Softening the water

Dishwashers require fairly soft water. If the hardness exceeds 6°dH lime scale will form on crockery.  To avoid

this an automatic system adds a special salt to soften the water so that you obtain the best possible cleaning

and drying performance.
To find out the hardness level of your water contact your local water company, or use the enclosed test strip to

measure the water hardness:

Setting the water hardness level for the water softener

Turn on the tap and

let the water run for

about a minute

Remove the test strip

from the packet.

Hold the test strip in

the water for about a

second.

Remove the test strip

from the water and

shake it.

Wait for 1 minute.

The test strip shows

you the hardness

Start/Pause Button begins to flash.

4.Water hardness can be set to the desired level by pressing the 

Program Selection Button 

(Compare the test strip with the Degrees of Hardness Table). The appropriate LED Status 

Indicator lights up.

5.Once you have set the hardness level press the 

Start/Pause Button

 to save the value. The 

Control Indicator on the Start/Pause Button now lights up permanently.

Switch the appliance off again using the 

On/Off

 switch.

If the water hardness level is less than 5 °dH you do not need any special softening

salt. In this case the 'Salt' Control Indicator lights up continually (depending on the

model).

If your local hardness level exceeds 60°dH you should consider getting a water

softening device for your dishwasher.

If you use stream water or rainwater you are recommended to install filters.

If you move do not forget to adjust the water hardness level to suit your new

neighbourhood.
