It's a KA KDTE254ESS1. Over the years I've had 5 dishwashers and this is by far the best, even beating out my GE 2400 from the '80s. Love that both the racks are on ball bearing glides and find the 3rd rack pretty useful too. I clean the filter monthly roughly, never too much stuff there. I do find performance suffers a bit if I run out of rinse aid. I do keep my water HOT, set as high as the heater will allow, but the DW uses such a small amount of water that after the first rinse the water has cooled down, I have a long run to the kitchen about 30'+ so if I think of it while it's running I will turn on the faucet and run some hot water. I do use the Sani rinse option but never use heated drying, if I open it right after the cycle ends the dishes flash dry, but mostly I just unload in the AM when I get up, often the interior is still a little warm.
