installing the side cabinet securing screws.
Installing the Drain Hose
If the end of the drain hose does not fit to the drain
line, use a drain extension kit (optional) that is
resistant to heat and detergent.
• This should be available from a plumbing shop
or a hardware store.
Connection to the Waste Spigot
Check the waste spigot when initially installing. An
OE error can occur when the waste spigot below
the sink is not drilled out properly. To connect the
drain hose, drill out at least a 15 mm diameter hole
in the waste spigot before connecting and
securing.
CAUTION
• Make sure that plastic debris is not remaining
inside of spigot after it has been drilled out.
• Do not attempt to open the waste hole with a
screwdriver and hammer. This will induce debris
to become stuck and cause a malfunction.
• Caution should be taken when passing hoses
through Cabinetry holes as they may have sharp
edges and could damage the hoses. Smooth or
sand edges to avoid damaging the drain or inlet
hose.
• Make sure that the line is not kinked or sharply
bent.
• Make sure the drain hose is straight before
feeding the end of it through the hole for the
water supply.

OPERATION
NOTE
• Never use liquid dishwashing detergent in the
appliance.
• It is not recommended to rinse the dishes
manually before operating the dishwasher
because it increases water and energy
consumption.
• Washing tableware in a household dishwasher
usually consumes less energy and water in the
use phase than hand dishwashing when the
household dishwasher is used according to the
manufacturer’s instructions.
• Loading the household dishwasher up to the
capacity indicated by the manufacturer will
contribute to energy and water savings.
Before Using
This model has a water softener to soften hard
water.
NOTE
• The appliance can be used without dishwasher
salt if not required, however, the hardness level
needs to be set to H0 so that the icon does not
remain lit.
• In order to provide satisfactory rinsing results,
the appliance requires soft water, i.e., containing
little or no lime, otherwise water stains will be
left behind on the dishes and inside the
appliance.
• If the tap water exceeds a certain level of
hardness, it must be softened, i.e., decalcified.
This is achieved by adding dishwasher salt to the
water softener inside the appliance. The
required amount of the salt is set up according
to how hard tap water is.
Checking Water Hardness Level
Method 1
1 Check the water hardness in your area. The
water utility company can help you with this.
2 Set the softening system level of the appliance
according to the water hardness level.
Method 2
You can check water hardness by using the test
strip included in the product.
1 Immerse all reaction zones of the test strip for
about a second. Do not in running water.
2 Shake off excess liquid from the strip and wait
for 1 minute.
3 Check the water hardness colour from the
strip. Refer to the wrapper.
