I purchased a Bosch dishwasher 7 to 8 years ago when I worked for Bosch power tools. I thought it was a good machine and we have used it a lot. However, last week the machine quit and will not turn on. I am waiting for the repairman now and shudder thinking of how much it might cost to repair.
Is there a brand, moderatly priced, that will work well, clean well and have some longevity? The last one we had, a cheaper Whirlpool, lasted over 15 years but I hesitate to buy another Whirlpool for a lot of reasons.
We put in a KitchenAid when we bought our current place about seven years ago and have been very happy with it. It cleans very well, has a built-in disposal so you don't need to rinse your plates, just scrape them, it does a good job on both heavy pots and delicate glassware, and it's quiet enough to run while you're having a conversation in the same room. Plus the stainless steel interior keeps it looking new.
As I recall they ranged from about $400 to $700 back then (probably a bit higher now), and most of the differences among models were cosmetic, not performance-related.
I live in the high plains of Texas where the only thing worse then the weather is our water. It routinely eats up dish washers in 5 years or less. If you want something that will last for ever and can wash dishes with no presoaking might i suggest getting a commercial auto chlor type unit. I put one in my home and wouldnt trade it for anything. You are going to pay at least $400 up to 800 depending on newness, however you can easily save this money by never having to buy another dishwasher, your commercial soap costs next to nothing, and it uses relatively little water. All this and it washes, sanatizes, and leaves your dishes spot free in 4 minutes.
Be careful about going this route however: since i first did this i have installed a 3 compartment sink, a hatco, a steam tray, and wanted to turn my pantry into a walk in, but the wife put her foot down. She told me that if i wanted to be in a restaurant so bad i should go to work.
