Before using for the first time
Water softener
To achieve good cleaning results, the dishwasher needs soft water. Hard water results in calcium deposits on dishware and in the dishwasher.
If your tap water hardness is above 8 gr/gal (values are in US gallons) (140 ppm), the water should be soft- ened. This takes place automatically in the unit’s integrated water softener.
–Your local water authority will be able to advise you of the water hardness level in your area.
–The dishwasher must be pro- grammed to correspond to the water hardness in your area.
–The water softener must be filled with dishwasher salt for reactivation.
If your water hardness is consistently lower than 8 gr/gal (140 ppm), you do not need to add dishwasher salt. How- ever, the dishwasher must still be pro- grammed to correspond to the local water hardness.
Where the water hardness fluctuates e.g. between 9 - 17 gr/gal (160 - 310 ppm), always program the machine to the higher value, 17 gr/gal (310 ppm) in this example.
If there is a fault, it will help the service technician to know the hardness of your local water supply.
^Please note the water hardness: gr/gal
