11.3.1 Descaling
If the machine is operated with very hard water and without the appropriate water treatment, limescale can
build up in the boiler, in the interior of the machine and in all lines which carry water.
Limescale deposits and the dirt and grease residue they contain represent a hygiene risk, and the limescale
can cause the heating elements to fail. Therefore, it is essential to remove these deposits at regular
intervals.
You should have the job of correctly descaling the boiler and all pipes which carry water carried out by a
service technician authorised by Winterhalter.
You can descale the interior of the machine yourself using the descaling programme ( 16.6.1).
Warning
When using chemicals, adhere to the safety notes and recommended dosages printed on the
packaging.
Wear protective clothing, protective gloves and protective goggles when handling chemicals.
11.4 Maintenance by customer service
We recommend having the machine serviced at least twice a year by a service technician authorised by
Winterhalter. This service should also include having components which are subject to wear or ageing being
checked and replaced as necessary.
Examples of such components:
Water connection hose
Dosing tubes
Door seal
Winterhalter offers a service contract which includes this work and other services.
On the electronic control unit you can program the maintenance interval in operating hours and
set the number of remaining operating hours from which point the symbol for maintenance /
servicing is displayed. ( 18.1). If necessary, open the cleaning opening in the rotating wash field
with a coin and rinse the rotating wash field with water.
