Hi all, Moved into a house for college with some of my friends, and so far the house is pretty awesome. However, our impressions with the dishwasher have been less-than-stellar, and I figured I'd query the wisdom of the members here. this is a very basic dishwasher, so I'm not expecting the greatest performance, but this thing is struggling to remove light soil from items on the top rack at times, and redeposits in glasses are the worst I have ever experienced. there is about a 1/4 inch of water left around the sump intake grate after every cycle. is there anything I can do to make this thing better short of convincing my landlord to let me replace it with a powerclean!?
