8.7 Descaling the warewasher
If the warewasher is operated in a hard water area without a water treatment system, then the boiler, the machine interior
and all water-bearing lines and components may develop scale. Limescale deposits and the dirt and residual grease they
contain present a hygiene risk, while scaling can cause heating elements to fail. If limescale deposits form, the ware-
washer must be descaled.
The interior of the warewasher can be descaled using the descaling programme (} page 24). We recommend running the
descaling programme at the end of the working day only because the machine’s tank is emptied when the programme
starts and ends.
Water-bearing lines and the boiler can only be descaled by an authorised service technician.
8.8 Maintenance by the customer service department
We recommend that you have the warewasher serviced by an authorised service technician at least once a year so that
vulnerable components subject to ageing and wear can be checked and replaced as required. Original spare parts must
be used for repairs or to replace consumable parts.
Consumable parts include:
– Dosing tubes
– Supply hose
– Curtains
– Door seal
Warewashers with heat pumps (ClimatePlus option):
– Have the heat pump checked for leaks at least every 12 months by a certified refrigeration engineer (in line with the F-
Gas Regulation EU 2024/573).
– We recommend having the heat pump serviced annually by an authorised service technician (for descaling and clean-
ing).
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-works. On request, the service technician can activate this
function.
