If you raise the Upper Rack, you can load large dishes in the Lower Rack.
(Max. 14 in.)
The tall tub provides large dishes loading as well as large capacity.
LG dishwashers let you load oversized items in the Lower and Upper Rack.
Newly introduced Slim Direct Inverter motor is inverter-controlled. Speed is
controlled based on program selection. It also offers high energy efficiency to
minimize energy loss.
This is one of the best performance solutions for drying dishes because it
minimizes venting humid air to the outside of the dishwasher. In addition, this
system ensures better drying results compared to the condensing drying
system.
Because of alternating water spray between the Upper and Lower
Rack, the water pressure allows superior performance and reduced
consumption of water and electricity.
For best wash results, the self-cleaning filter system continuously cleans the
water as it circulates. Your LG dishwasher has a self-cleaning filter that grinds
food into small particles before it goes down the drain.

USING YOUR DISHWASHER
Before using the dishwasher, please
read Important Safety Instructions.
Water supply temperature should be 120 (49 )
for better washing and reasonable cycle time.
For this reason, use hot water faucet only.
It is also important that the dishwasher is loaded
according to instructions for the effective cleaning.
When loading your dishwasher, make sure that
insoluble items such as bones, toothpicks and
pieces of paper have been removed.
When loading the dishwasher, observe the
following general guidelines;
1. Deep based items should be placed at an
angle to help water run off and dry properly.
2. Remove solid, burnt-on scraps from dishes
prior to loading in the dishwasher.
3.Load only items which are dishwasher safe.
NOTE Please avoid utensils that are non-heat
resistant, metal decorated, etc.
Loading the Lower Rack
This lower rack allows max. 14 in. plates, pans or
any utensils which mean the size of rack is bigger
and is higher than industry standard thanks to
super big tub capacity.
NOTE Do not obstruct the rotation of the spray
arms. Make sure large items do not prevent
the detergent dispenser from opening.
The lower rack is best loaded with dinner plates,
soup bowls, dishes, pots, pans, lids and even a
grill tray. Plates should be positioned upright and
facing the center of the rack. Pots, pans and
large dishes must be turned upside down.
Basically the lower rack is not meant to load
small items like cups, wine glasses or small
plates. These items should be loaded on the
upper rack for proper distribution.

up in order to reduce the risk of cut-type injuries.
