Cause
Too low rinsing temperature.
Utensils precleaned too intensely;
sensors therefore decide on
weak programme sequence.
Stubborn soiling cannot be
completely removed.
Too much rinse aid.
No rinse aid added or setting too
low.
Detergent residue in the final
rinse programme section.
Detergent dispenser cover
blocked by utensils (cover does
not open fully).
Utensils precleaned too intensely;
sensors therefore decide on
weak programme sequence.
Stubborn soiling cannot be
completely removed.
Glasses not dishwasher-proof,
only suitable for dishwasher.
Cutlery not adequately
rust-resistant. Knife blades are
frequently more severely
affected.
Cutlery will also rust if rusting
parts are rinsed at the same time
(pan handles, damaged utensil
baskets, etc.).
Salt content in the rinsing water
too high, as salt dispenser lock
not fastened firmly or salt was
spilled while being refilled.
Remedial action
Select programme with higher washing
temperature.
Do not prerinse utensils. Remove only
large food remnants.
Increase sensitivity of the sensors.

Detergent dispenser cover must not be
obstructed by utensils.
Do not place utensils or fragrance
dispenser in the tablet collecting tray.
