Excellent dishwasher

KarenO43 12/6/2020

We purchased this dishwasher about two years ago from Costco along with the Signature 31 cf refrigerator and LG Studio gas range. We have been very pleased with all these appliances even though we are now waiting for replacement of the control panel on the dishwasher because some of the lighted elements have gone out. The support people have taken care of this issue and have arranged for a replacement as soon as the part is available. That aside we have been more than pleased with the performance of this dishwasher. It is efficient and powerful always giving clean sparkling dishes glassware pots and pans and utensils. I couldnt be more pleased.

Quiet quick dry convenient

khaysjr 12/6/2020

We elected to go with LG signature refrigerator and range for our new home. The dishwasher was just an add-on that matched. However we have been extremely pleased at all of its bells and whistles on top of the standard features that are unbeatable. It is extremely roomy quiet and efficient. We love the third row for silverware how the racks can move up or down.

LG Signature Dishwasher

Karen42 12/11/2019

This dishwasher far outperforms our previous top-of-the-line dishwasher. Outstanding performance and lots of helpful features and so quiet that the only time we hear that its running is when its pumping water out. We love the adjustable third rack and the flexibility height tines etc. of the other two racks as well. Even the interior light is very helpful. Use a quality dishwasher detergent and rinse aid and everything will come out sparkling clean. Best dishwasher weve ever had. Well worth the price.

Super Quiet - Flexible Interior with Light

One Cottage Boy 7/2/2019

I bought this to replace a 20-year old dishwasher. I am impressed with the almost total silence of the machine and the great flexibility of the 3 racks. The slightly-pebbled stainless steel exterior does not show fingerprints I thought this dishwasher was well worth the price.

Best dishwasher

Cody Lane 3/10/2019

We bought this dishwasher a couple of months ago. We had a challenge with some concealed damage during shipment which required a new unit. Once we got that straightened out then we were good to go. It did take some time to install and we would recommend that you sound proof it with the parts provided. Great performing dishwasher Awesome third rack. For top performance do the following: turn on your sink water and get it hot before running the dishwasher. Use the liquid rinse aid - this significantly helps with drying all plastic items.
