3. FEATURES & TECHNICAL EXPLANATION

3-1. Product Features

LARGE CAPACITY

HYBRID DRYING SYSTEM

LG dishwashers allow you to load very large items in both the upper and lower racks. The tall tub provides extra overall capacity and the clearance to accommodate large dishes. Extra large items (max. 14 in.) may be loaded in the lower rack by raising the upper rack.

This system eectively dries dishes without the use of a heating element that would increase energy consumption.

STEAM WASHING (not available on all models)

Steam technology provides better cleaning performance than regular wash systems. Steam is the most energy efcient gentle care for your nest china and stemware.

VARIABLE SPRAY SYSTEM

Because the water spray alternates between the upper and lower racks, all of the power from the motor is directed to one rack at a time. This concentrates all the cleaning power of the motor on each rack in turn.

LIGHT TOUCH BUTTONS

The light touch buttons on the control panel make selections easy and convenient.

Cycles

Select your desired cycle.

Auto

This cycle senses the load size, soil amount and soil toughness. This cycle is optimized to achieve the best cleaning.

Heavy

This cycle is for heavily and hard soiled dishes. Heavy defaults to the highest spray intensity and uses the power of steam to wash heavily soiled dishes.

Delicate

This cycle adds the gentle power of steam to boost the cleaning power of the delicate cycle. The cycle is intended for effectively cleaning delicate items such as ne china and stemware.

Dual Control

This cycle washes the upper and lower racks at dierent spray intensities. The default setting for this cycle washes the lower rack with strong spray intensity and the upper rack with soft spray intensity. This provides optimum cleaning performance for mixed loads, including ne china and stemware. If other combinations are desired, use the steps listed below to change the intensities or to use the Half Load feature.

How To Use Dual Control:

1. Select Dual Control.

2. Press the Spray button to toggle between Soft, Medium and Strong for the upper spray arm.

3. After making your selection for the upper spray arm, press the Half Load button.

4. Press the Spray button to toggle between Soft, Medium and Strong for the lower spray arm.

5. Close the door to start the cycle.

Normal

This cycle is for normally soiled, everyday loads.

Quick & Dry
