Four Reasons to Buy an LG Dishwasher


Put Enhanced Cleaning in Motion

Achieve maximum cleaning throughout the entire cycle with LG QuadWash . With four spray arms instead of two, QuadWash also includes Multi-Motion arms that rotate back and forth while spinning. The high pressure jets power-clean dishes from multiple angles.


Think you have to check on the dishes" Think Again

LG smart dishwashers come with SmartThinQ® technology built-in, so you can get smartphone notifications when a cycle is complete. That means less waiting and more time to yourself. You can even check on the cycle status with voice commands using the Google Assistant and Amazon Alexa, so you don't have to lift a finger.


Count On It

When you buy a dishwasher, you want something reliable that you can count on. Because the Direct Drive Motor uses fewer moving parts and operates more efficiently, LG confidently backs the motor with a 10-year warranty.


Easy Loading & Maximum Flexibility

The newly-enhanced EasyRack Plus system provides outstanding flexibility and convenience, adjusting to just about any load of dishes to help ensure optimal cleaning performance. Easy to adjust on-the-fly, this racking system can shift to handle any challenge your dishes can serve up.


Quiet Operation

LG's technological advances, like the Inverter DirectDrive motor and the advanced self-cleaning filtration system, were designed with quiet in mind. At 44dB, this dishwasher is among the quietest dishwashers in its class.

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.

Well thought out but not reliable

Roger E 8/22/2022

Weve now had the unit for almost four years Dec of 22 will be 4. It generally works well and has nice features silverware rack for example and adjustable height of the middle rack. Shortly after we bought it within a couple of months the control panel plastic surface split. I called LG and they told me that it was a cosmetic issue that did not affect performance and was therefore not covered by warranty. See photo.. I felt that it was a potential place for moisture to get into the switches in the control panel and cause failure and felt that it should have been replaced. The middle and bottom racks experienced corrosion one has been replaced under warranty. See photo of middle rack corrosion. They told me the 2nd was going to be replaced but it hasnt come yet - Ill have to call them back and find out where it is. If you get they idea that Ive spent more time on the phone with LG support you would be correct. And there are more issues. One is that the dishwasher develops a funky odor if you dont leave the door open after it runs to let it dry out thoroughly. Our last dishwasher was in place for 20+ years and never had this issue but washing machines tend to do this.. I do clean the filters regularly and run the cleaning cycle per instructions when prompted by the machine. The cleaning cycle is actually a GOOD thing - you simply put a cup with 8 oz of white vinegar in the top rack and run the cleaning cycle. No purchasing special washing supplies. Anyhow doing these things doesnt prevent the funky odor - only leaving the door open after running for a while so the interior can dry will fix that problem. Finally our latest issue is that the unit pauses itself midway through the washing cycle. A pause per the user manual is what happens when you open the door midway. The white LED on the front of the unit blinks indicating pause vs. on solid indicating that the cycle is on and running. You then have four minutes to restart it or it just shuts down and you have to restart. SO if I hear it beep when it pauses it beeps several times then I just open the door it start close it and it runs to completion. The issue is now I have to stick around and babysit the dishwasher to coax it through to completion. Better than washing them all by hand I guess but not what Im looking for in a dishwasher. So Im afraid that I cant recommend LG dishwashers at this point. Im hoping others are having better luck now. Remember that our unit was new in the fall of 2018.

Control panel non operating cant get assitance

memphisgal 3/21/2022

We bought a house with this dishwasher. We were told it was two years old last year. The control panel will not come back on after a power outage. I have reached out trying to get assistance. I cant get past registration information that I dont have. Previous owner did not pass on any information . I have tried to use the online manual with no success. The light is on in the dishwasher so I know it is getting power.

Worst After Sales Service

Barney Patel 3/2/2022

I bought this dishwasher in a set along with the gas stove refrigerator microwave and washer dryer. The dishwasher started giving an OE error message so we called for repairs and support. There is no service in the Buffalo area. The closest service person is in Rochester and can only come on April 6h - almost 40 days after our call. PATHETIC. Worst mistake was not to check if they LG can provide after sales service. Worst decision I made. I wish I had opted to but another brand.

It keeps breaking after 2 years

Wow so unhappy 1/5/2022

Ever since we got this unit its been nothing but issues. For a year now we use a chair to keep the door closed. Our motor just went out and we got that and the door repaired again and a few days later the door will not stay shut. We haveasked for a new unit thinking this was a lemon but no way.
