(models with salt container)
• Food leftovers are staying on the
dishes for too long.
• The machine is not grounded
properly.
• Cutlery parts from low-grade
rust-free steel.
• Dish items with rust stains.
Milky appearance or rainbow on the
glasses (glass corrosion)
How to fix these problems
• Add a smaller amount of detergent.
• Compare the water hardness level setting on the
dishwasher against the stated values from the
local water supplier.
• When water hardness is low (below 7 American
degree of hardness or 106 parts per million), do
not use salt even if your dishwasher has a water
softener.
• Use a lower phosphate content detergent.
Rust stains, destruction of the
surface
How to fix these problems
• Salt can destroy metal surfaces and cause rust
damage.
• Check whether the lid of the salt container is
firmly closed. Use the funnel to pour in special
salt. Begin the Rinse and Hold program right after
filling in salt. After the program is complete, check
whether the lid may have loosened.
• Remove coarse dirt under running water and
carry out the Rinse and Hold program every 2
days without detergent.
• Check the grounding of the system. Static
electricity may eat holes into metal and cause
irreparable damages to surfaces.
• Rust on such items cannot be avoided. Cutlery
or dishes of this type are not suited for the
dishwasher.
• Rusty dishes may "infect" other items. Cutlery
or dishes of this type are not suited for the
dishwasher.
