Yes, Frigidaire dishwashers are pretty crummy. When my Mom moved about a decade back, there was a new BOL Frigidaire tall tub. Ugh! Miserable performance. Didn't clean well, and if you didn't pre-rinse dishes it left all kinds of crap in the tub. We replaced it with a Kenmore sensing short-tub which is much better. I tell my Mom to always use the hi-temp option to assure two full rinses.
(Funny, story on the Kenmore. When it was installed the detergent dispenser wouldn't open. Two repair guys came out, replaced the motor/solenoid that releases the detergent door twice and were ready to replace the who machine until I went over one night and realize that the lower rack was in backwards!)
My Whirlpool is a short tub, (cannot recall the model), with silverware in the door (anywhere basket), and I usually use the Normal wash with hi-temp to get a full pre-rinse and two full final rinses. I still feel compelled to rinse again afterward which I used to do with my old dial machine. On the dial machine, when it would fill for the final rinse, I could turn it back to the "rinse and hold" spot which would effectively give me three rinses, with only the final getting the rinse aid. On the new machine, I can't really do that. I can do a rinse-only afterward, but I know I don't get the hi-temp or the rinse aid.
