Customer review summary generated by AI, including incentivized reviews.Broke after 18 months
After about 18 months of normal, residential use, the plastic frame that holds the lid in place cracked. We do not store anything on top of the washer (couldn't, anyway, because the lid is slanted) so there is no explanation as to why this cracked. This is preventing the lid from aligning correctly and locking, which does not allow the washer to operate. Warranty expired after 12 months - service fee is "from $369" for repair with unknown timeline. Waste of money and will not purchase anothe...

Great washer.
I got this washer a few weeks ago and has been nothing but great. The heat works well and I find that it has great calibration when sensing the load cutting time down! Only thing that bugs me lil bit is the high frequency that comes on it when it starts to move. I do choose to close the door to my laundry room

LG = Long delays Gauranteed and dirty clothing
If you work for a living and get dirty, this washer is NOT for you! If you cook and get food or oil on your clothing, this washer is not for you. If you are an office worker without pets and willing to wear a plastic bib when you eat, this may be for you!! We got a pump failure within the 1st 20 months, and it will be 2 weeks or more before it gets fixed by LG. Yes, LG says they need to wait for the part. So the water stuck inside will probably be nasty by the time they return. Not that th...

Terrible design and cheap parts
Do not buy this washer. It has great features like large capacity and an agitator. BUT it has a cheap chintzy low quality detergent distribution container that breeds mold!! Totally unreasonable for a top loader. This detergent distributor slants back so it retains liquid and you have to remove it to dry it. Plus instructions state you have to remove it to clean it. Try to remove this cheap plastic part!!! You have to force it out of the washer - depress the cheap plastic tab then jiggle the ...

Terrible
The washer overflowed due to the valve not shutting off. Flooded my house at 3 am and when I claimed warranty they were rude and still haven’t fixed my washer. It’s been broke for a month.

Good luck
Bought it in the 3rd week of May 2025 from Lowe’s. It developed a horrible grinding sounds and stopped draining water in the 3rd week of June 2026. At First, LG representatives said they’d honor the warranty, and would promise to call, email or text me with an appointment time for said technician to come over within 48 hours….this exact conversation happened with every rep for 7 weeks, I kept copious notes with names and date stamps. It was crickets for 7 weeks….and I was always calm, cool and...

HATE IT EVERY WASH - Regret buying it
I loved my last LG washer but couldn't fix it, so I considered no other brands. I regret that. I hate this machine! The black glass lid is very difficult to see through. Nothing will stay on the lid because it's slanted. I can't sort or fold clothes, put my laundry basket or anything else on it. Shortening the front doesn't mean the lid couldn't be level. NO SOAK, rinse temp, or functional spin only options. NO delicates, towels or other common cycles. They have to be downloaded; but, only 1 at ...

Great , washer. Question the button style
So far, it has been a great washer, quick and quiet. The only issue I have is the power and start buttons are very subdued and hard to find.

Destroying clothes, Lowe’s said to bad
I bought the washer and dryer and have had for two weeks. It is snagging and ruining my clothes and bed sheets. I brought the clothes into Lowe’s and was told since I had it for more than 48 hours it is my problem. LG wants to send out a tech to look at it, at this point one of these companies need to step up and replace the units. I had a Samsung for 10 years with no issues and I’m disappointed that I decided to switch. Whatever you do, do not buy from Lowe’s or LG they both have horrible ...

Black Flakes OnYour Clothes
My LG washer is eighteen months old. Very shortly after it was purchased I began seeing black flakes on my clothes. I replaced an LG washer and dryer with this new set. I never had this trouble with my old set. I use my tub clean once a month and always leave the top load lid up when not in use. The black flakes finally got so bad that I requested a repair visit. The repairman showed me all this buildup under the tub of the washer. The repairman cleaned off what he could of the black gunk (it l...
