What people are saying

Rated 5 out of 5 by from LG washer/dryer Basic review submitted for chance at $500. Lots of laundry to do in my house. I bought the extended warranty this time around. I’ve had good luck with this brand. Only time will tell how this combo holds up.

Rated 5 out of 5 by from EXCELLENT MACHINE Have had washer and dryer for several weeks. They are excellent. Great replacement for 20 year old Sears machines.

Rated 4 out of 5 by from We love our messages! We are enjoying that the washer lets us know when the cycle is finished. We often text each other at work to say hey go empty out the washer. The only issue we are having is that after every cycle even when we choose "cold wash" the clothes feel warm or hot. The washer says all rinses are in cold water but not sure mine is doing this.

Is this model WM3900HWA (and DLEX3900W) NSF listed/approved? 

Asked by: Lori19
The Allergiene™ Cycle in the ENERGY STAR® Qualified LG 4.5 cu.ft. Smart wi-fi Enabled Front Load Washer with TurboWash™ 360 Technology, Model # WM3900HWA is officially certified by the Asthma and Allergy Foundation of America (AAFA). The Sanitary cycle reduces 99% of bacteria on laundry through high temperature. To earn NSF Protocol P172 certification, a clothes washer tested under this protocol must be able to reduce 99.9 % of microorganisms when clothing is washed on the unit’s sanitization cycle. The specifications for the washer do not list NSF Certification for this washer. The Anti Bacterial cycle on the ENERGY STAR® Qualified LG 7.4 cu.ft. Smart wi-fi Enabled Electric Dryer with TurboSteam™, Model # DLEX3900W, on the other hand, is certified to reduce 99.9% of bacteria on laundry, and that none of the bacteria will carry over onto the next laundry load by NSF International (Protocol P154 Sanitization Performance of Residential Clothes dryer)...^IFV

The specs indicate that the Door is glass/chrome. However the rim in all product photos looks black. Photos for some previous models such as the WM3700H*A washer show bright chrome rims around the windows. Are the *3900 series trim rings black or chrome?

Asked by: Daniel Jay
They have changed the ring now, it’s not the polished chrome anymore. It matches the washer color more closely now.

Can you confirm that the matching heat pump dryer has been canceled? The LG rep was at my local appliance store while I was visiting and he mentioned that the DLHC3900 was discontinued.

Asked by: olesamo
If the LG Rep mentioned that the Heat Pump Dryer Model # DLHC3900B has been canceled then that would be confirmation in and of itself since he would be the one to notify the stores that he supervises...^IFV

So Facing Appliances =- My washer needs to be on the right side of my dryer. So my question is can the door be switched to open left to right -- rather than right to left?

Asked by: DDTT
No, the door on this washing machine is not able to be reversed.

What is the maximum wash load by weight?

Asked by: sstreky
Unfortunately, there is no way to convert the cubic feet capacity for the ENERGY STAR® Qualified LG 4.5 cu.ft. Smart wi-fi Enabled Front Load Washer with TurboWash™ 360 Technology, Model # WM3900HWA into pounds since one measurement is a volume measurement and the other is a weight measurement. A cubic feet capacity of 4.5 cu.ft. will hold about 18-20 lbs of laundry. However, keep in mind that clothes weigh a lot more when wet than they do when dry. The recommendation is to load the tub about 3/4 full and not to stuff the clothes in the machine or pack them in. You may want to weigh your laundry basket on a scale to see how much weight that would be to get an idea...^IFV
