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.

4.2.1 Feeding loads into the machine
Once the feed device begins to pull the basket into the machine, the basket must
not be pushed manually. This may disturb the wash cycle, resulting in impaired
wash results.
Leave the following gaps between the baskets when you feed them in:
•
•
•
•
•
Increase the distance if the items to be washed are heavily soiled.
WD-151E - WD-421E
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.
Choose between Automatic and Manual operation on the touch panel in
the activity field.
The most recently selected operating method will be saved for the next
time the machine is turned on.
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.
WD-151E = approx. 50 cm.
WD-211E = approx. 30 cm.
WD-241E = approx. 25 cm.
WD-331E = Hardly any gap (the baskets should be close together).
WD-421E = Hardly any gap (the baskets should be close together).
