What People Are Saying

Rated 1 out of 5 by from Severely disappointed We bought this machine just over a year ago. 9 months after buying it, one of the bolts shears off inside the drum. I was able to get the machine replaced through LG (took over 6 weeks to do this) but then within 6 weeks of getting the new machine the EXACT same thing happened to the new machine. Although they are offering a replacement again, it has been another 6 weeks of sorting it out to get to this point. I am severely disappointed in this washing machine and severely disappointed in LG's customer service. I chose LG because of their product quality and I am so disappointed. I wouldn't recommend this machine at all and am looking at a different company for my replacement washing machine.

Rated 3 out of 5 by from Controls a pain The controls appear to have been designed by the same group that designed those black digital watches and VCR's. Issues: My old washer, I set the controls and almost never changed them. I pushed one button to start the cycle. This one, I have to -- manually select the desired wash style (Normal) --On a display with 15 or so other wash options which require reading glasses to actually read. --then find the cold wash and rinse buttons and select it every time. -- then start the machine --And I need a device with NFC to program a setting which may or may not allow me to only push one button to get the settings I want? There was no Human Factors/Usability work done with this device. I would not have thought it possible to make a washing machine which was a nuisance to use , but LG has managed it. The 10 year warranty for direct drive is for parts only; labor typically makes the cost of repair prohibitive. So I discount it as a marketing ploy. I have no idea on the quality, ask me in 10 years It does do what I expect a washing machine to do , clean clothes.

Rated 4 out of 5 by from So silent and efficient! Best reviews online are deserved! My clothes come out cleaner, brighter and keep their shape better. Why do we wait for the old washer to die before buying a new one? Don't know why we can only use HE (high efficiency) detergent with this machine, but I'll stick to the LG rules because this machine is a gem! I was reluctant to go for front loaders (childhood & landromat memories of doors with bad seals!) but all reviews says these are the best so we tried. Now, I am waiting for the electric bill. Hopefully we save a bit there too?

Rated 4 out of 5 by from 2nd LG washer Fast cycles. Easy to install. I love the little song when a load is finished. I wish the door was clear so I could see inside but other than that I love this unit .

Rated 1 out of 5 by from Poor Quality Poorly Designed I purchased this machine as it has a great allergy washing cycle and is also highly customizable. It also is one of the few washers with 3 rinse cycle. It cleans fairly well but needs more water for the rinse cycles. In addition and more importantly, I have had this washer for less than two years and the cold water intake assembly failed which caused this washer to leak very badly. Needless to say, I am very disappointed as this is my second LG washer...My first never had any issues and perhaps I should have kept it! My issue began immediately after purchase when I found out that new LG washers experience "water hammer" issues as they do not have built-in arrestors. The replacement part is totally redesigned which indicates that the original part was flawed. Nice going LG and thank God I purchased the extended warranty!

Rated 5 out of 5 by from Glad I made the purchase! I was looking for a washer that could do my comforters. This machine washes them with no problem and I'm saving money by not having to wash my comforters at the cleaners. It also did a nice job at washing my wool winter coat on the delicate cycle another money saver! Great investment!

How to remove mild dew from the rim of the door on the LG washer? 

Asked by: Aparna
We regret the trouble you have experienced with this washing machine. It is recommended to leave the washer door open after each cycle. It is also suggested to wipe down any wet surface to prevent water collection, which can result in mildew. If mildew has already begun developing, it is suggested to run the TUB CLEAN cycle with some bleach. If the mildew is on the door, then clean the door with diluted bleach on a cloth. If additional assistance is needed, please contact our Customer Interactive Center at 800-243-0000.
