Noisy unrepairable junk

MLJensen 12/21/2023

It started making noise about 2 years after we purchased it. I finally called an authorized repair person LG recommended and they told me that they are notorious for building sub-par machines. Its nothing that could be fixed. I just get to put up with the noise until in wears out. Ugh

Problem with steam valve on LG dryer

Steamedup 8/6/2023

The dryer and the Steam Sanitary feature worked well until about six months ago. Fortunately we bought the 5 year service warranty when we purchased the dryer. The problem was that the steam valve was not designed properly. It became blocked with hard water precipitates calcium sulfates. The valve should have been designed with a water softening pre-filter to remove the calcium compounds in the water. Without pretreatment the replaced steam valve will probably have to be replaced again in three or four years.

Absolutely awful experience.

Ricardo Alvarez 7/13/2023

Technician was disrespectful raising his voice to me. Bad attitude and unwilling to do his job or find a something. Impresive how you could send someone like that to any home. Just because of this I will never buy another LG electronic or appliance.

Love the machine. The pairing with washer and all the modes so many options. Deducted one star as sometimes loads dont fully dry but probably I need to manage the settings better.

Worst Dryer Ever

Dav12 12/28/2022

We have had this dryer for a few years now since we moved into our new home and it is the worst dryer we have ever owned. It does not dry the clothes properly and it always turns off leaving the clothes damp. Additionally the biggest problem is the lint trap that always pops out of place and snags even tears clothes. It is so bad we have decided to get a new brand of dryer and will never trust or buy an LG washer/dryer again we wont even recommend LG washer/dryers.

Good machine a little more complex than necessary

JanetS55 11/16/2022

I should preface this review by stating that this replaced my 30 year old dryer. I like the dryer and like the many options it has. I still have learning to do. I couldnt connect to my wifi/bluetooth so unfortunately I cant yet customize programs or use the app. Some automatic settings stop the machine after 5 minutes so manual drying time is necessary. The drying sensor seems to stop the machine before items are totally dry so a manual finish has been necessary. For the most part you can figure out the machine controls. Filter cleaning is a breeze. Setup was great but I had to go buy a flexible dryer vent hose because the included semi-rigid hose kept the machine too far away from the wall. I expect the operating improvement to come along with experience with the machine. Overall I am happy with the purchase.

Beware of KLARK- the LG robo-answering device

DEWA 11/14/2022

We purchased a LG washer/dryer set in June through Costco. The machines are described as Smart. The washer seems capable of doing what its designed to do. The dryer required a replacement of the Control Panel and sensors because the only way it fully dried a laundry load was on timed dry. The biggest problem was attempting to speak with a real human person because KLARK the robot answering interface was interfering and sending me to the wrong departments. Even after overcoming KLARK the person I spoke with gave me a long list of troubleshooting tips to perform none of which provided a solution. She inaccurately described the problem when she sent the repair request issue to a 3rd-party repair company which also took 2 visits to get the needed replacement parts. The service tech was excellent and the dryer seems to be working but it was a challenge. We expected a more robust response from LG.
