What people are saying

Rated 1 out of 5 by from VERY DISAPPOINTED We have owned the machine less then 4 years and it has been repaired 8 times

Rated 4 out of 5 by from Overall good washer, 4 years after purchase the drain pump failed and it wasn't particularly easy to find out how to get it serviced by LG. I ended up ordering a replacement on Amazon and changing it myself, pretty easy fix.

Rated 5 out of 5 by from Awesome Washer! I bought my LG stackable washer a little over 2 years ago. I do a lot of laundry! Approximately 5 loads a day! It is awesome! I did have to have the motor replaced, but the amount of laundry that I do, I felt it was reasonable. We are actually going to buy one for my mom!

I just washed 2 sets of queen-sized sheets on the Cotton/Normal cycle (with Turbo Wash turned off). The washer ran 57 min.  WhenI took them out of the washer they were streaked with wet and dry areas; not completely wet! What's up?

Asked by: Margie M
Hello, based on the information provided, it sounds as if the drum was overloaded. Depending on the size and thickness of your items will determine how much can be placed in the drum. Load clothes loosely , and do not overfill the drum. Clothes need room to circulate in order to get clean. Do not press down on items while stacking them in the drum. You can also use the Heavy Duty or Bulky/Large cycles as they add the most water. ^AC

I have only 80 degree tap water available in laundry room. Will this machine get water hot? Can I still use steam features?

Asked by: zguillory
To provide optimum washing performance, it is recommended that the hot water temperature for your gas of electric water heater should be set at 120˚-135˚F (48˚-57˚C) and the cold water at 60˚F (15˚C) for the ENERGY STAR® Qualified LG 4.5 cu. ft. Ultra Large Capacity TurboWash® Washer, Model # WM3770HWA. YOu will not be able to get hot water if your water is only 80˚F (not sure if your temperature is ˚F or ˚C˚?) If it is 80˚C then that is 176˚F. Water turns to steam at 100˚C (212˚F) at standard pressure. At lower pressures, such as atbthe top of high mountains, water boils at a lower temperature than the nominal 100˚C (212˚F) and if heated further, it becomes superheated steam...^IFV
