Wash items not suitable for
dishwashers:
- Wooden cutlery and dishware or
items with wooden parts. These may
discolour and fade. The glue used in
these items is not dishwasher-proof
and wooden handles may come
loose after being washed in a
dishwasher.
- Craft items, antiques, valuable vases,
and decorative glassware. Such
items are not suitable for
dishwashers.
- Plastic items that are not heat
resistant. The high temperatures in
the dishwasher may cause them to
melt or lose shape.
- Copper, brass, tin, and aluminum
items. These may discolour or
become dull.
- Colours painted over a glaze. These
may fade after a number of washes.
- Delicate glassware and glassware
containing lead crystal. Clouding may
occur over time.
Silverware
Silverware that has been in contact with
foods containing sulphur can discolour.
These include egg yolk, onions,
mayonnaise, mustard, fish, and
marinades.
Silverware
previously cleaned with a
silver polish
may still be damp or
spotted at the end of a program, where
water has not run off smoothly.
Useful tip:
Rub the silverware dry with
a cloth.
Damage due to caustic alkaline
detergents.
Aluminum parts (e.g., the grease
filters of ventilation hoods) can be
damaged by caustic alkaline
detergents. In extreme cases, there
is a risk of an explosive chemical
reaction (such as an explosive
oxyhydrogen gas reaction).
Aluminum components must not be
cleaned in the dishwasher with
caustic alkaline commercial or
industrial detergents.
Useful tip:
When purchasing new
dishware and cutlery, make sure they
are dishwasher safe if you want to wash
them in the dishwasher.
Glass care
- Clouding may occur on glasses after
frequent washing. When washing
delicate glassware in the dishwasher,
ensure that only a special glass-care
program with very low temperatures
is selected (see “Program overview”).
This will reduce the risk of clouding.
- Purchase glassware that is
dishwasher-safe (e.g., Riedel
glassware).
- Use detergents with glass protective
additives.
