– Is there still special salt in the salt container? Without special salt, the water will
not be softened. At water hardnesses above 4 °d, lime deposits will form on
your dishes (see the section on "Filling with special dishwasher salt").
– Have you set the water softener to the local water hardness? (see the section
on "Setting the water softening system").
The dishes do not dry and have no sparkle.
– Have you used a branded rinse aid?
– Is there sufficient rinse aid in the dispenser? (see the section on "Filling with
rinse aid").
Glasses and dishes have streaks, stripes, milky blotches, or blue-
coloured blooms.
– The rinse aid is being overdosed. Set a lower rinse aid dosage (see the section
on "Setting the rinse aid quantity to be dosed").
Glasses and dishes have dried-on water drops.
– The rinse aid is being underdosed. Set a higher rinse aid dosage (see the section
on "Setting the rinse aid quantity to be dosed").
– The detergent may be the cause. Contact your detergent manufacturer's con-
sumer services manager.
Rust marks can be seen inside your machine.
– The dishwasher interior is made of stainless steel. If rust is found inside your
dishwasher, this must be from another source (rust in water, from saucepans,
cutlery, etc.). Remove such marks with a commercially available stainless steel
cleaner.
– Have you dosed the detergent correctly? (see the section on "Filling with
detergent").
– Is the lid of the salt container closed properly? (see the section on "Filling with
special dishwasher salt").
– Have you set the water softener correctly? (see the section on "Setting the
water softening system").
Whistling noise during the dishwashing cycle.
– You may possibly need to seek a remedy by using another branded detergent.
The whistling is completely harmless.
