4.1.5 Descale
If the warewasher is operated with hard water and without water treatment, then the boiler, the interior of the machine, all
the water lines and other components may develop scale. Grease residues and dirt that remain in the machine can con-
tribute towards hygiene risks, while scaling can lead to failure of heating elements. Regular removal of these coatings is
recommended.
Using the descaling programme, you can descale the interior of the warewasher. The water lines and the boiler can be
descaled only by an authorised service technician.
For descaling, you need an acid-based descaler suitable for commercial warewashers. We recommend the Winterhalter
Descaler A70LS.
Ideally, start the descaling programme when the warewasher is empty and switched off. If the warewasher is already pre-
pared for use, it will automatically empty first.
Warning
Risk of chemical burn due to contact with descaler
Contact between descaler and the skin or eyes can lead to severe burns or serious eye damage.
Ø Wear protective clothing, protective gloves and protective goggles.
Ø Observe the danger and safety notes on the container and safety data sheet.
Warning
Danger of chlorine gas developing
Mixing active chlorine cleaner and acid-based descaler produces chlorine gas. Contact with chlorine gas
leads to eye, nose and throat irritations.
Ø Do not mix active chlorine cleaner and acid-based descaler.
Ø Ensure good ventilation when you descale the warewasher.
