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.

Remove dirt with a brush or a cloth.
