What people are saying

Rated 5 out of 5 by from This washer truly is a champ! Pros: - Washer is ABSOLUTELY SUPERB at washing and rinsing clothes! - Uses VERY little water and still manages to get clothes sparkling! - HUGE capacity! - Sanitary and Bedding cycles are great! - I find this washer to be SUPER quiet...even on the highest spin speed setting! Not Game Changers for us but things to consider: - I found there was a learning curve when using this washer. Not a “set it and forget it” type of washer. But only took me about three days to figure out and I feel it’s really worth it! (Seriously....VERY trivial) Cons: - Brightest Whites cycle is a disappointment....can’t select Extra Hot water. Better off using Sanitary or Allergiene cycles for whites. - Cold Wash option is useless....as I can simply select Cold as my wash temp...would MUCH rather this had been a soak option instead. - No light in washer - Cannot stand the tinted windows Verdict: Aside from very minor caveats, this washer is truly excellent for the purpose it serves!! You should seriously consider giving this washer a look when shopping for one! We really love this LG unit and it truly fits our needs quite well!

Rated 1 out of 5 by from Not enough water I bought the LG steam inverter direct drive washer and dryer. The washer is HORRIBLE!!! How can the clothes wash if there is not enough water in it. The clothes still smell dirty and has a strong detergent smell like it was just thrown onto dirty clothes. All of the clothes don’t even get wet. I cut the amount of clothes I put in the washer in half and they still smell.. I hope LG fixes this problem. I understand the point is to conserve water, but if I spend this much on a washer and dryer I don’t mind having a little bit more water in the washer. I had such high expectations and was severely let down. If this is the type of products LG puts out, I will not be buying another. Now I’m contemplating buying another washer to replace the one I bought just 2 months ago

Rated 5 out of 5 by from Great washer! Really happy with purchase I have had the washer a couple of months now. Mostly good things to say about it! - The cycles are pretty fast. The fact that the cycle duration is based on sensing the load is huge plus. - Cleans well - Fairly quiet. Certainly a lot quieter than the machine I replaced. - Lots of pre-programmed cycles -- more than I can use. Haven't felt the need to download additional cycles. - People have complained about the display. I personally find it easy to read and it provides me a lot of information. - The ability to leave the door open a bit after a wash is a huge plus. Hopefully the air circulation will help prevent mildew. - The cell phone integration is actually useful. I often forget that there was something in the laundry, and I have left wet clothes in there for long period in the past. The phone alert of a cycle completion seems to reduce the chances of that happening significantly. What I didn't like: - The app is clunky to setup. I think it could be significantly better. The real question of course is the reliability, and I wouldn't know that for a while to come. Additional point: I bought it from Costco, which uses an independent firm for the delivery and installation. I have nothing but high praise for the installation process. They kept me informed about the time windows on a frequent basis, the truck arrived here on time, and the installers were extremely courteous, careful, and efficient with the installation process.

If I ordered the LG 3900HWA washing machine in black and the sidekick pedastal, what is the total width, height and depth? Also, what is the cost of both? Are there any current rebates? Where’s the best place to buy it in 32169 zip code?

The washer has a depth of 30 1/4" and the LG Sidekick™ Pedestal Washer has a depth of 30 3/4". The washer has a height of 39" and the pedestal washer has a height of 14 1/8" so the total height will be their combined heights which will be 53 1/8".

does this model have an internal heat sensor

Asked by: sizzle2009
Hi sizzle2009. We would need some clarification about what heat sensor you are inquiring about. Like all other washing machines, the ENERGY STAR® Qualified LG 4.5 cu.ft. Smart wi-fi Enabled Front Load Washer with TurboWash™ 360 Technology, Model # WM3900HBA has a thermistor which is essentially a resistor that changes its electrical resistance at varying temperatures. Thermistors are used in washing machines because their electrical resistance at various temperatures is known, it's easy for the washing machine to monitor a thermistor and detect when certain temperatures are reached. Thermistors are sometimes called NTC sensors or NTC Thermostats. Hopefully, that is the sensor that you are inquiring about? ^IV
