What People Are Saying

Rated 5 out of 5 by from I am completely astonished I will be honest. Every time I see these washes with front door I always thought these are useless... Well LG, surprised me. I got this washer, plus the dryer and the mini washer last Black Friday. Before to decide which one Buy I review every single review on line and technical details that I don’t complete understand. Finally I got this one but I had not too much faith on it. First thing I washed, was a white comforter. I so surprised, I had never seen my comforter so white and clean. This washer changed totally my mind about this front door design. Now I love my washer, I am so glad I chose it! Totally recommend. Btw, I’m not working for LG

Rated 4 out of 5 by from Cleans well, but gets off balance during the spin Even when we'll leveled, while in spin cycle the washer is off balanced with a normal load.

Rated 2 out of 5 by from Can't wash without water I bought this about a year ago and I can see why people do not like front load washers. I am in the commercial laundry equipment business and do not understand why manufacturers are not able to take cues from their commercial lines. Brand does not matter. Soap needs to mix with water to wash something. It helps to flush out any soil you can prior to the wash bath. My clothes are not even wet before the soap is dispensed. Add a warm or cold flush before the hot or warm wash bath. Make sure the water level is high enough to touch whatever you are washing. It will help. Energy star is great but it wont matter how much water you save per load if you need to wash something 3 times.

Can I buy this washer and stack with lg stack kit a lg 403kwta9m785 gas dryer?  The lady at Home Depot says the above washer wasn’t made to stack... I don’t think she knows what she is talking about since your accessories lists a stacking kit as an option

Asked by: Robin47
The ENERGY STAR® Qualified LG 4.5 cu. ft. Ultra Large Capacity with Steam Technology, Model # WM3670HVA is a stackable washer and any Stackable LG Dryer that has a width of 27" can be stacked onto the washer using the 27" LG Stacking Kit, Model # KSTK1 manufactured 2009 or later. Regrettably, what we cannot confirm is the model number for the Gas Dryer (403kwta9m785) that you have provided. Most LG Gas Dryers will have a model number that begins with "DLG", "DLGY" or "DLGX". Please check the model number for your Gas Dryer again. The model number you have provided looks like a serial number. ^IFV
