Product review (5 stars): SHE55M15UC Dishwasher
This is an exceptional unit.  I have had KitchenAid, Bosch and Maytag dishwashers previously, and each successive unit seemed more quiet than the one before.  This unit replaced a Maytag that just didn't clean well anymore after about 8 years of operation.

I was a little concerned about this unit not being a self cleaner as I didn't want food recycling back onto the dishes -- a problem I have had in the past.

So here is the scoop.

1. The unit installs easily.  Be careful with the door top though on installation as that can get scratched if you need to "jimmy" the unit in (sometimes if you have hardwood floors that don't go all the way into the dishwasher bay this can be tricky).
2. This dishwasher cleans as advertised.  It washes dishes without pre-rinsing, and ones that have one day dried food also.  It is a superior washer.
3. This dishwasher is quiet.  Wow, is it quiet.  Of all the units I have had it is probably half as loud.  I have always aimed for good quality units, so the others were not bad.  This unit makes less noise than the 2 fish tanks I have in my kitchen dining area.  It is that quiet.  Great job Bosch.
4. OTHER: The unit has LESS water wands than previous generations of dishwashers.  My Maytag had 4 wands. This unit has 3 (well 2 wands, and a sprayer assembly on the very top).  I suspect they use less for higher pressure.  Whatever it is, this dishwasher cleans. It works!  Great job Bosch.
5. OTHER: The food waste filter has not been an issue.  Most little food scraps are getting cleared from the washer. Also, the filter is not getting grimed with grease as I had experienced with a previous unit.
5. Negative: not a biggie, but the wine glass holding facility is a bit weak -- you need to be careful opening the upper tray if you have wine glasses, or they will move and potentially break (yeah, I broke one).
6. Negative: you do have some flexibility in installing the unit on how far "out" the door protrudes.  If you install it protruding too much, then watch out if you use the counter top above the dishwasher as you may rub up against the on button. If this happens, you will need to adjust the unit farther in.

Overall, I highly recommend this dishwasher.  It cleans and it is quiet. It looks very sharp in stainless steel.  And you don't need to wash your dishes beforehand in order for it to work!
