9.6 De-scaling
If the appliance was operated with hard water, the boiler and wash tank could have lime
scale deposits. De-scaling of the tank interior, boiler housing, tank heating, boiler heating
and wash and final rinse system then becomes necessary
IMPORTANT!
For de-scaling the appliance use only products suitable for industrial dishwashers.
Please observe the instructions of the manufacturers of such products.
After de-scaling the appliance:
•
Remove the de-scaling agent completely from the appliance. 1 or 2 rinse cycles with
fresh water are necessary to achieve this.
Even small residues of de-scaling agents can be sufficient to destroy plastic parts and
sealing materials! If the appliance is heavily scaled, you should ask a service engineer
from the agency responsible to de-scale the boiler.

10.1 General description of the washing machine
10.1.1 Execution
Square basket appliance with stationary basket
10.1.2 Wash principle
The appliance has one wash and one final rinse cycle.
The temperature regulator maintains the wash temperature of 58-60 °C. Centrifugal
pumps moves the water from the wash tank into the wash nozzles. The water jets reach
the items to be washed out of differing directions. Therefore an even washing result can
be guaranteed.
The washing cycle is followed by the fresh water final rinse. The items are rinsed via a
separate nozzle system with hot fresh water at 80 - 83° C. Thus heating up the items for
the following drying process. At the same time the final rinse water serves for the regen-
eration of the wash water, the level of soil of the wash water thus being reduced.
