Cause
Too low rinsing temperature.
Dishes precleaned too intensely;
sensors therefore decide on weak
wash cycle sequence. Stubborn
soiling cannot be completely
removed.
Too much rinse aid.
No rinse aid added or setting too low. Add rinse aid and check dosage
Detergent residue in the final rinse
wash cycle section. Detergent
dispenser cover blocked by dishes
(cover does not open fully).
Dishes precleaned too intensely;
sensors therefore decide on weak
wash cycle sequence. Stubborn
soiling cannot be completely
removed.
Glasses not dishwasher-proof, only
suitable for dishwasher.
Silverware not adequately rust-
resistant. Knife blades are frequently
more severely affected.
Silverware 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.
Malfunction.

temperature.

food soils.
Increase sensitivity of the sensors.
