Cleaning the interior
To achieve an optimal wash result and to increase the service life of the warewasher, we recommend cleaning the interior
daily.
Note
Risk of rust due to foreign bodies
Damaged wire grate baskets, wash items that are not rust-free, incorrect cleaning utensils and water pipes
not protected from rust can cause corroding foreign bodies to enter the interior of the warewasher. These
foreign bodies can also cause the material “stainless steel” to corrode.
Ø
Use only undamaged wire grate baskets, suitable wash items and suitable cleaning utensils.
The following materials must
not
be used for cleaning:
– High-pressure cleaner, steam jet
– Detergents containing chlorine or acid
– Cleaning sponges or wire brushes containing metal
– Abrasives or abrasive cleaning agents
Ø
Hose down the interior with a water hose.
Ø
Remove dirt with a brush or a cloth.
8.7
Cleaning the outside of the warewasher
The following materials must
not
be used for cleaning:
– High-pressure cleaner, steam jet
– Detergents containing chlorine or acid
– Cleaning sponges or wire brushes containing metal
– Abrasives or abrasive cleaning agents
Ø
Clean the display with a damp cloth.
Ø
Clean the external surfaces using a stainless steel cleaner and stainless steel polish.
8.8
Descale the warewasher
If the warewasher is operated with hard water and without water treatment, then the boiler, the interior of the machine, all
the water lines and components may develop scale. Grease residues and dirt that remain in the machine can contribute
towards hygiene risks, while scaling can lead to failure of heating elements. Regular removal of this scaling is therefore
necessary / essential.
The descaling programme can be used to descale the interior of the machine (
).
The water lines and the boiler can be descaled only by an authorised service technician.

Maintenance by the customer service department
We recommend that you have an authorised service technician carry out maintenance of the warewasher at least once a
year so that vulnerable components subject to ageing and wear can be checked and replaced accordingly. Original spare
parts must be used for repairs or to replace consumable parts.
Consumable parts are, e.g.:
– Dosing tubes
– Supply hose
– Curtains
Service interval
The warewasher control unit specifies the number of operating hours or wash cycles at which the pic-
togram for service is shown.
Note: This function is deactivated ex-factory. On request, the service technician can activate this
function.
