus preventing the possibility of corrosion of glass recipients 
due to excessively soft water. 
When the BLENDING function is activated, the percentage of unsoftened 
water introduced into the dishwasher is 

15%.

 

The BLENDING function is activated using the selector knob located inside 
the tub, on the left side, in the vicinity of the steam venting grille.
