4.2.8 Checking the wash result
The dishware should be checked after each wash for:
PROBLEM CAUSES & MEASURES
Starch spots • Scraping: Important to remove as much food particles as possible
before washing. This also means that the water in the machine
does not need to be changed as often. Scrape better.
• Detergent and drying agent dosage: If using liquid detergent and
drying agent, the same make and type should be used. The dosing
affects both detergent and drying results of the dishware. The hard-
ness level of the water affects the consumption of detergent. Con-
tact your detergent supplier.
• Temperatures: At incorrect temperatures the dishes will not be
clean. Contact a service technician if you need to change the set
values.
• Program selection: Program with too short a washing time select-
ed. Choose a program with a longer washing time.
• Cleaning the machine: Insufficient cleaning of the machine af-
fects the results of the washing. Ensure better cleaning of the ma-
chine.
• Placing dishes in baskets: Incorrectly placed items can mean
that the washing water does not reach the items during washing
and rinsing.
• Soaking: Items with hard dried food. Soak the dishes in water. Do
NOT use washing-up liquid.
