Preparing the washing cycle
How much washing powder and fabric softener?
The amount to be used depends on
•the load:
If the washing powder producer does not make any specifications for small loads, use a third less for half loads, and for very small loads only use half of the amount of washing powder recommended for a full load.
•the degree of soiling of the washing:
For only slightly soiled washing use less washing powder. Follow the instructions of the washing powder producer and load.
•on the degree of hardness of the tap water:
The harder the water, the higher the dosage! You will find the quanti- ties to use according to water hardness on the washing powder pack- aging.
Liquid detergent
Add liquid detergent using the dosing device provided by the detergent industry. Please follow the instructions on the package.
Using a water softener
For a medium to high degree of water hardness (from water hardness area II) water softener should be used. Follow the manufacturers instructions! Then always dose detergent for hardness area I (= soft). You can find information about the local degree of water hardness from your water utility.
2 As the water softener has to be added before the main detergent (pre- softening of the water), 80% of the water softener otherwise needed is sufficient.
