Operating instructions
Scraping off – It is important that as much food residue as possible is scraped
off the items before putting them in the machine. Proper scraping off will mean the
water in the washer tank will not need changing as often.
Detergent and drying agent dosage – The dosage of the detergent and drying
agent will affect the wash result. If too high or too low a dosage is suspected, the
detergent supplier should be contacted. There is the option of fitting a sensor in
the tank to measure detergent concentration in the water. Using this, detergent
can be added automatically to achieve the right dosage. Contact your detergent
supplier!
Water change – The water in the tank should be changed at least once a day dur-
ing normal use of the dishwasher. In certain cases, e.g. if many or highly soiled
items are washed, it may be necessary to change it more often.
Water circulation – If water circulation in the machine is poor, 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.
Temperature – If the temperature during washing and the final rinse is too low,
the items in the wash will not emerge clean. If you suspect this is the case, contact
the service company.
If normal wash items are rinsed (pre-rinsed) before being put in the dishwasher,
the temperature of the water must not be too high (<40° C). There is then a risk
that proteins and starch will burn onto the items, and you will end up with a poor
wash result.
Program selection – The time taken by the wash cycle and final rinse, as well as
the volume of water used for the final rinse are all important for the wash result. If
the items are not clean, you should try selecting a program with a longer wash
cycle. The volume of water used for the final rinse of the washed items can be
adjusted by a service engineer. Contact the service company!
Water hardness – If the water used for washing is hard (>10° dH), a higher con-
centration of detergent may be needed to ensure the washed items emerge
clean. Contact your detergent supplier!
Cleaning, initial rinse pipes – Cleaning of the machine is important for achieving
a good wash result. See recommendations on how often cleaning should be per-
formed. In certain cases it may be necessary to clean more frequently than rec-
ommended.
Stacking of items – the positioning of items in the basket is crucial for how the
washing water will manage to rinse them during washing. This in turn will deter-
mine the wash result.
Soaking – (does not apply to potwash programs with granules, where soaking
should not be used) – In certain cases the items need to be soaked before wash-
ing, if they are to emerge fully clean. In such cases the items are soaked e.g. over-
night in water with a soaking agent. Follow the instructions of the detergent
supplier.
