What Customers Are Saying
This washing machine appears to have mixed reviews. Many users report it is quiet, efficient, and cleans clothes well. The large capacity, variety of cycles, and reduced drying time are also noted as benefits. However, some users experienced issues like excessive noise, vibration, long cycles, and problems with water level and rinsing. There are also concerns about quality and reliability, with some machines failing prematurely. Overall, while the machine works well for many, there are enough negative experiences to suggest potential quality control or design issues that buyers should be aware of.

This washer was a replacement for an identical washer that was never that great. It leaked multiple times for no particular reason. I bought it strictly because it was a match to the stacking dryer I already had. The original lasted five years, probably around 4000 loads through it The good news is the software is vastly improved and balances the load on spin much better than the old one. For the on sale price I bought it for, I could’ve bought a standalone washer and dryer non-stackable of ...

Front loader washer
Just had it a few days but so far it far better than our top loader Maytag, I hope it shows it self to be more dependable. It is my first LG appliance.

Excellent!
I’ve been using this machine for a week and love it! No frills but flawless in what it does offer. Intentionally purchased a machine with no AI as i do not like AI being added into everything.

Doesn't Clean
Washer doesn't get clothes damp let alone wash them. Anything that's near the back of the machine comes out completely dry. I've had other LG models. Purchased a front loader so I wouldn't have to reach so far into the upright machine, but that was a big mistake.
Does not clean the clothes
It does not get most of the clothes damp let alone wash them. Shirts come out with the dirt still on them. Fleece items come out with damp areas but you can tell most of the item stayed dry. I add additional water, do the pre-wash and still have to do a repeat wash for a second time. That’s 4 hours for one load. I dont know if all front loaders do this but I am stuck with this for the next several years. Do not buy
Wish I never bought this
I’ve owned this new washer for 1 month. It was sealed in its original box and didn’t include instructions for this model. It came with a generic manual for 10 models. No information on how to use the machine that I bought. I called LG and they said they would mail me instructions and it would take 10 days. I didn’t get them. Lowes didn’t have the instructions either. After 2 weeks, I called LG again and he apologized and said he would resend express or fast delivery. Now it’s been a month, I sti...

good washer for the value
washer works like a washer should. you do have to make sure the door is closed by pushing on it and making sure it is in place. no leaks. overall a good washer. i did have to contact customer service due to the delivery service not leveling the washer or making sure it worked as per the agreement. customer service gave a $25 e gift card due to poor service.

Mixed Load of a Washer
Such a mixed load. But ultimately I would not recommend this washer or brand. 1. This washer randomly leaks. Not from the fill lines, not from the drain line. Not from around the door or visible gaskets. Load size doesn't cause it to leak, detergent amounts (suds) does not cause it to leak. It will at some random time leak enough to cause a pool and a stream in the garage. Would not recommend this washer be placed outside of a garage. 2. Door can't be swapped. I'm surprised I'm placing this as...
