Height adjustment
You can adjust the height of the upper rack so that the lower rack can accommodate larger sized dishes. Depending on the height of the upper rack, the lower rack can accommodate plates up to 12 inches (30 cm) in diameter, and the upper rack can accommodate plates up to 8 inches (20 cm) in diameter.

To raise the upper rack
Pull the upper rack upwards. The adjustable handle will latch, and the upper rack will raise.
To lower the upper rack
Hold both the adjustable handles located at the left and right sides of the upper rack, and then evenly press down.
CAUTION
To remove the upper rack

To remove the upper rack, pull the upper rack to the front until it is fully extended, and then lift it slightly to remove. See the figures above for the illustrated steps.
CAUTION
Unsuitable items for the dishwasher
Wash only items such as glass, porcelain, and cutlery which the manufacturer declares as dishwasher safe. Do not wash aluminium (e.g. grease filters). The dishwasher may damage aluminium, or in extreme cases, cause a severe chemical reaction.
Do not wash the following items in the dishwasher.
Into the lower rack
10 place setting

12 place setting

Load cookware (pots, pans, etc.) up to 12 inches (30 cm) in diameter into the lower rack. The lower rack is specially designed for dinner dishes, soup bowls, plates, pots, lids, and casserole dishes. Load plates into the centre column of the rack so that the top of a plate faces the bottom of the next plate. Load large items such as pans and pots into the dishwasher so their inner cavities face downwards. We recommend loading cups, stemware, and small plates into the upper rack. See the recommended loading cases below.
Detergent guidelines
All dishwasher cycles require detergent in the detergent compartment. Apply detergent as appropriate for the selected cycle to ensure best performance.
WARNING
Dishwasher detergent contains irritants and caustic chemicals that can induce respiratory conditions. If you have consumed dishwasher detergent or inhaled detergent fumes, seek medical attention immediately.
CAUTION Use dishwasher detergent only. Other types of detergent produce excessive foam, which may decrease the dishwasher’s performance or cause it to malfunction.




Rinse aid improves the drying performance of the dishwasher. When the Rinse Refill indicator lights up on the control panel, refill with rinse aid. Only use liquid rinse aid.
Powdered rinse aid will clog the compartment opening and cause the dishwasher to malfunction.
CAUTION



Water reflector
The water reflector automatically detects obstacles inside the dishwasher that can interfere with the reflector’s signal. If an obstacle is detected at the end of a cycle, "0" blinks for several minutes. The dishwasher chimes for several minutes. If this happens, remove the obstacle.

Cleaning
Keep the dishwasher clean to improve performance, reduce unnecessary repairs, and lengthen the lifecycle.
Exterior
Clean spills on the surface of the dishwasher as they occur. Use a soft, damp cloth on the control panel to gently wipe away spills and dust.
CAUTION
Interior
Clean the interior of the dishwasher on a regular basis to remove any dirt or food particles. Wipe inside the dishwasher and inside the door with a wet dishcloth. We recommend filling the detergent dispenser with dishwasher soap, and then running the Self Clean cycle with an empty dishwasher.
To keep the cutlery pad clean, turn it over after using it. To remove white spots and odours from the cutlery pad, run the Self Clean cycle with an empty dishwasher and no detergent until the cutlery pad flushes. Then, stop the cycle and apply an 8-ounce cup of white vinegar into the lower basket. Close the door and resume the cycle.
CAUTION Do not remove the front seal (the long rubber seal enclosing the opening of the dishwasher). The seal keeps the inner side of the dishwasher sealed.

Use a damp cloth to remove lime scale or grease deposits inside the dishwasher. Alternatively, apply some detergent, and then run an empty cycle using the highest rinse temperature.
CAUTION To avoid damaging the motor, use caution when manually moving the water reflector.
Nozzles
To prevent the nozzles from being clogged or if the nozzles are clogged, remove and clean each nozzle. Use caution when removing the nozzles as they may break.
Upper nozzle

Top nozzle

Filter
We recommend cleaning the filter every month.

1. Open the door, and then remove the lower rack first.
2. Turn the filter handle counter clockwise to unlock the filter cover.

3. Remove the filter cover, and then the cylindrical micro filter underneath.

4. Remove any dirt and impurities from the micro filter and the filter cover.
5. Rinse them with running water, and then dry well.

6. Reinsert the filter, and then the filter cover.
7. Turn the filter handle clockwise to lock.
CAUTION Make sure the filter cover is closed properly. A loose cover can reduce the filtering performance.
Drain pump

If the dishwasher fails to drain because the drain pump is clogged with foreign matter or there is an abnormal noise coming from the drain pump, you must unclog and clean the drain pump as instructed below.
1. Remove the lower rack.
2. See the Filter section to remove the cylindrical micro filter. Then, remove any moisture from the filter using a sponge.

3. Remove the drain-pump cover by pushing its handle in the arrow direction (1), and then pulling up (2).
4. Check the impeller if it's in good condition. Then, remove any impurities from the pump.
5. Reinsert the drain-pump cover into place, and then press it down until you hear a clicking sound.
Long-term care
If you will not use the dishwasher for an extended period of time, first drain the unit completely, and then disconnect the water hose. Shut off the water supply valve and the circuit breaker. Water remaining in the hoses or the internal components can damage the dishwasher.
