Operating instructions
4.2 Washing
DIN 10510 is a German standard which describes how the washing process must
work in a tunnel dishwasher in order to ensure good washing results. Amongst
other things, it recommends that the contact time should be around 120 seconds
for normally soiled loads. The contact time is the time which the load spends in a
wash or rinse zone with washing water containing detergent. In principle this
means the period from when the load enters the pre-wash zone to when it is
rinsed with clean water in the final rinse zone. The standard is a useful means of
comparing the capacity and consumption of different dishwashers.
Proceed as follows:

When washing is to start, the dishwasher must be prepared, i.e. the wash-
ing tanks must be filled and the water in them heated.
Scrape off food residues. Items with dried-on food residue may need to
soak.
Put the dishware in baskets. Plates and trays must be placed longitudinally
in the machine.
Select the contact time / washing time on the touch panel in the activity
field.
Check the wash result when the item is removed from the baskets.
In the event of a fault on the dishwasher during operation (machine fault or
human error), an alarm will be shown in the display on the dishwasher's
touch panel. Certain machines can be equipped with lights to indicate
whether any alarms are active in the dishwasher.
Before washing starts, you should make sure that you know where the
dishwasher's emergency stop is located.
