Horrible LG Experience

Rock7 2/7/2024

After cleaning and drying my gasket in my front loader machine I still developed mold on my gasket. LG has promised to replace this gasket free of charge but every time I call no one can find the call that promises to replace this. LG does a horrible job in taking care of their customer issues with this front loader machine

Ok machine 1/19/2024

Good customer service comes with the machine. If anything goes wrong the customer service rep will try to resolve it over the phone. If it cant be resolved a tech is sent out to fix it for a flat fee. The machine cant get 5 stars because when I had my previous machine from a different company I never had to call customer service for anything and I had it much longer. This machine has to come with good customer service because its not built as reliably. Sending a rep out to fix it or ordering parts is not free. Company is making money off the machine and the repairs like a car. Machine is very quiet and washes clothes well.

Buyer Beware

Breaking up with LG 11/24/2023

This was the worst LG product I have ever bought. I have always supported LG and have loved their products...until I purchased this washer. It leaks. I have replaced the dispenser but it still leaks. I have contacted LG and they refuse to replace the defective dispenser even though they admitted to a manufacturing defect. I contacted customer service many times but got nowhere. LG wont even back up their product. In addition the door to the washer has stress fractures in it I can only imagine the mold and deteriorated floor under the washer. I refuse to replace any part of this washer because the replacement part cost too much. The washing machine is not worth saving. I am currently looking to replace the washer. Unfortunately I wont be purchasing LG. DO NOT purchase LG.

WARNING DO NOT BUY

Clubhouse 10/4/2023

This product was purchased June 1st 2019. Not only did the Gasket break after two years the motor went out and the tub leaks from underneath at this point it has been a money pit to fix it. The parts to replace are absolutely ridiculously priced. 10 out of 10 would not recommend

Very poorly made wont even last a year

katieking0412 9/28/2023

Purchased 3 years ago it had to be rebuilt after 6 months then broke two more times over the next year and a half and had to have it rebuilt. The last time was 3 months ago and once again its broken 4th time in 3 years. It is a lemon and our last set lasted 15 years with no promblems. Very disappointed and disappointed that LG wont stand behind it and completely replace the washer after weve been very happy customers for 15 years until this washer.

Door Seal needs design improvement

NJ_apple 6/5/2023

Door seal only lasted 3.5 years. Technician repair was installed improperly and had to have him return for another door seal repair 1 week later. Detergent tray locking tab was broken and technician ordered the wrong part. Totally frustrating

Machine is fine . . . if you dont get a lemon

mew33 5/15/2023

Bought this unit 3 years ago. Not long after we started using it we noticed a little bit of black sediment at the bottom from time to time. We thought that was related to the venting of the dryer. But when we had the vent cleaned a couple months ago we were told it had nothing to do with the dryer and was likely from the washer. Approximately a month or so ago the sediment became worse and the washer started making more noise when in use so we stopped using it and tried to get it repaired. Long story short . . three weeks and two technicians later we found that the inner tub isnt balanced and causes the unit to shake which caused a whole lot of other issues. Manufacturer defect? Probably. But not under warranty so now were looking for a new washer. Likely not an LG which is too bad as we liked it. But cant risk this.

Simply the best choice in a new washer.an dryer

SLHayden 4/3/2023

We bought both the washer and dryer plus pedestals. Our old units were about 10 years old and were working fine but very noisy. The LG was ranked very high by CR so we bought them. They are soooooo quiet They seem to wash our clothes better. Both unit will tell me by phone when they are done and if the lint trap needs to be cleaned. Overall it has been a wonderful decision.

golden_amanda09 12/28/2022

We bought this a few weeks ago and love it Its so sleek and relatively quiet. Fits our king size bulky comforter and came with a stacking kit. App functionality is also great Only downside was it was hard to modify settings on n certain preset programs. Other than that would recommend

I bought this 3 weeks ago. It has nice features however my problem with the machine is that the inside smells. Ive tried a lot to get the smell gone and its still there. At first it was a chemical smell. I tried the tub clean feature. It helped a little bit but the smell changed to dampness and unfresh.

Lgwasherguy205 11/15/2022

Its still too early to tell. This is my first front load after a life of top load. It seems every few washes you will have to drain the washer reservoir. Not sure where this water comes from but it may come during the wash cycle. Plentiful speciality load cycles

Ratified Decision

Brad in Idaho 11/14/2022

Costco had a great deal on the LG washer and dryer. I jumped for the deal. Costco included delivery and setup too. I added a LG refrigerator to the order as the three appliances were for my vacation condo 100 miles from primary residence. WOW. The features are great. And The learning curve was simple. I have actually run 4 loads of laundry so far. So far great

Happy with the washer

SmartLGBuyer 10/20/2022

Turned out to be much better than I thought. Noise is tolerable if its positioned properly. At the end of the cycle it makes booming sound for a minute or two to stop. If you dont leave the door open after the wash itll stink. Settings for cycle are various. You dont have soaking cycle option compared to top loader.

Its soooo nice to have clean clothes again

Momster again 10/18/2022

Had a top load water saving machine that I should have put out to the curb a long time ago. Granted there was a learning curve for the amount of soap you had to load but I never felt that the washer was getting the top of the clothes wet much less clean. I love this washer I dont have it hooked up to Wi-Fi or use any of the higher tech stuff. I dont see the need but maybe Ill play with it later. Right now Im rejoicing having soap free clean clothes and bedding
