What people are saying

Rated 3 out of 5 by from Full disclosure I bought this set through Costco. Delivered and installed by their technicians. A week later, leaking water from some unobservable location. Now waiting for a follow up service call. Thankfully, Costco offers no question returns or exchanges so, apart from the frustration, no harm done. As far as the ease of use, it’s pretty smart, maybe too smart. There may be features I’ll never discover. One irritation is the lack of illumination on the control panel. It’s very hard to read the control options. Seems like a silly oversight. Bottom line is, I’ll keep it, assuming the leak is resolved.

Hi, does this washer have the ability to be filled with detergent - load and go/ezdispense?

Asked by: Sam Reddy
The Load & Go™ Dispenser is not an LG feature. That is a feature used by another manufacturer. That feature is called ezDispense™ on LG washers that support the feature.
