4 Reasons to Buy LG Dishwasher


LDT7797BM-TurboExpressCycle_12-6-18-D1

Turbo and Express Cycles

Turbo Cycle will clean heavily soiled dishes in an hour using slightly more energy and water.*
Express Cycle will quickly clean lightly soiled dishes in 33 minutes.*

*This cycle does not have drying. Select the Extra Dry and Night Dry option or another cycle for better drying.

LDT7797BM-NightExtraDry_12-6-18-D1

More options for better drying

Extra Dry: This option adds extra drying time to the cycle and raises the heated rinse temperature.
Night Dry: Dishes left in the dishwasher overnight after the cycle ends can result in steam inside the tub condensing on dishes, leaving them wet. Night Dry runs the ventilation fan periodically to help vent steam from the tub.

LED Tub Light

The LED tub light activates when the door is open, offering a sophisticated interior look.
