Prerequisite:
•
Water softening system has been activated.
•
There is salt in the appliance.
•
At least one programme has been run since it was refilled (e.g. pre-rinse)
5.13.1
Measuring the water hardness
1. Start the test programme.
2. Run through the test programme as far as the visual check of ‘water level in
appliance’ (the body of the pump is full of water).
3. Take a sample of the washing water and perform the hardness test.
4.
0
If the hardness of the washing water is between 1 °dH and 6 °dH,
► make no adjustment.
5.
0
If the hardness of the washing water is higher than 6 °dH,
1) check the activation of the water softening system.
2) Check that the correct hardness is specified (See Changing customer
settings).
3) Use fresh detergent or tab.
5.13.2
Measuring the water hardness while the water
softening system is turned off
Salt substitutes in detergents can bind calcium and magnesium
ions in the water up to 21 °dH.
Observe the information given by the detergent manufacturer.
1. Take a sample of tap water and perform the hardness test.
2.
0
If the hardness of the tap water is less than 21 °dH,
► use a suitable detergent with salt function.
3.
0
If the hardness of the tap water is higher than 21 °dH,
1) activate the water-softening system.
2) Check that the correct hardness is set up.
3) Check the level in the regeneration container.
4) Use fresh detergent or tab.
