This washer truly is a champ!

Pros: - Washer is ABSOLUTELY SUPERB at washing and rinsing clothes!- Uses VERY little water and still manages to get clothes sparkling! - HUGE capacity!- Sanitary and Bedding cycles are great! - I find this washer to be SUPER quiet...even on the highest spin speed setting! Not Game Changers for us but things to consider: - I found there was a learning curve when using this washer. Not a Òset it and forget itÓ type of washer. But only took me about three days to figure out and I feel itÕs really worth it! (Seriously....VERY trivial) Cons: - Brightest Whites cycle is a disappointment....canÕt select Extra Hot water. Better off using Sanitary or Allergiene cycles for whites. - Cold Wash option is useless....as I can simply select Cold as my wash temp...would MUCH rather this had been a soak option instead.- No light in washer - Cannot stand the tinted windows Verdict: Aside from very minor caveats, this washer is truly excellent for the purpose it serves!! You should seriously consider giving this washer a look when shopping for one! We really love this LG unit and it truly fits our needs quite well!

Not enough water

I bought the LG steam inverter direct drive washer and dryer. The washer is HORRIBLE!!! How can the clothes wash if there is not enough water in it. The clothes still smell dirty and has a strong detergent smell like it was just thrown onto dirty clothes. All of the clothes donÕt even get wet. I cut the amount of clothes I put in the washer in half and they still smell.. I hope LG fixes this problem. I understand the point is to conserve water, but if I spend this much on a washer and dryer I donÕt mind having a little bit more water in the washer. I had such high expectations and was severely let down. If this is the type of products LG puts out, I will not be buying another. Now IÕm contemplating buying another washer to replace the one I bought just 2 months ago

Great washer! Really happy with purchase

I have had the washer a couple of months now. Mostly good things to say about it!- The cycles are pretty fast. The fact that the cycle duration is based on sensing the load is huge plus.- Cleans well- Fairly quiet. Certainly a lot quieter than the machine I replaced.- Lots of pre-programmed cycles -- more than I can use. Haven't felt the need to download additional cycles.- People have complained about the display. I personally find it easy to read and it provides me a lot of information.- The ability to leave the door open a bit after a wash is a huge plus. Hopefully the air circulation will help prevent mildew.- The cell phone integration is actually useful. I often forget that there was something in the laundry, and I have left wet clothes in there for long period in the past. The phone alert of a cycle completion seems to reduce the chances of that happening significantly.What I didn't like:- The app is clunky to setup. I think it could be significantly better.The real question of course is the reliability, and I wouldn't know that for a while to come.Additional point: I bought it from Costco, which uses an independent firm for the delivery and installation. I have nothing but high praise for the installation process. They kept me informed about the time windows on a frequent basis, the truck arrived here on time, and the installers were extremely courteous, careful, and efficient with the installation process.

Performed as Expected

Purchased LG Washer on Black Friday. Delivered & Installed February 29, 2020. Did ALOT of research online and spoke with salesmen at 3 different appliance stores. The LG WM3900 offered the variety of cycles, water and spin options that I wanted, but the clincher was the drain pump filter located on the front of the washer which is easily acceptable. The washer has performed as expected in the 1&1/2 months of use. The load capacity is large. I have washed a full size comforter. The spin cycle results are excellent. The Smart LinQ app is helpful as the wash-times are different depending on the cycle (Great reminder). Cycle selector light is easily seen. Washer is not on a pedestal. Washer does not vibrate. Washer does not leak. Water drains completely. Noticeably soiled clothing cleaned as expected. So far, so good!
