Correct use
This dishwasher is designed for operation with water and cleaning agents suitable for
use in dishwashers only. Organic solvents and flammable liquid agents must not be used.
This could cause an explosion, damage rubber or plastic components in the dishwasher,
and cause liquids to leak out of it.
Only use cleaning agents formulated for use in dishwashers. Unsuitable cleaning agents
could adversely affect components of the dishwasher or the wash items.
Do not sit, stand, or lean on the opened door or dish rack. This could tip or damage the
dishwasher.
After any plumbing work, the water pipework to the dishwasher will need to be vented. If
this is not done, components can be damaged.
Please be aware that the dishwasher may be operating at high temperatures. When the
door is opened there is a risk of burning or scalding. Wash items, baskets, and inserts
must be allowed to cool down before they are unloaded. Any water remaining in containers
could still be very hot. Empty them into the wash cabinet before taking them out.
The water in the wash cabinet is NOT safe to drink!
The pretreatment of items (for example with dishwashing liquid and other detergents),
but also some types of soiling and some detergents, can cause a build-up of foam in the
wash cabinet. Foam can have an adverse effect on the cleaning result.
Foam escaping from the wash chamber can cause damage to the dishwasher. If foam
escapes, the program must be canceled immediately and the dishwasher must be discon-
nected from the mains electrical supply.
Depending on the properties of the flooring and footwear worn on it, liquids can cause a
slipping hazard. Keep the floor dry where possible and take care to clean up any liquid
spills straight away. Take the necessary precautions when cleaning up hazardous sub-
stances and hot liquids.
When using cleaning agents and specialized products, it is essential that the manufac-
turer's instructions are followed. Cleaning agents must only be used for the purpose they
are designed for by the manufacturer to avoid any material damage or the occurrence of
strong chemical reactions (e.g., oxyhydrogen explosion).
Under certain conditions, hydrogen gas might be produced in a hot-water system that
has not been used for two weeks or more. HYDROGEN GAS IS EXPLOSIVE. If the hot-wa-
ter system has not been used for such a period, before using the dishwasher turn on all
hot-water faucets and let the water flow from each for several minutes. This will release
any accumulated hydrogen gas. As the gas is flammable, do not smoke or use an open
flame during this time.
To avoid material damage and corrosion, do not allow any acids or solutions containing
chloride to get into the wash cabinet or onto the casing. Similarly avoid any ferrous materi-
als with a corrosive effect.
Do not wash items soiled with ash, sand, wax, lubricating grease, or paint in the dish-
washer. These materials will cause damage to the dishwasher.
Do not clean the dishwasher or its near vicinity with a hose or a pressure washer.
