WHAT YOU CAN WASH
Many items come with instructions indicating
whether they are dishwasher-proof. However, the
following comments may be useful:
CHINA: In some cases the decoration may be
unprotected, on the outside of the glaze, and
colours may fade if they are washed repeatedly by
machine. Be aware of this when buying new china.
GLASS: Problems rarely occur. You should make
sure there is rinse-aid in the machine and that the
correct amount is dispensed (see below). CRYSTAL
should not be washed at temperatures exceeding
55°C.
STAINLESS STEEL: Very tolerant, but direct
contact with detergent can cause it to spot. If you
use detergent for the pre-wash, you should therefore
not place the cutlery basket directly in front of the
detergent dispenser. (Pre-wash detergent is placed in
the recess on the flap of the detergent dispenser.)
ALUMINIUM: Coloured or anodised aluminium is
bleached by dishwasher detergent. The shiny surface
loses its gloss and becomes slightly blotchy.
SILVER: You can wash silver items in the machine
but take care to ensure that the silver does not come
into contact with other metals. Do not mix silver
and stainless steel.
PLASTICS: Plastic parts should not be positioned
directly above the heating coils (on the left at the
very bottom of the machine). Avoid using the
heated drying function. Items or parts made of
certain types of plastic may distort.
WOOD: Items which consist wholly or partly of
wood (e.g. handles) should not. be washed in a
dishwasher as they may crack or dry out.
OTHER ITEMS: Cutlery with glued or cemented
handles may be affected by hot 'water so that the
handle works loose. Bakelite pan 'handles may crack
or work loose. Some laminated materials are also
sensitive to high temperatures. i
N.B. Do not wash sandy objects such as flower-pots. The
sand can cause problems in the machine.
