    Lots of features

    I've been interested in washing machines since I was bout 3 or 4. From my grandmothers old washer with a wringer attached to the new machines with sensors and electronic controls. I bought this as part of a set to replace our 20+ year old set which was still working well while the new ones were on sale. If anything broke on the old machines the parts were mostly "NLA" and the new ones probably would not be on sale at that time. We have had this washer about 3 months and this is our second front loader. The different cycles are handy. Originally, I thought that all those choices were silly. I had alway selected the basic wash cycle, adjusted the wash time, the spin speed and wash temperature. Now, one selection can do all of that. Depending on the load, I sometimes need to select"Cold Wash". I like the one-button selection for "Cold Wash" and the button for extra rinse(s). I didn't pay attention at first, but I recently realized up to 3 extra rinses can be selected, not just 1. I have used the Prewash cycle a few times on especially dirty items, along with an extra rinse to be sure they were rinsed thoroughly. The clothes came out bright and clean, even using the cold water wash. I have used the steam function a few times and it seems to help clean. We have a couple old, white bed pads that we lay on the floor near the back door or outside for the dog. They had developed stains in the center. When I first washed them in the new washer, the stains were gone, but I thought that it looked like the white bed pads had a slightly yellow hue to them. I washed them a couple more times when they had become dirty and hoped to see an improvement. I tried warm water and hot water and finally used steam. The steam brightened them up. In my opinion, that was a pretty tough test. Old dirty, white bed pads can be hard to get totally clean looking. I like the WiFi feature that, in conjunction with the LG app, sends an alert to the cell phone and even the LG television when the load is done! I also like that LG installed a drain hose for the pump filter. Our previous front loader did not have that. The washer nad dryer are in a small utility room with no floor drain. I would have to drag the washer to face out the door to the back porch, then open the pump filter and let it drain onto the porch. After checking and cleaning, I had to put the cap back in, put the front panel back on and drag the washer back into place. I say all of that so those who have never had a front load washer before can appreciate what LG has done with the flip up access door and drain hose. The LG washer is much, much quieter than our previous washer, which was quieter than the top loader that it replaced. It sits on a wood floor, above the ground and I often don't know if it is running unless I look at it (from about 25 ft. away) or I am close to it. No more rumbling and shaking of the house on spin cycles. We have a queen size bed and as large as our previous washer was, we could only 1 bed pad with maybe 1 sheet or 1 comforter at a time. This washer will handle 3 bed pads or a comforter and a bed pad with ease. According to LG, it can handle a King size comforter. Ok, if you have made it this far ... it does a good job cleaning clothes, has lots of cycles to help determine what is best for the load that is being washed, it is quiet and the WiFi feature with the app. is cool. It will even notify you if you are away from home if your phone has access to the Internet. And there is the way that it holds the door open slightly to allow air in to dry the interior. Following the suggestion in another review, I wipe down the gasket, glass and inside of the door when I am through washing for the day. I forgot to mention the size. Our house was built in the late 50's. The utility room was designed for a top loading washer. The front loaders can be a little bit larger.The space is limited by a door that swings across in front of the washer. at the left corner where the dispenser door is located` I had to be careful of the dimensions of the washer. This washer fits the space with enough clearance that I can pull the dispenser door out a little bit to allow it to air dry without the door hitting it. Based on my many years of experience with washers (and dryers), the design of this washer was well thought out. I will give it 5 stars for now. I can't speak to reliability yet. Because of all of the electronics, I purchased an extended warranty. I had a circuit board go out on the previous washer and that was covered by an extended warranty. The replacement would have cost more than the extended warranty did. That was the only service call for that washer and drier for over 20 years. LG is supposed to be very reliable, but even their equipment breaks done. Just something to consider.

    Best washer I’ve owned so far!

    This is my first front load washer and like the performance so far. My family is a family of 8 and we don’t have to wash every day with this washer. I had a small problem with the sound of the washer, it had stopped sounding when it was finished and no sound when turned on or off. I have a one year old son who follows me everywhere and kept pressing buttons so I thought maybe he broke it. I called the customer service number by the door on the inside and the problem was fixed in less then 5 min all together. (My son had pressed the on/off button for signal) so if you don’t like the music it CAN be turned off. I haven’t had any problems with the washer and the noise is minimal comparing to my top loader that I use to own which it would always go off balance and make very loud noises. This is very minimal but like everything that is electronic has to have some noise to it. I can hear my television and phone fine while it’s washing. I can hear my one year old on my second floor fine as well. Turbowash is a must. It rinses your clothes and saturates it while spinning. I do notice it has no water when on regular wash, but turbowash is on and off throughout the washing time. I did notice that on the “towels” selection it does keep some water in the drum while it washes along with turbowash if selected. The longest time that I’ve seen so far is 1 hour 20 minutes. The shortest time is 30 minutes. It does weigh your clothes, but I found out that if I select a different soil level it does change the minutes, if I feel it’s too long of a wash before it starts running I press pause and select a low soil level and the minutes lower. Also the spinning is quiet enough and not loud at all, the dryer is louder. I have washed comforters and pillows and it does wash and dry good. It spin drys very well to where thin material can be hung dry. Over all I have little ones and they get very dirty and the clothes come out clean I use “Shout” for very stubborn stains. My little ones like helping and they can reach perfectly and it doesn’t the height with out the stand does not bother me since I’m short in height.

    Love my LG!

    This washer is so easy to use. I love how I can now wash twice as much in a load as my previous 14 year old LG washer. It has a lot of options for how you want each load done, and it is quiet. I even feel like my clothes are cleaner than they used to be. I got a great price by getting the LG electric dryer too. This is a purchase that will save me money and time too.

    Smart, Sleek, and Worth It

    The washer works great and looks really sleek in black steel. It runs super quiet, cleans clothes really well, and the smart features make it easy to keep track of loads. Definitely worth the price for the quality.

    Powerful, Quiet, and Smart

    This LG washer is easily one of the best upgrades I’ve made to my home. It’s quiet, fast, and surprisingly efficient. The built-in intelligence is not just a gimmick—it actually chooses the right cycle based on the load. No more guesswork. The 4.5 cu. ft. capacity is more than enough for large loads, and the steam feature helps eliminate odors and deep-clean heavy fabrics. Clothes come out clean and fresh every time. It connects to Wi-Fi and sends notifications when the cycle is done, which is a nice touch. I’ve stacked it with the matching dryer and the setup looks clean and minimal. Only small downside: you need to keep the door open after use to avoid moisture buildup (common with all front-load washers). Not a dealbreaker. If you want a washer that does the job right the first time and adds smart convenience, this is it.
