Admittedly, I've had this washer (and the matching dryer) for only a couple of weeks, so everything I'm saying is based upon my first impressions. This was a replacement for an out-of-warranty, 9-year-old Kenmore Elite front loader that had begun to experience electronic issues and failed washes. After evaluating the cost (and time) to have it repaired, I decided that a new washer (with a new warranty and service plan) would be my best choice. I chose the LG WM5000 and matching dryer.
One of the selling points for me on this washer was its size. For my needs, the 4.5 cu. ft. capacity is more than adequate. (I've already washed a king-size comforter.) Yet, the machine itself is small enough to fit within my laundry closet (which has a 37" depth.) Note that you can't stack this particular set because the detergent and bleach dispensers are under a sliding door on the top of the unit. However, that isn't a concern for me as my closet is designed for side-by-side installation of the washer and dryer. I also chose not to purchase the optional add-on 'Sidekick' (pedestal) washer since I really don't need the extra capacity, but it's nice to know that I can always add it later if I need to.
Best Buy's installation was excellent. They arrived on time and quickly had the new washer/dryer set installed, balanced and tested. Of course I couldn't wait to try my first wash. The first thing I noticed is how quiet it is. My Kenmore front-loader had something called "Quiet-Pak", and I thought that was really quiet. This LG is even quieter, so much so that at one point I walked back into my laundry area just to make sure it was running. This washer also seems to balance the loads really well, and has a much better anti-vibration system than on my previous washer. (My laundry closet is on the second level of my house, so vibration is a concern of mine.) No problems whatsoever though.
As for the wash itself, my clothes came out very clean and smelling fresh. So far, I've only used the Normal and "Speed Wash" cycles but haven't yet tried the steam. Just as with my previous washer, there are likely to be cycles and settings that I'll never need to use. Still, the normal cycle completes in about 40 minutes, and the speed cycle completed in less than 30 minutes. Obviously, adding options (such as extra rinses and steam) will add to that time. (It's also nice to be able to turn on the drum light mid-wash to see how things are going.)
Regarding the WIFI, as some have noted the phone app wasn't the most straightforward to set up. In my case, I have two different wireless routers in my house, both of which are supposedly compatible with this washer. Yet, for some reason the washer refused to connect to the router I wanted it to, and would only connect to the other one (with the weaker signal.) After figuring out what was going on though, I was able to get the WIFI feature up and running. I'm not really sure how useful it will be in the long run. For now, it's a bit of a novelty to have my cell phone alert me when the wash is done. I can also start the washer remotely and monitor its progress. (Will I ever really need to use that feature ... who knows?) Unfortunately, the one WIFI related feature than might have been the most practical and useful, 'Smart Grid', is one that I can't use. That's because 'Smart Grid' requires support from your utility company, and mine does not support it.
The only other thing I'll note about the WIFI is that it seems that iPhone support is either limited or non-existent. (Supposedly iPhone support will eventually be available.) I'm an Android user so it doesn't affect me. However, I've noticed that some reviewers have lowered the rating of the washer, simply because of the (current) lack of iPhone support. I fully agree that if you're an iPhone user and the WIFI feature is really important to you, knowing this information and to sharing it with others is worthwhile. So in that respect, those ratings are fair and reasonable. However, although it works well for me as an Android user, the WIFI feature seems to be more of a novelty than a necessity. When researching the various brands and models, my focus was on whether the machine would adequately meet my needs in terms of washing my clothes. So based on that, and my limited experience with this washer, I give it 5 stars.
