8.2.2 Descaling
If the machine is operated with very hard water and without suitable water treatment, limescale can build up
in the boilers, the interior of the machine and in all pipes that carry water.
Limescale deposits and the incorporated dirt and grease residues 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.
The job of correctly descaling the boilers and all pipes that carry water should be entrusted to a Winterhalter
service technician.
However, you can descale parts of the interior of the machine yourself by following the instructions below.

Drain the machine (

8.1.1).

Interrupt the dosing of detergents (e.g. pull out the suction tube or switch off the dosing equipment) in
order to prevent chlorine gas from being formed if the active chlorinated detergent comes into contact with
descaler.

Fill the machine (

7.1.2).
Warning
When using chemicals, comply with the safety notes and recommended dosages printed on the
packaging.
Wear protective clothing, protective gloves and protective goggles when handling chemicals.

Add the descaler to the tank of the machine in accordance with the recommended dosage.

Run the machine with empty washing racks until all the limescale deposits have been removed.

It may be necessary to dose additional descaler after an operating time of about 10 minutes.

Drain the machine (

8.1.1).
Caution
The descaler may not remain in the machine for several hours.

Fill the machine (

system.
