What people are saying

Rated 5 out of 5 by from LG -Excellent Dishwaher I purchased this LG Dishwasher to complete my kitchen remodel to all stainless appliances and all LG Thinq appliances. I did quite a bit of research and having now had it 3 weeks I must say it has exceeded every expectation. It is so quiet I can stand next to it and not know its in cycle. The smart functions and integration with all my other LG home appliances and electronics is excellent but above all the dishes, from pots and pans to fine china come out impeccably clean. I highly recommend.

Why is the bottom rack so difficult to slide in and out? Is there a trick to it?

Asked by: djb813
The lower rack for the LG Top Control Smart Wi-Fi Enabled Dishwasher with QuadWash™, Model # LDT5678BD should not be difficult to slide in or out. Has this always been an issue with the lower rack since purchasing the dishwasher? Check to make sure that the rack is aligned correctly within its tracks or that there is nothing stuck on the tracks preventing it from gliding in and out easily...^Ivan

Does LG make a dishwasher with a heating element anymore? This new steam dry kind dont work for me. I don't like that the inside of the dishwasher is always wet and not all my dishes are dry. I just want one that has good ole heat to dry my dishes.

Asked by: debbie13
Hello Debbie13. Are you interested in a Top Control Dishwasher like the LG Top Control Smart Wi-Fi Enabled Dishwasher with QuadWash™, Model # LDT5678BD, or a Front Control Dishwasher? Most, if not all of our current dishwashers feature a Hybrid Condensing Drying System which does not rely on a heating element to dry the dishes. You can visit our site at https://www.lg.com/us/dishwashers where the dishwashers are categorized as Front Control Dishwashers or Top Control Dishwashers. Each Dishwasher has its own product page and the type of heating system is listed under features....^IFV

Apparently my dishwasher seems to be having the same problems as others. The dishwasher does not turn on, my understanding the panel needs to be replaced. I purchased the dishwasher almost 3 years ago, can LG fix the problem without extra cost?

Asked by: Anonymous
We regret to read that your LG Top Control Smart Wi-Fi Enabled Dishwasher with QuadWash™, Model # LDT5678SS is not turning on and we sincerely apologize for any inconvenience. If you have checked to make sure that the circuit breaker for the dishwasher is not tripped, then the dishwasher will need to be inspected by a qualified service technician to determine what the issue is. The dishwasher has a Limited Manufacturer's Warranty of 1 Year for Parts and Labor, 5 Years for the Control Board and Rack Parts, 10 Years for the Direct Drive Motor and a Lifetime Warranty for the Stainless Steel Door Liner or Tub from date of purchase. If the part that needs to be repaired falls within the Limited Manufacturer's Warranty as described above, it will be repaired within that warranty without you incurring any cost...^IFV

I noticed it says parts have 1 year warranty. Bought our dishwasher in March 2019 and just noticed the top rack has rust. Not happy about rust one something that is supposed to get wet. And after only 1 year? That’s not good quality. 

Asked by: ChrissyW
That's terrible! I'm looking at this dishwasher, and I now have 2nd thoughts. There is something called liquid electrical tape, that you could use to seal it the rust spots off. Its only available in red and black, though. I hope they replaced the tray for you.

Could you please tell me the difference between stainless and stainless steel? They look identical. We have a stainless steel LG fridge, and ordered a stainless steel LG range (LSD4913ST) so want to match. The SS DW is on back order though.

Asked by: LizFe
The end of the LG model # tells you: SS if it's fingerprint resistant stainless (looks slightly darker) or ST which is plain stainless steel.
