The only comment I'll add here is to look at cycle length times. When researching a new dishwasher purchase, everything that I read said how the cycle times had been so extended. Because the DW's (and guessing clothes washers as well) are so low water consumption that the wash and rinse cycle times have been extended unbelieveably. My DW takes over 2 hours to run a cycle and that's without drying time! So, while we're saving water with our appliances, we're using considerably more electricity to run them!
