INSTALLATION 17

2 Check the opening of door and repeat if
necessary until the door opens and closes properly.

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.

Case 2. The Door is Slanted to the Left
1 Unscrew (counter-clockwise) the rear right leg
and correct the level.

WARNING
· Do not load any items in upper rack when the lower rack is pulled out and loaded. Failure to do so may result in injury as the appliance could become unbalanced and topple over.
· Push the upper rack in all the way.
· Empty the lower rack first and then the upper one. It will avoid water dripping from the upper rack onto the dishes below.
· Do not open the door during operation or right after it has completed the wash cycle as the steam may cause scalding as the door is opened.

22 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.

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.

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.
