Product review (2 stars): Worst purchase of '15-'16
You basically have to wash the dishes before you was the dishes. A few times the water wouldn't drain from the bottom. Of course I checked the filter.  Nothing in the filter.  At this point the dishwasher is approximately five months old. So I have no idea why it wouldn't drain.  In addition for a while after I had used the dishwasher I found black specs visible on the white surfaces of my dishes. I have no idea where these came from.  I tried running the dishwasher without the filter and the black specs went away. Again no idea why. So this was the worst purchase of 2015 and 2016. I can say that the dishwasher gets very hot. So at least I know it's sterilizing my dishes.
