Rated 2 out of 5 by from I wish I could return it I would give anything to get my money back and return this washer- I'm SO disappointed. It's generally fine, I suppose, but LG has tried to do WAY too much and are wrecking their own products. My main HUGE issue is that I loved my old hand wash cycle on my LG washer that just broke down (after only a few years) and I was told that LG washers eliminated that cycle (WHY?) but that it was available via the "download" cycle option. Short story, it is not. Lots of totally useless cycles with no explanation. No guide, I searched everywhere online. (When I called customer service, they didn't know what the cycles meant either and told me to "google it".) "Rainy day" anyone? What? But no hand wash. The app is a huge pain in the butt. I don't really see the purpose, it doesn't work hlf the time, it isn't intuitive, and it's cumbersome. Their technology is definitely making the process MORE complicated, not less. So far, I have to turn the washer on manually to do anything from the app....why would I not just set the washer? I just want to turn a knob and choose the cycle I want. I don't need to start it from Maine. (Not that the app would work anyway) Other than that, it's too large for a one person household, and louder than I expected. The touch screen isn't backlit and you can't see a thing without shining a light on it. I would literally give anything to return this washer and get a new one and have no idea how to without eating many many hundreds of dollars. I'm stuck.

Rated 4 out of 5 by from LG Front Loading Washing Machine - WM3700HWA We purchased over a month ago, and we are very pleased with the overall operation of new LG Front loading washer. The spin cycle is a lot quieter and less vibration of the 12 year old LG Front Loader we replaced. Also, the extra options were a positive addition. The biggest negative is the control panel is hard to read with "White Letters" on a Black Background. The previous model had black lettering with a white background. Respectfully, Lowell

Rated 4 out of 5 by from First front loader, enjoy using. Machine has nice features. It's very quiet as compared to my previous top loader he machine. I have washed quilts and comforters and they came out very clean and dry. Had to put a real heavy one through a extra rinse and spin so I could adjust spin speed for extra dryness. Normal loads come out very clean, much cleaner than top loader. Only complaint is that control panel is not backlighted. Have to keep flashlight handy.

Rated 3 out of 5 by from Extremely poor instruction manual We bought this a month or so ago & we were replacing our Maytag washer that had started failing to spin out after second rinse. Because we thought that we were buying another superior washer brand, we were quite excited to get started. HOWEVER, that excitement was soon dashed when we needed to run a load of wash. I, the wife, had been terribly ill w/ some thing communicable; thus, I was not downstairs for the delivery & any instructions; my husband stood by, but apparently he failed to pick up any step by step directions if they had been given. My husband, when I asked him, said that they were just “pushing a bunch of buttons”. No problem, I thought!!!! HOWEVER, there was because the manual said almost nothing of any value; I know because I read & read & read. Because we needed to use the washer, I started just pushing buttons, trying to be logical as I went. Finally, after two or three weeks of creative thinking, I discovered what I think to be the correct manner to go about EFFICIENTLY starting a load of wash. My husband seemingly did not discover the efficient manner until sometime later or so I think after a brief chat. I want you to know that that experience really put a sour taste in my mouth. Also I right away discovered that that machine cannot wash my washable pillow, which I must do periodically. My MAYTAG washer had been able to wash it without any problems. I am a very good writer who could do wonders for your company by rewriting your manual. [This review was collected as part of a promotion.]
