7.2.1 Cleaning the dirt trap
 Close the shut-off valve for the water supply
 Clean the dirt trap
7.2.2 Descaler
If the machine is operated with hard water without the relevant water preparation, the boiler, the machine
interior and all water lines can scale.
Grease residues and the dirt and grease remains in them are a great risk as regards hygiene and
scaling can lead to failure of heating elements. Regular removal of these layers is absolutely
essential.
In order to be able to descale all water lines and the boiler properly, assign this work to a Winterhalter
service engineer.
You can descale parts of the interior of the machine yourself with the help of the following notes.
 Drain the machine ( 7.1)
 Stop the detergent dosing (e.g. remove the suction pipe or switch off the detergent dosing device) in
order to prevent formation of chlorine if detergents containing active chlorine and descalers get mixed.
 Fill the machine ( 6.1)
 Wait till the machine is ready for operation
When handling chemicals, observe the safety notes and dosing recommendations printed on
the packing.
Wear protective clothing, protective gloves and protective goggles when handling chemicals.
Warning
 Supply the recommended dose of the descaler in the machine tank
 Trigger the intensive mode once or twice
 Drain the machine ( 7.1)
The descaler may not remain in the machine for hours.
Caution
 Fill the machine ( 6.1)
 Trigger the intensive mode once or twice to remove the remaining descaler from the washing system
 Drain the machine again ( 7.1)
 Restart the detergent dosing
