Hmmm.
I have a Frigidaire model that is between 5 and 10 years old that replaced an old Maytag from the 90s with the mechanical dial—I wished I know then what I know now.
For the longest time, I couldn’t figure out why this appliance was not working well. My mother has an older Frigidaire that works well, and she never “washed” the dishes before they went in. Something called energy guidelines happened in that span of years.
Part of the reason seems to be that phosphates were removed from dishwashing detergent as Cascade Boil Out definitely has made a difference! I still use a lot of water rinsing the dishes to get all the residue off before putting in the machine. I then choose the hottest water temp and drying cycles available. It does a respectable job now with this method.
These energy regulations have caused many of us to use more chemicals, more loads, more time, and more energy to do the same thing in less time with less resources. The landfills are filling up at alarming rates when you consider this new thinking that also involves a less expensive up front and buy more often affects printers, tires, car batteries, sealed electronics, appliances, and lots more.
