• The indicators and are off.
• The indicator continues to flash.
• The display shows the current setting: e.g. = level 5.

10 you will start again from level 1.
3. Press the on/off button to confirm the setting.
If you use multi-tablets containing salt and the hardness of your water is lower than 21°dH,
you can set the lowest water softener level. It deactivates the salt refill indicator.
If you use standard detergent or multitablets without salt, set the proper water hardness level
to keep the salt refill indicator active.
