•
Do not use table salt as it contains insoluble substances which,
over time, may damage the water softening system.
•
When necessary, refill the regenerating salt container before
starting the washing program. In this way, the excess saline
solution will be immediately removed by the water; the prolonged
presence of salt water inside the tank may lead to corrosion.
Be careful not to confuse the salt and detergent packages; adding
detergent to the salt container will damage the water softening system.
ADJUSTING THE WATER SOFTENING SYSTEM
(available in all programs except the soak program)
NOTA: for the setting below to be possible, a washing program other
than the soak program must be set.
Press the PROGRAM DELAY button (8) and keep it pressed until the
preset value appears followed by a full stop (normally 3.). Release the
button then press it again in succession to display the value required,
referring to the table.
The 6 setting levels available will appear in this order:
3., 4., 5., 0., 1., 2..
When the value required appears on the diplay, release the button; after
5 seconds the system automatically returns to setting of the program
delay, and the setting will be made with the chosen value.
N.B.: the display shows the water hardness setting and the program
delay. The dot (.) after the number indicates that the water hardness
setting is being displayed. If the dot (.) does not appear, the program
delay is being displayed.
