4. FEATURES & TECHNICAL EXPLANATION

4-1. Product Features

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.
