TrueSteam®

LG TrueSteam® saves the time and headache of prewashing or rewashing dishes by hand. A blast of steam at the start of the cycle penetrates and dissolves tough caked-on food, but is gentle enough for your favorite wine glasses. A second blast during drying helps eliminate water spots by up to 60% 1 - no more having to wipe spotty glasses before guests arrive.

Image Feature

QuadWash™

The QuadWash™ with Multi-Motion spray arms combined with the Inverter Direct Drive motor power cleans dishes from multiple angles to reach every nook and cranny.

Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

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.

Never buying another LG

JadeJL 11/2/2024

Dishwasher had issues within 2 years. Trying to get the appliance serviced was a nightmare. This is my 3rd LG appliance and 2nd experience with trying to schedule service. Wasnt worth my time to go through various customer service agents to properly diagnose and schedule service. I ended up replacing this appliance with a non LG appliance so it can be serviced by independent repair companies vs going through LG. A lot of independent repair companies will not repair LG.

Had to fix after 2 years

Jane Gon 9/6/2024

Rubber hose connector that pulls water to the upper two levels deformed after 2 years stopped supplying water up and prevented the lower arm to spin. We called LG support but they were useless. Googled ordered the piece and replaced ourselves. The machine started washing as normal Spent around $100 for the detail only. No idea why the hose connector deformed or when it happens again. the dishwasher is quiet spacious washes well until it doesnt.

Love the dishwasher but it wasnt installed

Jenford5118 8/20/2024

I purchased the dishwasher online from LGs website. I paid for delivery and installation. When it was delivered the driver said they could not install the dishwasher as there was a small corner cabinet that increased the run from the dishwasher to the water and drain the standard size hoses they had were not long enough and they didnt carry any longer hoses on their truck. So they unboxed it and left in the garage. We had to get it installed elsewhere. It took weeks to get a refund of the delivery fee. 3 contacts with customer service numerous contacts with the social media team on X finally got my refund processed. I love the dishwasher but the installation issue which could have been avoided by just carrying the longer hoses on the truck overshadowed that.

When Quiet Counts

NonnaAndPop 3/2/2024

A couple of years ago my husband and I downsized and sold the home we raised our children in. We moved to a warmer climate and bought a condo half the size of the place we called home for over 30 years. The condo came with a perfectly working somewhat updated dishwasher. The first time we ran a load of dishes it sounded like jetliner engine and a locomotive all rolled into one. We knew right away that our first purchase had to be the Quietest dishwasher available. After some research my hubby said Get this LG and boom quick online order and viola peace and quiet in our 890 sq ft retirement nest. Thank-you LG oh and the dishes are really clean too and I keep track of everything through the online app. Great convenience and efficiency is our new Quiet dishwasher.

Poor design and poor dry feature

Patty33 12/31/2023

The bottom rack is so terrible designed. Its like a divider row is missing or something and dishes fall over without proper support. And it literally does NOT DRY. It will be days and still I will pull out dishes that are wet. This was an obviously brand new machine when we bought our house just 18 months ago and I cannot stand it.

Extremely Poor Customer Service

Distain4PoorS 12/11/2023

The motor failed on our dishwasher 5 weeks back. LG has done a very poor job with the customer service front. They keep punting to one of the appliance repair companies that they referred us to. The service tech that I have been able to communicate with tells me that LG did a poor job of providing the necessary information to get the part that needs repair. Bottom line after 5 weeks so far: our dishwasher still doesnt work the new motor was installed the service company ultimately had to order without LGs Letter of Authorization process the motor failing made the controller failed estimate to replace everything now is $1000+...still no resolution. Pretty horrible considering we paid $1800.00 on this dishwasher.

Not to Typical LG Standards

Lesley72 11/11/2023

Weve had this dishwasher a little over a year. The first week we had it a wheel broke off the top rack the plastic piece completely broke in half so no fixing without replacing. Its been great since then until a lower spray arm broke off the bottom this past week. The parts seem cheaply made for what we paid for this dishwasher. We bought this dishwasher early 2022 from Lowes. We waited several months to be delivered received in August 2022. We bought all LG appliances for kitchen and laundry based on our previous experience with the brand. However the dishwasher is probably our least favorite. Im not sure we have a warranty as i had spinal surgery shortly after we received the dishwasher. Why we should even need a warranty to fix an appliance this new puzzles me. Stand by your products.

Try something else.

Ethan Linstrom 8/19/2023

Nothing but problems with this machine. Heating element died 18months in. The water still gets hot but the drying feature doesnt work. Mildewed smelling dishes. Replaced the front control panel last month due to errors being placed after every wash. Drain feature works really well manually. Old water doesnt seem to get sucked all the way out after a cycle. Very disappointed.

Perfect upgrade and replacement

StephenCypress 4/21/2023

Our last LG dishwasher lasted 8 years and were looking forward to another decade with a quality system. To have the new features of interior lights quad wash and steam are significant upgrades to our last unit. Its also very Geoff to have so much flexibility when it comes to rack placement. Who knew doing dishes could be so much fun?
