Disinfection
Thermal disinfection and chemo-thermal disinfection are programmes for disinfecting
textiles.
Thermal or chemo-thermal disinfection is carried out. Suitable detergents are to be used
for the chemo-thermal disinfection.
All programmes are locked. This means that after 1 minute into a programme, they can
only be cancelled, stopped or have parts skipped by entering the "Expert code" (see oper-
ator level).
To avoid recontamination, the water inlet for the rinse cycles in the disinfection pro-
grammes is not supplied via the detergent drawer.
To disinfect contaminated mains water, a disinfection rinse can be activated instead of
the last rinse cycle. In this rinse, the rinse water is heated to 65 °C to deactivate water-
borne bacteria. The programme running time is extended and the door can only be opened
once the temperature in the machine has fallen below 50 °C.
If "Pre-wash" is selected, place the detergent directly in the drum. If necessary, the 
and  compartments can be used to add detergent in the main wash cycle.
