Frigidaire Professional Series —
I thought it was the age of my other dishwasher that made it necessary to rinse every bit of food off of my dishes before running the dishwasher. Turns out my brand new dishwasher has the same requirement. I find that it works best to was every load on the pots and pans cycle, too. I often find residue in the bottom of my drinking glasses...I'm starting to wonder if I have a defective machine.
