Well, I'll be...were I in the marketing department at Frigidaire, I'd roll out the "Our crappy low-end dishwashers clean just as well in cold water as in hot!" as quickly as possible.
To be fair, I had a 2002 TOL Frigidaire dishwasher for five years and it was a competent, reliable, quiet (by the standards of its day) machine. It didn't handle difficult pots/pans issues as well as the Maytag that followed it (which in turn didn't do as well as the LG which replaced it) but otherwise, I had no complaints. It was the first machine I had with alternating rack washing, and I loved the single rack option.
I'd never recommend one of Frigidaire's lower-end models, though. They have been poor performers consistently over the years.
