whirlpool washing machine problem

My crappy hotpoint dishwasher is making my dishes dirtier than when i put them in. It's small crappy low end, so i just want to replace it. I need a 24" built-in. Typically when shopping for something, i check reviews on Amazon. Unfortunately Amazon has very little reviews on dishwashers. The big retail stores have fake reviews, so I'm kind of at a loss as to how to find a good dishwasher. I don't want to waste money on something that doesn't clean any better than my current one. So can anyone recommend a good 24" in the $400-1000 range? That's pretty much my only criteria for purchase, price and quality. Obviously the more room the better, but bells and whistles and washer noise volume aren't too important to me.

I have a Samsung electric range with convection oven, and last night the circulating fan for the oven remained on. Typically, the fan comes on only when either convection mode is selected or when the oven is warming up in conventional mode. In normal use, when the fan is on, it shuts off automatically whenever the door is opened. But starting last night, the fan started running continuously even when the oven was turned off and completely cool, and opening the door had no effect. Any thoughts on the problem and possible solutions would be greatly appreciated. Thanks
