Professional delivery and/or installation is available for the majority of our appliances. For more information, contact us at one of our locations.

Extended warranties are usually very inexpensive and can save you thousands in the future. Some can even cover extra costs that result, such as cost of food that spoils when your fridge dies. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Appliances can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new appliances should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

Dishwasher good customer service terrible

Alfie9 2/15/2024

We went thru the LG website to purchase this dishwasher and selected the retail for delivery and installation. The main reason was the $200 discount from American Express using my credit card. The final price was $1400 +/_. We called LG several times and received the same explanation. Not buying from LG even using website without selecting a retail directions voided the offer. Will not consider LG e-mail offers.

LeeC unhappy cuetomer 2/12/2024

I bought this dishwasher back on Nov12th it didnt get installed until Dec 4th. It was installed with a crushed drain hose and wouldnt drain. I called and reported the issue and after 2 attempts to repair the dishwasher I had them remove the new and reinstall my old one. Now its been sitting in the garage for almost 2 months waiting on LG to approve a new replacement I heard LG product was good but their customer service is not

Bad

JDC10 2/6/2024

Appliance is less than a year old. Continues to trip breaker. Been waiting for support tech for over a month to repair the unit. Support tech has stopped reaching out and no response from LG. Terrible customer service on one of their top of the line products

Knocking sound couldnt be fixed

Marie Svet 1/18/2024

Overall this is a great washing machine. However there is a knocking sound with heavier loads that the technician believes is the drum hitting the wall. This started about a year after we purchased the product and has gradually gotten worse. Thankfully we had a warranty but after multiple visits from the technician and replacing the entire suspension system they were unable to repair the unit. Im hesitant to buy any future LG products because this was quite a hassle.

LQ features/functionality and performance

Act1 1/1/2024

After 2 weeks of use we are pleased to find how much better the LG dishwasher is over the unit we replaced. The very quiet operation lighted interior resulting clean and dry dishes and the overall fit and finish standout. Also the features and options we can select allow us to control everything to produce clean glasses pots and pan and do it efficiently.

David Ott 4/18/2023

We were using a portable machine until our kitchen remodel was done. Really liked the features and the black stainless color. Love how quiet it is and it does a great job cleaning. Looks really nice with the new cabinets. We have other LG appliances and have had really good luck them.

Why waste your time and money on other products

Ranger_ak 4/17/2023

We have shopped around and tried other name brands but one thing that is certain we ALWAYS come back to LG products. From TVs washers dryers microwaves and Frederators....dont waste another dollar or minute of your time. This new dishwasher is absolutely the best we have ever owned. Its fast quite and cleans the dishes the first time .

Installation questions

TRSKLN 4/10/2023

We just purchased an LG Thin Q model LDTH7972D. Weve not owned a top control dishwasher in the past but it seems odd that you need to open the door perhaps mid-cycle to access the controls or even see the remaining time for the current function. I suppose this protects the panel. There are 3 small LEDs on the front just above the handle. I find no reference in the manual as to their function. Any ideas?

Nice dishwasher

DTL510 4/3/2023

Ive had this dishwasher a couple weeks and love it. The issue I have run into is that the very top rack sometimes get caught on my 12 oz glasses or items of that height. I have to make sure to put them on the right side of the rack as the top rack comes up a little bit higher on the right and they will fit on that side.

Outstanding dishwasher

Mamabear82 3/25/2023

I love my new dishwasher. It has 3 racks. I put silicone utensils scissors spatulas and other odd things on top. The middle rack adjusts to hold my tall glasses and coffee travel mugs. The bottom rack fits two dinner plates side by side. I couldnt do that in my old dishwasher. I can load way more plates and bowls than I could before. It has a light when you open the door just like an oven. The silverware rack has slots for spoons that really helps me wash more silverware at once. I dont know how this dishwasher could be any better
