10.4 Descaling
If the machine is operated with water of high hardness without water treatment, descaling is necessary at
regular intervals (
7.5.1).
10.5 Maintenance by the Customer Service Department
We recommend that you have an authorised service technician carry out the maintenance of the machine at
least once a year so that vulnerable parts 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, for example:
Dosing tubes
Door seal
Inlet water hose
Only for the Energy version:
The heat exchanger must be cleaned once a year. Depending on the degree of soiling, the performance of
the heat exchanger will reduce without maintenance.
Contact an authorised service technician for maintenance.
Service interval
The machine control unit specifies the number of operating hours or wash cycles at which the
pictogram for service is shown.
INFO
As a default, this function is deactivated. On request, the service technician can activate
this function.
