Congrats on the 3033... tis basically the American version of the UK model W2652 I own. 70*C is still a very reasonable temp, I wouldn't worry too much about it as you will very rarely need above 60 degrees/140*F anyway.
nclh77... in terms of water soaking through the clothes, that is actually why the drum tumbles in such a way. It will start off slowly to allow water to be plunged and squeezed through the load, speeds up to the distribution tumble to agitate and force water and detergent through the fibres, slows down again to squeeze and plunge the load, and then reverses. Although this action only takes place for the first part of the wash cycle - the last portion of the cycle, at least on the EU machines, is standard 55rpm tumbling backwards and forwards, with a couple seconds pause in between. You are right though in that this action is what causes a lot more sudsing; in fact I've found you don't need that much detergent compared to other frontloaders thanks to the distributing portion of the tumbles.
