8.2.3 Cleaning the dirt trap
 Clean the debris filter in the dirt trap
8.2.4 Descaling
If the machine is operated with very hard water and without corresponding 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.
Caution
If the machine is equipped with a heat pump, it is essential for the machine to be connected to
softened water so as to prevent any limescale buildup in the heat exchanger.
 Drain the machine ( 8.1.2).
 Interrupt the detergents dosing (e.g. pull out the suction tube or switch off the dosing equipment) in order
to prevent chlorine gas from being formed if the detergent containing active chlorine comes into contact
with descaler.
 Fill the machine ( 7.1.2).
Warning
When using chemicals, comply with the safety notes and dosage recommendations printed on
the packaging.
Wear protective clothing, protective gloves and protective goggles when handling chemicals.
 Add the descaler to each of the tanks of the machine in accordance with the recommended dosage.
 MTR series machines: Run the machine with empty washing racks until all the limescale deposits have
been removed.
 MTF series machines: Put plates onto the conveyor belt and run the machine 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 ( 8.1.2).
Caution
The descaler is not allowed to remain in the machine for several hours.
 Fill the machine ( 7.1.2).
 MTR series machines: Run the machine with empty washing racks in order to remove descaler residue
from the washing system.
