gramme. Some stubborn soiling cannot be
completely removed.
Too much rinse aid
No rinse aid in the appliance or setting too
low
Detergent residue in the final rinse. Deter-
gent dispenser cover is blocked by utensils
(cover does not open fully)
The drain check valve is not tight
Utensils were precleaned too vigorously;
sensors therefore decide on a gentler pro-
gramme. Some stubborn soiling cannot be
