Product review (4 stars): Highly recommended
We actually intended to purchase the KUDE50FXSS because it is cheaper but our 9.5 yr old Fisher Paykel died at Thanksgiving and, by Monday, I was anxious to get a replacement installed. The appliance store was out of the KUDE50FXSS because it is such a popular model, but they had a floor model of the KUDE70FXSS on sale for less than the one we wanted, so I took it. I didn't really want the very top (third) rack that one reviewer raved about and after about three uses, we removed it. The top (second rack) has two positions. In the 'down' position, it interferred with some of our dishes in the bottom rack, and in the 'up' position it interferred with the very top rack. Fortunately the very top rack is very easy to remove.

This DW has more features than we need and I don't like heated dry because it is so hot. Frankly, the final rinse water is hot enough that dishes dry on their own in the dishwasher. I have tried washing glassware along with a couple of greasy microwave bacon cookers and have tried washing some really dirty pots (in pot scrubber mode) along with glassware, and everything came out very clean both times. The filter needs to be rinsed infrequently and all the rack adjustment options make it really easy to load. Some customers may like all of the wash options and those who don't can just ignore them. For the majority of people, I suspect that the KUDE50FXSS would be just fine.

There are some plastic parts that are too delicate. We had to order replacements for several of them because numbskulls had broken them while playing with the unit at the appliance store. Also, the utensil rack has several plastic inserts with slots designed to keep your flatware separated so it won't "spoon". Our flatware doesn't fit in the slots so we removed them also. We have washed with cascade powder and Finish Powerballs. Both seem to work well and we mostly use the powerballs now. We also use JetDry in the dispenser.

This unit is so quiet, you actually have to listen very carefully to detect that it is on. The loudest sound is heard through the disposal when it empties. We highly recommend this unit, or the next one or two down, which most customers will likely find just as acceptable at a lower price.
