Chlorine And Component Damage - Miele PW 6241 Operating And Installation Instructions

Warning and Safety instructions
12

The application-technical recommendation of chemical washing
additives does not mean that the appliance manufacturer is
responsible for the effects of these addtives on the wash load and the
washing machine. Note that product changes not disclosed by the
manufacturer of these aids may affect the quality of the washing
result.

Only use dyes, dye removers, and descaling agents suitable for
use in a washing machine. The manufacturer's instructions on the
packaging must be observed.

Dye removers contain sulphur compounds which can cause
damage such as corrosion. Dye removers must not be used in the
washing machine.

Check the washing result for laundry soiled with biological oils or
greases. Inadequately washed laundry can cause spontaneous
combustion during the drying process. Use special detergents or
wash programmes for such laundry.

Do not use a pressure washer or hose to clean the washing
machine.

Chlorine and component damage


Frequent use of chlorine products increases the risk of damage to
components.

The use of substances containing chlorine, such as sodium
hypochlorite and chlorine bleach in powder form, can however result
in damage to the protective layer of stainless steel and corrosion on
components. Therefore, refrain from using agents containing chlorine.
Use oxygen-based bleaching agents instead.
If, however, chlorine bleaching agents are used, an anti-chlorine
treatment must always be carried out. Otherwise, the washing
machine components and the load may suffer lasting and irreparable
damage.

Anti-chlorine treatment must be carried out immediately after
chlorine bleach has been used. Hydrogen peroxide and oxygen-
based detergents and bleaching agents are suitable for anti-chlorine
treatment. The suds must not be drained in between.
Treatments with thiosulphates can result in gypsum-like deposits,
particularly in combination with hard water. This gypsum can build up
in the washing machine or cause incrustations on the laundry.
Treatment with hydrogen peroxide is recommended over treatment
with thiosulphates because hydrogen peroxide neutralises chlorine.
The exact dispensing quantities and the treatment temperatures
required must be set and tested on site in accordance with the
dispensing recommendations of the detergent and additive
manufacturers. The laundry must also be tested to check whether it
contains any active chlorine residues.
