What People Are Saying

Rated 1 out of 5 by from Leaks & Stops Mid-Cycle We bought this dishwasher a few months ago based on our positive experience with our LG Washer and Dryer. Visually it looks great on the outside, however we had nothing but problems with its performance. After installation we noticed that frequently the dishes would come out dirty and there would be water in the bottom of the dishwasher. It appeared that the door would not latch properly and this would stop the dishwasher mid cycle and cause errors in the touch panel (e.g. would not work for several hours after). Frequently there would be water leaking on the floor when it was in operation, seemingly pointing to a problem with the door latch. This water leaking appeared to affect the trim on the cabinets around the dishwasher (wood swelled from repeated exposure to moisture). After multiple technician visits, LG issued a manufacturers refund.

Rated 5 out of 5 by from Absolutely love this dishwasher You will not be disappointed...all the digital features and oh so quiet. I bought this a week after I purchased the LG convection oven (wLRE3193s) also with all the digital features and I really like the the convection feature; ended up with a perfect Thanksgiving dinner. These are upscale products. Ladies or men, whoever spends the most time in the kitchen, you will love these appliances. I would buy a side by side refrigerator (65 inches high) but no one makes them accept one brand that I refuse to buy.

Rated 5 out of 5 by from So far so good! Have only had it one month, but has worked flawlessly thus far. The easily adjustable rack allowed me to fit dishes in efficiently with no lost space. The top cutlery rack is great, all dishwashers should have that. The unit is very quiet, that was one of our top priorities in buying a new dishwasher. We haven't used many of the advanced features, but one thing I did do was get it connected via wifi. I can check my phone to discover that it is currently in the Washing cycle, with 1h57mins to go. I am not sure how useful that feature is, but my kids love it. Apparently you can also download custom wash modes if you want, but I haven't tried to do that. The unit looks very modern, the control panel has touch-sensitive lights which disappear when off. What else can I say? Works like a charm.

Rated 1 out of 5 by from DO NOT BUY!!! This dish washer leaked from the 2nd time I used it. It leaks from the bottom of the door and it leaks from the top of the door. It will also stop mid cycle and then open the door. It also does not dry the dishes. And yes I used rinse aid!! It is also very loud. And I have time to write this review because I have been on the phone for over 30 min waiting for customer service to give me a repair date. Which will be over a week from now if they can ever find my address as. I have to spell every letter and use it in a word. Yes still on hold with customer service.
