4.2.8 Checking the wash result
The dishware should be checked after each wash for:
PROBLEM
Starch spots
Misting
Protein residues
Detergent residues
WD-18CW
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
final 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
affects the results of the washing. Ensure better cleaning of the
machine.
•
Positioning items to be washed: 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 items 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
inadequate, this can lead to problems such as starch spots on
glass and on the undersides of plates. 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!
