Removable streaks are
present on glasses, glass-
ware with a metallic appear-
ance and cutlery.

Tableware has been pre-
cleaned too intensely. The
sensors chose a weaker pro-
gramme. Stubborn soiling
cannot be entirely removed.

Only remove large remnants of food
and do not prerinse tableware.

Irreversible clouding of
glassware.

Glasses are not dishwasher-
proof, only suitable for dish-
washers.

Use dishwasher-proof glasses.
Glasses are usually only suitable for
use in a dishwasher, i.e. long-term
wear or long-term changes must be
expected.

Avoid a lengthy steam phase
(standing time after wash cycle
ends).

Use a programme with a lower tem-
perature.

"Programmes", Page 18

Set the softening system to the wa-
ter hardness.

Use detergent with a glass protec-
tion component.

Rust spots on cutlery.

Cutlery is not sufficiently
rust-resistant. Knife blades
are often more severely af-
fected.

Use rust-resistant tableware.

Cutlery may also rust if
washed together with rust-
ing items.

Do not wash rusting items.

Salt content in washing wa-
ter is too high.

1.

Remove any spilled special salt
from the tub.

2.

Screw the cap of the special salt
dispenser on tight.

Detergent residue is present
in the detergent dispenser
or the tablet collecting tray.

Spray arms were blocked by
tableware so detergent was
not rinsed out.

Check that the spray arms are not
blocked and can rotate freely.

Detergent dispenser was
damp when detergent was
added.

Only add detergent to a detergent
dispenser when dry.

Excessive formation of foam
occurs.

Hand washing-up liquid is
present in dispenser for
rinse aid.

Immediately add rinse aid to the
dispenser.
