mmol/l.
3in1 detergent or bio/eco
detergent not effective enough.
Underdosing of detergent.
Too weak rinse programme
selected.
Too low rinsing temperature.
Too little or unsuitable detergent. Use suitable detergent at correct dosage.
Utensils precleaned too intensely;
sensors therefore decide on
weak programme sequence.
Stubborn soiling cannot be
completely removed.
Film formation consisting of
ingredients from vegetables (e.g.
cabbage, celery, potatoes,
noodles, ...) or the tap water (e.g.
manganese).

the service life of the dishwasher.
Remedial action
