The dishwasher requires lime free water. Hard water leaves watermarks on your dishes. Your dishwasher
has a special water softening system to remove the hardness of the tap water. Setting this system
correctly will increase the washing effectiveness.
To find out the water hardness level of water in your area, contact your local Water Board or Determine
water hardness level by the help of test strip provided.

If you move to a different location, the level of water hardness will possibly be changed. It is essential to
reset the water hardness in order to obtain optimum washing efficiency.
If the hardness of the water you use is more than 80°dF (French Hardness) or if you are using pit water, we
recommend that you use filters and purifiers.
When your machine is switched off, turn the Programme Knob to position 1.
While keeping the Start/Stop button pressed, switch the machine on by pressing the On/Off button, and release the On/Off
switch.
Press and hold Start/Stop button for 10 seconds.
Last setting will be displayed on the panel of your dishwasher for 5 seconds.
Water hardness level 1 will be shown on the panel, since Program Selection Button is set at that position.
You can set the level of hardness by changing the position of the Programme Knob according to the table given above.
After the hardness setting is selected, save the selected value by pressing the Start/Stop button once more.
Switch the machine off by pressing the On/Off button.
* If your tap water is below 9F (French hardness), you do not need to use special dishwasher salt in your machine. In this case,
salt indicator light will be on continuously.
