Product review (1 stars): Do not purchase this HE washer
I tried to post review on Whirlpool site but it never was approved. That would explain majority of the positive reviews on their site. We purchased our washer/dryer set at Costco since they have a wonderful return policy. This set is going back because of the washer. The actual washer model is 5810BW which is made specifically for Costco. It is the same as 5800 BW sold here. This washer does not rinse the detergent out of our laundry. After the first use whole family was itching because of the detergent left in the laundry. We have been using the same detergent for many years and in fact we used up most of this bottle with our old washer. I also am aware of differences between HE and regular machines and specifically checked instructions on the amount of detergent to use. It is Kirkland Signature HE detergent so it is designed for this washer. After the first fiasco I started using less detergent - 1/2 to 1/8 of recommended amount. The itching stopped but if our laundry had any stains they would not come out.  With our old washer (also Whirlpool and also from Costco) I just had to pre-treat with a Shout spray and toss it in the washer. All stains would usually come out. With this washer I had to wash one t-shirt 3 times to get a stain out. How is this saving water? I also use additional rinse cycle for all of the loads because I have no desire to itch again. How is this helping with the water use?
I took a video of the washing cycle since the washer has a glass lid. You can clearly see the white item sitting on top of the load throughout the whole washing cycle. Small items do circulate through detergent but larger items stay in one position and do not move. When I hand wash items I also do not submerge them in to the water and rub. I use a little detergent and rub the item against itself, but this is not what this washer does. The washer just moves its "washplate" back and forth and wet items just vibrate on it.
I use dress shirts from Costco which are treated with water repellent. This washer cannot get this shirt wet on normal cycle. I have to use deep water cycle to even get the shirt wet. First time I did not believe my eyes - had to open the lid and make sure that part of the shirt was dry at the end of the wash cycle! The heavier items like bath towels do not get clean and stink after the first use. This rarely happened with our old washer. And don't get me started on the "spray rinse". I am not sure who came up with this concept and what it actually rinses. If you watch videos of Samsung or LG HE top loaders, these washers have a nozzle which sprays water ON your laundry that is stuck to the sides of the drum after a spin cycle. I can see how this can do something like rinse. This washer just pours water at the center of the drum from where it happily drains in to the holes in the bottom. How this can possibly rinse anything is way past my understanding. There is no way to overwrite any of the settings or add a little water.
The sensing process is unreliable. If I put few small items, the washer will add a lot of water, 5 inches or more, and the items would be swimming. It I put larger item, like a towel, it will absorb all the water and there would be almost no water in the tub. Ether this technology is bad or Whirlpool's implementation is bad.
The only good thing I can say about this washer is that it spins laundry very well. The laundry comes out much drier and therefore dryer does finishes much faster. This is well compensated by washer taking more that twice as long as our old "inefficient" washer did. I should have fixed our old washer instead of buying this new one, more so since I already diagnosed what the problem was. We thought to update our 14 year old set with the new one - what a mistake.

As I understand it is the government that is mandating these water and energy savings. How about starting from the government itself? On my way to work I see on-ramps being watered every morning, being that it is drought in California and all. How about saving water there? Also mandate more water efficient landscapes instead of planting grass everywhere. I wish the government would stay the heck out of my laundry room.
