What people are saying

Rated 2 out of 5 by from Very disappointed in the life of dishwasher Worked up until about a month ago and now won’t power on. Problem may be the control board and it’s an expensive part to replace. I’m disappointed in the life of this product. I have other LG appliances and so does other family members so didn’t even hesitate about buying this. I have read more reviews about this and most say theirs has ran for about the same amount if time and quit. Replaced the control panel only to have it go out again. I feel that this is probably an on going problem or maybe even a defect in the way it is made. It also could be the top function button design because the front function design, which is the type other family has, and they have had no problems and their product is even older than mine was. I have replaced it with a different product. Just didn’t trust buying another LG.

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.
