What people are saying

Rated 4 out of 5 by from Short Drain Hose and WiFi Incompatability So far so good, as far as washing is concerned. Clothes are cleaned thoroughly and there have been no problems in the first two months. Here are two features that might affect your decision, however. 1) the drainage hose is less than five feet long. You'll need to purchase an extension hose if your drain is not directly behind the washer. 2) The WiFi feature doesn't work at all with a dual band router (2.4 and 5 GHz). You need to make sure you have a single band 2.4 GHz router if you want to enable the WiFi.

My clothes are always warm when I remove them from the washer.  I prefer a cold water wash and rinse.  I know how to change the wash to tap cold but they always seem to be rinsed with either warm or hot.  I am ruining my closed clothes.  Please help.

All rinses for the ENERGY STAR® Qualified LG 4.5 cu.ft. Smart Wi-Fi Enabled Front Load Washer with TurboWash™ 360 Technology, Model # WM3900HBA use tap cold water. If your rinses are using warm or hot water, check to make sure that you do not have the hot and cold water hoses connected in reverse to your hot and cold water taps...^IFV

What is True Balance and how do I know if its working? I had a 15 year old LG front loader prior to this model. When the spin cycle starts the machine seems to be out of balance way more than my old one. I do have it on a sidekick. but shakes too much.

Asked by: Jim FL
The TrueBalance™ Anti-Vibration System for the ENERGY STAR® Qualified LG 4.5 cu.ft. Smart Wi-Fi Enabled Front Load Washer with TurboWash™ 360 Technology, Model # WM3900HBA balances uneven loads and reduces noise to a minimum so you can run it anytime, anywhere. IT is enabled by LG's Direct Drive Motor technology. With Direct Drive motor technology, power is transferred from the motor to the drum rather than through belts and pulleys which significantly reduces any noise and vibration. Additionally, TrueBalance™ technology automatically counterbalances uneven loads and adjusts spin speeds to further reduce vibrations. However, you still need to ensure that the washer is installed on a solid floor that is strong and rigid enough to support the weight of the washer, even when fully loaded, without flexing or bouncing. If the floor has too much flex, you may need to reinforce it to make it more rigid. If the floor is not solid, it may cause severe vibration and noise. Before installing the washer, make sure the floor is clean, dry and free of dust, dirt, water and oil so the washer feet cannot slide easily. Leveling feet that can move or slide on the floor can contribute to excess vibration and noise due to poor contact with the floor. The washer must be installed on firm flooring to minimize vibration during the spin cycle. Concrete flooring is best, but a wood floor is sufficient, provided it is built to FHA standards. The allowable slope under the entire washer is a maximum 1 inch (2.5 cm) difference from side to side or from front to back...^IFV

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
