I have a GE gtwn2800 that I bought in July 2012. According to the questions and answers that I have read about this machine is is not a hydrowave model. It is the closest washer to a traditional toploader, next to a Speed Queen or a vintage toploader that can be bought. It has a very large capacity, there is no ATC, hot water is tap hot. If i use the power rinse setting, which I always do, it spins and rinses just like a traditional washer. I have had no problems what so ever during the 2 1/2 years I've used it. I have washed king size down comforters, king size bedspreads and king size pillows, 2 at a time with no problem. I has never gone out of balance, spins every time ii is supposed to and cleans excellently. I have found that the dry times are really no longer than they were when I've had machines that spun at 1000 rpm. I believe that this model compensates for the slower 640 rpm spin with a longer spin time. Even so, using the longest wash time setting, highest water level and hot water, which fills slower, the cycle completes in 50 minutes. For the price it can't be beat, and I would buy another. I do however feel guilty that it uses so much water. And it may not have the longevity of a Speed Queen, but that is yet to be determined.
