English 8 Cleaning and maintenance
8.6 Descaling 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. Limescale deposits and dirt that remain in the machine can contribute towards hygiene risks,
while scaling can lead to failure of heating elements. In case of limescale deposits, the warewasher must be descaled.
The interior of the warewasher can be descaled using the descaling programme (} page 53). We recommend running the descaling
programme at the end of the working day only, as the machine's tank is emptied when the programme starts and ends.
The water lines and the boiler can only be descaled by an authorised service technician.
8.7 Changing the activated carbon filter
Note: Only for AE RO warewashers with integrated reverse osmosis module.
Ø
Reset the activated carbon filter counter (} page 55).
8.8 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 re-
pairs or to replace consumable parts.
Consumable parts include:
– Dosing tubes
– Inlet water hose
– Door seal
– AE RO (optional): the reverse osmosis module membranes
– AE RO (optional): activated carbon filter
Service interval
The warewasher control unit specifies the number of operating hours or wash cycles at which the pictogram for
service is shown.
Note: This function is deactivated ex-works. On request, the service technician can activate this function.
