on the surface of glass-
ware; film can be wiped

Cause and remedy
The dishes were not loaded correctly.

 Select a more suitable programme (see "Pro-
gramme chart").

ing present.
 Change your detergent.
Items are blocking the path of the spray arms.
 Rearrange the items so that the spray arms can ro-
tate freely.
The filter combination in the base of the wash cabinet
is not clean or is not correctly fitted.
This may have caused the spray arm jets to get
blocked.
 Clean and/or fit the filter combination correctly.
 Clean the spray arm jets if necessary (see "Clean-
ing and care - Cleaning the spray arms").
The non-return valve is open and blocked. Dirty water

aid").
