Step 1. Checking your water hardness level

Hardness setting
BEFORE USING FOR THE FIRST TIME
In order to provide satisfactory rinsing results, the dishwasher requires soft water, i.e., containing
little or no lime, otherwise water stains will be left behind on the dishes and interior containers.
If the tap water exceeds a certain level of hardness, it must be softened, i.e., decalcified.
This is achieved by adding a special salt to the water softener inside the dishwasher.
The required amount of salt is set up according to how hard your tap water is.
This model has a water softener to soften hard water.
Please read these notes carefully for correct operation.
