Thanks for all the good responses. Enjoyed reading through those. Dan, it sounds like something might be wrong with your machine. Surely what you describe can't be normal operation, can it?!
If the model with the Clean Water Wash system in my first photo (KDTM354DSS4) is still for sale when I get back to the US, I'll pick that one up for a start, as it's by far the closest to where I live. It'll be interesting to try the ProScrub jets. The reviews of this model seem to say that performance is excellent and it's extremely quiet and dries great. CR rated it very highly. Unfortunately a lot of reviews complain that it doesn't last long -- the wheels fall off the lower rack, the upper rack sometimes suddenly comes crashing down if the support rails break. And the filter can tear itself apart, which can lead to two problems: either the machine keeps working (just about) but the spray arm holes get blocked up and the wash performance is poor. Or the torn filter will jam the pump completely, which causes the motor to overheat and stop working. The other problem is that the control board sometimes dies completely. But I'm happy to take a chance on a used machine. I'd like to try other models too, including the ones mentioned in this thread. Thanks so much for sharing your experiences and knowledge.
