Changing The Water - Wexiodisk WD-90 DUO Installation And User Manual

Using the dishwasher

4.3.3 Changing the water

the temperature of the water must not be too high (<40
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 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 cleaned, you should try selecting a program with a longer wash cy-
cle, see "Technical data" on page 57. 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
centration of detergent may be needed to ensure the washed items emerge
clean. Contact your detergent supplier.
Cleaning, rinse pipes – Cleaning of the machine is important for achieving a
good wash result. See "Care and maintenance" on page 37 for recommendations
as to how often cleaning should be performed. In certain cases it may be neces-
sary to clean more frequently than recommended.
Stacking of items – How the items are positioned in the basket is critical for how
the washing water will manage to rinse them during washing. This in turn will de-
termine the wash result, see "Positioning of items in baskets" on page 31.
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
washing, if they are to emerge fully clean. In such cases the items are soaked e.g.
overnight in water with a soaking agent. Follow the instructions of the detergent
supplier.
Ordinary washing-up liquid must NOT be used in the machine or for soaking. It
causes foam to form and produces poor wash results.
Take care to scrape off food residues from the items before putting them in the
dishwasher. If residues are properly scraped off, the water will not need changing
as often, saving time, money and the environment.
The water in the washer tank should be changed daily. More frequent changes of
water are needed if:
• Significant amounts of foam build up in the machine; e.g. if you can see
foam coming out of the waste pipe, or the strainer in the machine's tank is
covered with foam. If this occurs, the water should be changed
immediately.
• A lot of items are washed at certain periods of the day. Schedule water
changes so that a good wash result is achieved over the entire work shift.
Change the water, for instance, after periods when a lot of items have been
washed.
• On checking the wash result you discover any of the problems mentioned
in the chapter "Check the wash result" on page 38 above.
