A Convenient Spot for Hard-to-Fit Items

From flatware to long-handled utensils to small espresso cups, items that may otherwise need to be washed by hand finally have their place in the dishwasher. The convenient 3rd rack holds more items so you can save time and wash fewer loads.

So Quiet, You Can Use Your Indoor Voice

Now you can run the dishwasher whenever you want—day or night. The 46 dB cleaning cycle is whisper-quiet, so you won’t have to worry about interrupting post-dinner-party conversations or naptime. Especially important for homes with open floor plans where sound readily travels from room to room.

Rated 5 out of 5 by from So quiet! I love this dishwasher. Love the fact it is so quiet i can easily watch tv and never even know it’s running. Also like the fact that it alerts my phone when the cycle is complete!

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
Hi LizFe. Stainless and Stainless Steel look identical because they are one and the same. The Stainless Steel on the Top Control Smart wi-fi Enabled Dishwasher with QuadWash™, Model # LDT5678ST and on the LG 6.3 cu. ft. Smart wi-fi Enabled Dual Fuel Slide-in Range with ProBake Convection® and EasyClean®, Model # LSD4913ST is the same Stainless Steel...^IFV
