What people are saying

Rated 1 out of 5 by from No Service Places Available! We bought this dishwasher two years ago. Yesterday there was an error code AE and water on the floor. I followed the website, but I couldn't get the code to go. I called LG who gave me a number of a repair place - which is not taking service calls. I've called two other places - the same thing. No where else in town will fix LG dishwashers. Please make sure there is a repair place in your community that will work on LG. Otherwise, I've got to replace a two year old dishwasher instead of fixing it.

Rated 3 out of 5 by from Great design but stopped drying after 3 years Love the look and flexibility of the washer but after only 3 years, our machine stopped drying the dishes. Also, I would have liked to have the option of a quicker express cycle. For dishes that are almost clean going in, it is annoying to have to wait over 2 hours for the “fastest” drying cycle available.

Rated 1 out of 5 by from Control panel issue I've had the this dishwasher for a year and half. Cracks have appeared at the control panel and now the buttons are completely non functional even though the tub light still powers on. Apparently, this is a common problem when researching this on the internet. Apparently I need a new control board and assembly due to the cracks. I've already removed the control panel (it took me two minutes). Trying to convince LG support to send me a new part under warranty is a non starter, they want to send out a technician (which will cost more than the parts) who will probably tell me I need a new part. Look, I get it, LG probably doesn't want people self diagnosing and getting free parts on our own claims. However, now I'm just going to grudgingly fix this myself, paying out of my pocket elsewhere for parts, and vowing not to buy anything else from LG again...

When I try to start the cycle it shuts off

Asked by: Yui567
Hello Yui567. As per the instructions in your owner's manual for the LG Top Control Smart wi-fi Enabled Dishwasher with QuadWash™, Model # LDT779BM, when you use method 1 and press the Start button, the door must be closed within four seconds. If the door is not closed within four seconds, the white LED with time flashes, an audible tone is heard, and the cycle does not start. If you use Method 2., close the door first and then press the Start button to operate the dishwasher. If that is not the issue, please contact us via the AI-supported Chatbot, https://www.lgechat.com/us/index.html. Our Customer Interactive Center is again taking inbound calls and providing call-back support after a brief period of online-only service scheduling. As we work to respond to your inquiry as soon as possible, we appreciate your patience while we take care of our customers during this challenging time. The Chatbot will be the quickest option at this time but you can also contact us via email: https://www.lg.com/us/support/email-appointment...^IFV
