What people are saying

Rated 1 out of 5 by from Terrible performance, worse service DO NOT BUY. We bought this 2 months ago. It does NOT clean dishes. I have to rewash many of them them by hand — a terrible waste of energy and scarce water. I have contacted LG numerous times. Every time, LG asks for “more information”, rather than sending a tech to repair the problem or replace the unit. LG makes poor quality units and refuses to stand behind its products.

Rated 2 out of 5 by from LG Dishwasher Display I ordered my new appliances from Home Depot and it took months to get them and no pandemic then. I haven't been able to use my dishwasher as it is broken. The dishwasher always has been one to have to be coaxed to work. Always had to restart over and over, as it would stop mid cycle. I have been having repairs, first they replaced the interface part with all the buttons and settings, then the door switch and the control board. Now it doesn't work at all. It has been weeks and weeks with the extended warranty company, Asurion, to get all this done. Took 3 days last week just to get another appointment lined up. They seem to drop the ball and want the customer to make lots of calls to get something done. The stove and refrigerator were somewhat easier to get fixed, but I'm really tired of using so much time and effort to get things resolved.

Rated 1 out of 5 by from Non stop issues I am not one to write reviews, but we purchased this product in a suite package through Home Depot in 2018 based on the recommendation from the sales person at HD that LG was top of the line. The dishwasher would periodically not start and I would have to go switch the breaker and then it would run again. Now it makes a terrible and extremely loud noise when it runs. So loud that you can hear it all the way in the 2nd floor bedroom. Even though the product has been discontinued, gee I wonder why! I would not recommend any LG products due to the poor customer service. They could not do anything because it was out of it's warranty timeframe. I expected more from LG, especially to stand by there products that with all due respect as others have mentioned are defected and not worth the price tag $700 they have. Will NEVER buy another LG product again based of my experience!

Asked by: ellbartto
The actual running time and cycle time displayed may change depending on options chosen, soil level, water temperature, and hardness of water. Therefore, display time and actual running time can be different. ^CP
