Dont Buy

3900 9/5/2024

I previously owner an LG washer dryer for over 20 years. Moved to Florida and decided to leave my set with my house and purchase a new one. We purchaesd the WM3900HBA. It is less than 5 years old and I had to have the Washer machine dispenser replaced. call a local repair guy and he replaced it. Order the part from LG. Fast forward 7 months and the same thing is happening. LG only covers parts for 3 months. Unacceptable that i am replacing the same part 7 months later on a washer less than 5 years old. Poor customer service IMO.

Theres till good companies in the world

Bigdawg62 7/29/2024

I call a few weeks ago and even though my dryer was out of warranty they still sent me the part free of charge. They even made the extra effort of contacting me and letting me know that when the order shipped they would give me the tracking number. This is going above and beyond because most companies today only care about making money off the customer but this wasnt the case they actually cared.

Loved it until it started leaking.

Sky73 6/23/2024

Ive had my washer for 4 years. It was working great until it started leaking about 6 months ago. Ive had plumbers out twice to clear the underground pipe. Recently I hired an appliance repairman to check out the machine. He couldnt find anything wrong. It still leaks after every wash. The water is coming from under the machine. I dont know what to do next.

Great Features

Mfigueroa 6/18/2024

I am very happy with this washer. It has several wash options including downloadable cycles. It is quiet does an outstanding washing job and clothes come out almost dry. Its WiFi connetivity allow for constant updates on time left time for tub cleaning and finishing cycle warnings. This saves me a lot of dead time between the wash finish cycle and start of drying cycle.

leak

g2dn 5/17/2024

We purchased it about 3 years ago and it developed a leak around the soap dispenser. In fact it is so bad we have rust. We have order a LG repairman a couple of weeks ago and have no idea when he will show up.

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.
