Poor quality and poor customer business practices

Mike01010101 10/27/2024

Used a little over a month and started to leak from bottom of door. Troubleshooting process with chat robot wasnt so bad but then I was annoyed when a human made me repeat the whole troubleshooting process before being referred to a company to do a repair under warranty. The technician came out and quickly determined a problem and solution and said itll be 5-10 days before getting the interior door replacement. A week later the technician updated and said the parts on backorder and it will be at least 2 more months to get the interior door. Its not the repair services fault but at what point does LG recognize waiting over 2 months to repair a product owned and used for barely a month is ridiculous and offer a full replacement? The poor rating is mostly business related... didnt use the dishwasher enough to assess its abilities besides to know it quickly sprung a leak.

Cleans well but NOT quiet

hilmar2k 9/8/2024

I was looking for a replacement dishwasher and because of my home layout wanted/needed one that was very quiet. Well this is not it. This at best is an average dishwasher in terms of sound level. Very disappointing. As for everything else its excellent. Capacity is crazy. You can just keep loading it and loading it. Features are great and the controls are intuitive. Unfortunately the sound level lets its down. I would not have purchased it had I know how loud it was. Bad job by LG on that.

3 Great Things About this Dishwasher

VAuthor 9/3/2024

Here are three great things about this dishwasher 1. It does wash and dry dishes in about an hour. I use the high temperature wash which adds a few minutes more. 2. Generic store brand dishwasher tablets work just as well as national brands but are less expensive and 3. Its incredibly quiet. This dishwasher also has lots of good features and I highly recommend it. Im glad we bought it and would buy another one but I anticipate this dishwasher will last a long time Thanks LG

Highly Recommend This Dishwasher

GG707 8/23/2024

Overall this is a great dishwasher. Very quiet with superior wash drying capabilities. The one hour cycle is a nice feature with very good results. The racks allow for large capacity loading. I would like to see slightly more room in the upper most self but not a major issue. An interior light would also be a useful addition. I would also recommend an additional option for the location of the discharge hose other than the bottom left or right side. Some kitchens have services supplies lines or studor valves etc which require the discharge hose to be positioned higher making the dishwasher install somewhat tight and adding to the installation time requirement.

Great dishwasher

Jes12 8/13/2024

I recently upgraded to the LG dishwasher and overall its been a great addition to my kitchen. The 1-hour wash and dry cycle is a real game-changer when Im in a pinch and need clean dishes quickly. For drying the Dynamic Heat Dry technology does an excellent job speeding up the drying process while ensuring that plastics are not melted which is a common issue with some dishwashers. I really like how quiet the dishwasher is. Overall this LG dishwasher is a great choice for those looking for a combination of speed power and smart features in a quiet and reliable appliance.

Good Dishwasher Except Missing Tub Light

Envarcrh 8/4/2024

We got this one to replace an older nearly identical LG dishwasher that had lost the long battle with my ankles running into it when the door was down ouch.This one has one or two new features except it does not seem to have an interior tub light. I probably assumed they all did. Bought it online from an orange big box store. The product description on their web site says it has an interior light. I didnt notice it until after 48 hours so could no longer return it. I also has a strange click in the door hinge when you raise the door up to close it. Otherwise dont get me wrong this is a nice energy efficient unit and I have always like the ThinkQ app. Just not sure what to do about the missing interior light.

I am a friend of an LG employee and I received this product for free in exchange for my honest review. All opinions expressed in this post are personal and should not be attributed to LG. It is a great product It is very quiet and does the job. Dont forget the rinse aid which affects dry performance. You can use LG app to download cycle and remote start. Also it looks cool.

Quiet and efficient

IJA3 7/14/2024

This dishwasher is quiet and efficient. I love that you can customize the washes into 3 different zones. It has a top rack for up to 12 place setting of utensils. I can wash my stemware as well Its wifi capable which is so convenient because the mobile app allows control of the dishwasher remotely enhanced settings control and notifications about the wash cycle. We were able to connect it to our Alexa so we get voice announcements too. Best dishwasher I have owned yet

Great overall

Anna Z 7/12/2024

I am very pleased with this dishwasher. It dries very well with the high dry boost option and is extremely quiet. Loading is easy and the top shelf for kitchen utensils is a great bonus in addition to the standard rack on the bottom shelf. All shelfs roll out very smoothly even with full load. It also has a 1-hour cycle which I used for smaller loads and it worked great. Additionally I used the night dry option which is perfect for us as we tend to leave it overnight especially if I run the dishwasher late in the day. The app is easy to use and comes in handy especially when I forget to start the cycle and am already in bed. The 1-hour cycle is efficient and only increases to 1 hour 33 minutes or 1 hour 43 minutes with high dry boost with extra drying time which is great if the dishes are not too dirty. Overall this dishwasher has exceeded my expectations and has made kitchen cleanup much more convenient.

Awesome machine. great features and design

Birdhunter Paul 6/27/2024

I purchased this dishwasher during a sale at Home Depot during labor day. Upon delivery I was impressed by the additional care that designed into the packaging to prevent damage from shipping. I did the simple installation which took about 45 minutes. The construction is well designed both interior and exterior. A few of the control features are a little confusing otherwise nice design. The racks are adjustable roomy and well built. When operating the machine is very quiet except for the turbo mode. An additional nice feature is the ability to download wash programs using the app. The app is simple yet functional. Originally we were looking at new dishwasher with a $600 price limit. Most of what we found seemed cheap and poorly designed. We saw this machine floor model and was on sale for $678. We couldnt believe all the features and quality for less than $100 more. After verification of the price we purchased it. In a nutshell this is a great machine for an awesome price
