Servicing and maintenance

8.3 Monthly cleaning

Cleaning the dirt trap
 Close the on-site stop cock for the water supply.
 Clean the dirt filter in the dirt trap.
Only for the PG 8172 ECO model

8.4 Descaling

If the machine is operated with water of high hardness without water treatment, descaling is necessary at
regular intervals ( 12).

8.5 Maintenance by the Service Department

We recommend that you have an authorised service technician carry out the maintenance of the machine at
least twice 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 spray arms
 Hood seal
 Water supply hose
In the electronic control unit, the number of hours of operation or wash programmes before
servicing should be performed can be programmed and at what number of hours of operation
remaining the symbol for maintenance/service is displayed. If necessary, have this function
activated by an authorised service technician.
