8.5 Maintenance by the Customer Service
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 can be checked and replaced accordingly. Original spare parts
must be used for repairs and the replacement of worn parts.
Worn parts are, for example:

Dosing tubes

Bearings of the rotating wash fields

Hood seal

Water supply hose
Only for the EnergyPlus und ClimatePlus models:
The heat exchanger must be cleaned once a year irrespective of whether there is a maintenance contract or
not. Depending on the degree of soiling, the performance of the heat exchanger will be reduced without
maintenance.

Contact an authorised service technician for the maintenance.
In the electronic control unit, the number of operation hours or washing programmes before ser-
vicing should be performed can be programmed and at what number of operation hours remain-
ing the symbol for maintenance/service is displayed. If necessary, have this function activated by
an authorised service technician.
