10.6 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.
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.

Machine with built-in water softening device EW10

(Not in case of machines with air gap)

11.1 General

If the red lamp lights up, the capacity of the water softener has been almost ex-
hausted. About a further 10 program cycles are possible before the water softener is
completely exhausted. It is therefore possible to delay the necessary regeneration
until a time when the machine is not in use.
It is important to note that if the machine continues to be used when the water sof-
tener is exhausted, capacity can be reduced and the machine may even become
unusable.

11.2 Adjustment of water hardness

The water softening device is pre-set to 30°Gh in the factory. When the service engineer
installs or commissions the appliance he should adjust this value depending on the actual
water hardness. Should there be any further changes in the water hardness, this parame-
ter must be adjusted accordingly as set out in the Short Programming Instructions.
