SenseClean system

It's a big washer, but that doesn't mean you have to do a big load every time. LG's SenseClean system automatically sets the water level and wash time for each load based on the weight.

Dryer cords are not shipped with the dryer. It is the responsibility of the consumer to purchase the appropriate cord for their home.
