Neptunes are crap. There was a class action lawsuit several years ago, because of so many people having terrible problems with mold growing in the machine. Of course I found out about it after the deadline and just had to junk our POS Neptune. That was alot of $$$ down the drain. I will never buy Maytag again...or whatever their new name is.
I've got a LG front loader now. It works great. You can get some decent deals at Home Depot for not only LGs but all the other brands...I think our's were 10% off, free delivery/haul away, and like a year or 2 of no interest.
Also WRT the sock issue...it's fairly common in alot of machines. Especially if they are little kid size socks. They are just small enough to get sucked up with the water going out. If you put them in one of those mesh washing bags, you'll be ok.
bingo!! the mesh bags will save you a $100 service call when your washer won't drain. just be sure to watch the repair person so you don't have to call them again.
