What people are saying
Rated 5 out of 5 by from Great front load washer Love the front load washer, very easy to use, nice and quite don't hear it speening out.

Rated 3 out of 5 by from Hope it Lasts Longer than My Previous LG Washer I bought this washer a month ago after the previous model failed after only 2.5 years. (It was the bearings, which should have lasted around 10.) The washer works fine, and is mostly quiet. However, there are a few times when it's quite a bit louder than I'd expect, which makes me worry that something's not right, or that the problem from the previous LG washer will happen again.

Rated 4 out of 5 by from Necessary Improvements to LG Washing Machine 1. Backlit instrument panel to aid in setting up washing schedule 2. Built in light inside washing machine 3.Inadequate shining light to dial settings 4. Reversible doors that will allow right or left openings 5. Expecting the user to wipe the door gasket dry after each use to avoid mildew smell is a terrible inconvenience. Surely, you can solve this problem.

We just purchased this model and was wondering why the wet detergent fill compartment must be emptied before doing another load. Its annoying to take the tray to the sink each time to empty the water.

Asked by: blingner
I am responding to your concern based on my former washer which was a different brand.  If I overfilled the detergent or any of the compartments by even just a tiny amount, then there would be water in that compartment at the end of the cycle.  Sounds crazy, but that is what I finally concluded.  Typically I used a lot less then the maximum, but if rushing and not being as careful it did happen.

Replacing a former version of the WM3700HWA, the older model had a “steam fresh” option but  I don’t see that on the new model.  Is there a way to steam freshen items on the current model?

I cannot find details on the program cycles. What are the different cycles time?

Asked by: Ecrins
Hi Ecrins, regrettably, there aren't any cycle times listed for the wash cycles in the ENERGY STAR® Qualified LG 4.5 cu.ft. Ultra Large Capacity White Front Load Washer with Steam and Wi-Fi Connectivity, Model # WM3700HWA. Cycle times will vary according to the size & weight of the load, your chosen cycle, and options, the temperature, and pressure of the incoming water. When you load your laundry into the tub after you select your preferred cycle, when you press Start/Pause, the washer will agitate without water to weigh the size of your load & display an estimated time for your chosen cycle. The default settings for the cycle can then be changed using the cycle modifier and option buttons. When you change the default settings and options, that estimated time will change again. The estimated time is not the actual time and is based on normal operating conditions...^IFV
