The dishware should be checked after each wash for:
PROBLEMS
Starch spots
Misting
Protein residues
Detergent residues
WD-ACS 47D
CAUSES & MEASURES
•
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. A service
technician should be contacted to rinse the equipment with water
when replacing the detergent and drying agent. The dosing affects
both detergent and drying results of the dishware. The hardness
level of the water affects the consumption of detergent. Contact the
detergent supplier.
•
Temperatures: At incorrect temperatures the dishes will not be
clean. Contact a service technician if you need to change the set
values.
•
Washing time/contact time: If cleaning is inadequate, the contact
time can be increased.
•
Time/water volume: If starch spots or misting can be seen, or if
there is still detergent residue on the item, this may mean that the
flow through the wash arms during the final rinse is too low. The fi-
nal rinse flow can be checked and adjusted by a service technician.
The duration of the final rinse may also play a part. Increase the
contact time if necessary.
•
Cleaning the machine: Insufficient cleaning of the machine af-
fects the results of the washing. Ensure better cleaning of the ma-
chine.
•
Soaking: Items with hard dried food. Soak the dishes in water. Do
NOT use washing-up liquid.
•
Changing the water: How often the water needs to be changed
depends on several factors, such as the number of items being
washed, how well food residue is scraped off the item, how much
detergent there is in the washing water etc. It is therefore important
to continuously check the wash result, which may indicate when it
is time to change the water.
•
Water circulation: If water circulation in the machine is not good
enough, this can lead to problems such as starch spots. Contact
the service company for help in dealing with the problem.
•
Water hardness: If the water used for washing is hard (>10° dH),
a higher concentration of detergent may be needed to ensure the
washed items emerge clean. Contact your detergent supplier!
