CHANGING THE PROGRAM
To change the program in progress, simply open the door and select a
new program. When the door is closed the dishwasher will automatically
select the new program.
DELAYED START (certain models only)
The start of the program can be delayed by 3, 6 or 9 hours.
This allows you to set the dishwasher to work at the times of day most
convenient to you.
After setting the program of your choice, press the DELAYED START
button (6) to select the delay you require. The corresponding DELAYED
START light (7) lights up.
If you wish to exit the procedure without setting delayed start, press the
button in sequence until all three lights are out.
At the end of the cycle, the procedure is automatically deleted, so if you
also require it for the next program you will have to set it again.
"3/1" OPTION BUTTON (on some models only)
(available in all programs except the soak program)
By pressing the button (8) you activate the "3/1" option, confirmed when
the relative light comes on. This option has been studied for the use of
dishwashing powder or tablets with integrated substances in place of
regenerating salt or rinse-aid known on the market as “3 in 1” or “triple
action” products; in this case the dishwasher will use the product in an
optimal way avoiding salt and rinse-aid consumption, which could
already be found in the dishwasher.
Note: When selecting the "3/1" button, it is normal that the salt and
rinse-aid lights remain on, if their containers are empty.
